We’re hiring our third team member, a full-stack engineer, to work directly with the founders across the Pinetree codebase. If you were here today, you’d be shipping notifications, building out the creator studio with analytics and video management tooling, and improving our Farcaster mini app experience and onchain features like direct payments to creators.
Pinetree is building the best onchain platform for video creators: a crypto-native alternative to ad-driven video platforms that gives creators real ownership over distribution, monetization, and their content. We’re looking for someone highly autonomous who brings solutions to complex problems and wants meaningful product and company ownership.
You should have experience writing and deploying production software in TypeScript, ideally on a small (<50 person) team or other startup environment, and be comfortable working across the stack (React / React Native / Next.js, Node, Postgres). Crypto or social product experience is a plus.
Stack: TypeScript, React, React Native, Next.js, Node, Postgres
Comp: $120–200k base, 1–4% equity, health/dental/vision, unlimited PTO, remote-first, $2,500 home office budget.
Reach out to giu@pinetree.so with a resume or links to work you’re proud of.
FUTO is an organization dedicated to developing, both through in-house engineering and investment, technologies that frustrate centralization and industry consolidation.

Machine Learning Engineer - FUTO Keyboard
FUTO Keyboard is a privacy-first software keyboard for Android. Every prediction inference routine runs entirely on-device; no user data can ever leave the device. We support over 150 keyboard layouts and languages, and over 700 layout + language combinations (not all of them include dictionary or predictions)
Swipe typing is an important part of the mobile typing experience for many. Applying machine learning here poses a unique challenge due to the requirement of needing to support so many layouts and languages, as well as user-added personal dictionary words (or even layout customizations!), with limited data. We have previously collected and publicly released a US English QWERTY dataset: https://huggingface.co/datasets/futo-org/swipe.futo.org/
We are looking for a machine-learning researcher or engineer to work through these challenges and help us improve the swipe typing experience in FUTO Keyboard.

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!
Our products:
* Merge Queue: Ensure your PRs keep the builds you care about green at any scale.
*Flaky Tests: Detect and eliminate Flaky Tests.
Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub Actions

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

At Profitmind, we're building massive-scale ecommerce datasets to use in AI training/inference, and we need a junior engineer to help develop the scraping infrastructure for product data. You'll be reverse-engineering undocumented APIs, handling anti-bot systems, and dealing with edge cases like pagination limits, rate limiting, and sites that change their protection schemes without warning. It's fun work! The technical side involves analyzing a site's network requests, deobfuscating and reading obfuscated javascript, and implementing simple HTTP request scraping to full browser automation. You'll also work on the infrastructure layer: state management for resumable scrapes, deduplicating products, data integrity, and monitoring systems to detect when sites change.
The work you'll be doing is in the hot path of our company, so the systems you will build need to be performant and maintainable. You should have solid Python skills and experience scraping ecommerce websites and APIs. You should also like the slightly-obsessive investigative nature of the work.
If you worked in scraping or botting in the past, please hit me up!

What sucked the last time you rented a house or flat? Come and fix it.
OpenRent is a force for good in an industry tarnished by rip-off agencies. Enabled by an unrelenting focus on technology, we now let more properties than any agency in the UK. In the last 12m we let over £50 billion worth of property, to over 8 million registered users, without ever charging any admin fees.
You'll be working on solving every aspect of the rental journey, from models to predict the right price of a property, to building the future of property management, all to help tenants find their dream home, and landlords their ideal tenant.
We're VC backed, profitable, and have plenty of ambition to maintain our fast growth in this absolutely massive market.
Roles currently available:
- Senior UX/UI Developer | Equity | 100k+ (based on experience) + quarterly bonus

BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, Posthog, and Brex automate the operations work that lets them provide their customers with world-class product experiences.
We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.
Joining us will mean solving hard problems at the frontier of AI adoption, including:
- maintaining performance at scale
- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.
- building agent and workflow systems that automate real work for customers
- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly
- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems
Stack: Postgres / TS (Nest + React) / Hasura / EKS / S3 / LLM APIs / Python
Benefits:
- unlimited PTO
- $100/mo education stipend
- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work
- health insurance

Hiring 4 full-time Software Engineers for low-level C++ systems work (HFT skillset), reporting to the CTO, team ex-Citadel, ex-Aquatic, ex-Bain
We're a cloud provider using GPU virtualization software to arbitrage GPU prices.
To our customers, we are a direct substitute for Runpod, Lambda, Coreweave, etc. with a simple UX and low prices.
Our advantage is we have spent 3 years bringing research technology to market which lets us use each GPU more efficiently than competitors. We can buy GPU compute, make it more efficient, and resell it at 60%+ profit margins.
We recently closed ~$4.5M of funding to triple our team size with a focus on recruiting the world's best low-level talent.
If you're cracked at building C++ systems software, on noncompete and bored, or looking to do something more meaningful than creating liquidity (you can tell most of our team is from HFT), reach out.
To apply: email met at carl@thundercompute.com and mention HN. I read every email.
Software hacker seeking hardware hacker to make custom robots for Magic: The Gathering automated storage and retrieval system to power an online e-commerce store (think CardKingdom competitor or eventual TCGPlayer competitor.) In terms of scale, the eventual target is >100k different _skus_, million items in inventory, tens of thousands picks per day. The industry is large; eBay bought TCGPlayer for $300M about 3 years ago.
I am looking for a mechanical/electrical/hardware generalist to complement my software expertise. Someone who knows how to integrate off the shelf parts into custom automation to solve problems. If fast iterations, direct connection with the project in use, autonomy and minimal bullshit overhead appeals to you then this could be a great fit. You are: someone who makes stuff and solves problems, is a clear communicator and fast study. You know how to challenge a requirement, source an off-the-shelf-part or design custom manufacturable part and when to do each. I don't really care where or when or what your degree is in if you have demonstrated driving things to completion and we vibe well enough.
We will use OnShape (license/seat will be provided) for collaboration and document management reasons. Much of what we need to build is integrating FUYU linear rails, Clearpath motors, pneumatics with some custom Send Cut Send / Xometry parts, 8020 frames, etc.
Pros: Small team / minimal overhead and wide scope. Clear guidance on what to build. Flexible-ish schedule (core hours 9-5 in office, flexibility for school breaks, etc.) Real problem with established market.
While I'm primarily looking for a contractor for now, I am open to the possibility of bringing the right person on full-time with equity if they are interested and invested in the space, but that is not a requirement and it probably makes sense to establish that after working together for a bit.
No recruiters or third parties, not able to sponsor at this time. Compensation dependent on experience.
Hiring process: resume/project review, vc chat < 1 hour, then paid 1-day work trial where we see if we fit.
If you're interested, send me an email - hiring@mulliganpost.com
Join us in pioneering the future of e-commerce search. 1M+ MAU growing rapidly. Large seed round raised from top-tier VCs and individuals with backgrounds from Google, Amazon, OpenAI, Stitch Fix, Whatnot, Stripe, and more.
We're a hard-working team of 10. We have an office in Jackson Square with a great view that we're looking to fill with other high-performance people!
Tech-wise, it's React/Typescript + Julia, if that's interesting (no worries if you haven't used it). We've also built our own graph and vector DB to cope with the scale, and the foundations of a neuro-symbolic AI agent that learns more about the world on every search!

We’re looking for someone who is (or can quickly become) strong in end-to-end LLMOps: building and optimizing LLM pipelines, managing inference performance, improving reliability, and supporting production AI features. You’ll work closely with our Staff Engineer and Data Engineer on a small, highly technical team.
We don’t have hard requirements around degrees or specific model frameworks - but you do need hands-on experience with LLMs, vector databases, embeddings, prompt optimization, and deploying/maintaining ML systems in production. Part of the process includes a practical take-home assignment (real-world, not leetcode), followed by technical conversations with engineering leadership.
We’re looking for someone who can think in systems, make good architectural decisions, and operate with a high level of ownership. Thrive is not a place where work is micromanaged - you’ll thrive here (pun intended) if you’re proactive, self-directed, and comfortable moving quickly without rigid structure. Happy to answer any questions here!

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.
On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem.

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, Material Sciences, and more.
This is an opportunity for senior engineers and product managers to join us, and contribute to shaping a deep-tech product from its earliest stage.
We’re hiring for the following openings:
* Program Synthesis Engineer
* Bayesian Software Engineer
* Senior Product Manager

We're building Cursor for doctors. At Vibrant, we've picked the expensive, high-touch, data-heavy subspecialties of functional, integrative, and longevity medicine, and we've created AI agents that reduce hours of clinical work to minutes.
We're a world-class team of health tech founders, AI builders, and clinicians from Meta, Stride Health, Peloton, and Hinge Health. In just five months, we've built notetaking/scribing, Clinical Decision Support, and some of the integrations a clinician needs to run their practice with Vibrant as their AI Operating System.
In the words of doctors using our product already in production: "I have goosebumps, this is really incredible. Very accurate." "Seeing the patient overview AI-generated summary come to life after placing a couple notes is AMAZING. I'm losing it over here."
Our stack: Typescript, React, NextJS, React Native, Expo, AI SDK, custom AI agents, RAG, tools, and agentic workflows.
It's still early days for us, and we're looking for folks who ship fast and are curious and resourceful. If that's you, shoot me an email at pedro [at] vibrantpractice.com or just book an intro with me: https://book.vimcal.com/p/pedro/quick-chat

I’ve built a SaaS product with PMF already solved and a clear roadmap. Competitor traction shows there’s plenty of room in the space, and I’m looking for marketers and growth hackers to help secure customers and drive growth.
You’d be a great fit if you:
- Know how to acquire early customers in B2B SaaS - Thrive on creative, low-cost growth tactics (organic + paid) - Enjoy working lean and iterating quickly
We’ll need to operate lean in the beginning, but once revenue starts flowing, there will be budget for paid channels and ads to help scale further.
Commission is VERY generous for the short term engagement.
I’m open to trialing potential partners on a commission basis, and if we’re a good fit and see results, I’m ready to discuss a strategic equity partnership or salary.

Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.
We've raised $42M (https://zed.dev/blog/sequoia-backs-zed) to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Our mission is to empower field-service companies to grow by modernizing and automating their business operations. Every company we work with has unrealized potentials — our task is to build the platform that empowers growth and helps them unlock opportunities.
Email: jobs [at] 40grid.com (no recruiters or agencies, please put HN in subject line, thanks).
We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Saildrone is the world's leading collector of ocean-related in situ data via uncrewed vehicle, above and below the sea surface. We work with navies across the world to deliver insights about waterways, contribute to safety of life at sea, and mitigate illegal fishing and trafficking. Additionally, we work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, or counting biomass to establish fishing quotas.
Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just announced a large partnership with Lockheed Martin[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand and secure our planet.
Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.
In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.

At Goblins, we're building America's favorite teacher, starting with K-12 math. We're live in thousands of classrooms for in-class assignments, extra practice, and homework. Students work on a whiteboard while our models analyze their work in real time and nudge them with questions that make them think. Teachers get instant visibility into how the class is doing, who needs help, and what to assign next.
We just raised our seed round and are backed by the Gates Foundation, giving us the ability to build something transformative in education.
Here's what you might work on:
- Create shareable "aha moment" videos from real student sessions.
Turn anonymized whiteboard work and Goblin–student dialogues into short videos or interactive replays that highlight the value of Goblins. Automatically identify the best moments, strip out sensitive data, and produce artifacts that teachers, parents, and districts want to watch and share.
- Rewrite our diffusion transformer real-time avatar stack.
Our Goblin avatars are already in production. Improve audio–motion sync, temporal coherence, and expressiveness, while cutting latency and cost so they run smoothly at 100k+ student scale.
- Extend continuous diagnostics to high-stakes like the SAT and ACT.
We track mastery against state standards with our spin on IRT. Extend this to SAT/ACT-style exams: infer score distributions from behavior, validate on real data, and compute minimal targeted practice that reliably moves predicted scores.
- Design uncheatable problem formats.
Generative AI can solve most traditional math problems and show fake work. Build formats where copying is harder than thinking: dynamic graphs, constructive proofs, counterexample generation, debugging flawed solutions, multi-step conceptual checks. Make them auto-gradable, resistant to copy-paste, and stable at scale.
- Build real-time instructional agents.
Detect underlying student misconceptions from their work and have an agent "drop in" only when needed. It should generate short, visual, 3blue1brown-style explanations tailored to the specific misunderstanding, and create diagrams, animations, and interactive examples that adapt as the student responds.
The role is based in our Williamsburg, Brooklyn office in NYC (on-site only). You'll join our tight-knit founding engineering team of 3—myself (the CTO) and two founding engineers with collective experience from Stanford, Stripe, Amazon, and X1.
As our third founding engineer, you'll have full ownership of critical projects and ship production systems that impact thousands of students and teachers in real classrooms within your first few weeks.
If this sounds fun, and you want to help inspire 1 billion kids to love to learn, email alp@goblinsapp.com :)
Company: we're a small startup (pre Series A) building a business-in-a-box solution for landscaping companies, initially targeting the US. It's a huge market with more than 700000 companies in the US alone but with very little good software. We're looking for a very experienced backend engineer (senior/staff level) capable of taking ownership and leading the development of entire systems.
We keep our infrastructure as simple as possible, so the entire backend is in Golang with Postgres+S3 as the data storage layer. And a bit of Terraform for the infrastructure.
We're NOT a standard "AI startup" doing LLM wrappers, but we do have our own computer vision AI that we use to produce models from satellite imagery. So if you're interested in working on unusual AI pipelines, we have plenty of work there too.
Our frontend is a React.Native app, and we're working towards having full feature-parity inside a regular webapp.
Experience:
* Go backend experience
* A lot of experience with distributed systems
* Designing robust APIs (we're using ConnectRPC)
* Ideally experience with offline apps and database synchronization
* The usual: infrastructure-as-code, Docker, Github actions, OpenTelemetry, etc.
Salary: $170-$210k and equity

please have the basic decency to send a simple acknowledgement or revert after receiving them.
This has happened repeatedly over the past few months after sending dozens of emails from these threads, sometimes 10+ at a time. Not getting even a basic response feels extremely disheartening.
I know it’s a tough time for everyone searching for a job, and we all understand if things are slow —
but a small confirmation like “Received, we’ll check” or “Not hiring anymore” takes 5 seconds and makes a world of difference.
Let’s be kinder to each other. It’s been a very hard year
I am not blaming anyone, I can imagine making >100k in India enables you to take care of your whole family. At the same time do you really expect companies to treat applicants with as much care when they have gone from ~100 applicants per job to several thousand?
1. The majority of application emails I received obviously had not read the job description. They applied with a resume that didn’t have any relevant experience or, if they had experience, didn’t explain it in the resume. If you’re applying to a job, send a resume that shows why your experience is good for the job you’re applying for.
2. Check your email. I would say that most of the people I responded to either never followed up or waited weeks to respond. Of those who scheduled calls, many were no shows. This no-show rate was higher on HN than for my other job postings.
3. Make it easy for the hiring manager to believe you’re a real person and you are who you say you are. This will make some people angry, but when hiring remote you get a lot of scam applicants, overemployed people, and I even know one friend whose company accidentally hired two North Korean people pretending to live in the US. Do yourself a favor and make it easy to believe you’re real. Spend 30 minutes making a LinkedIn profile and updating it right before your job search (and then never check the site again if you prefer). Make sure your resume states the same location you tell the hiring manager. Use the same phone number everywhere. Make it easy to verify past employment even if you have to do a little extra work. There are so many scam applicants that you can easily get filtered out if something looks a little bit off.
4. Do not submit an AI resume and AI application letter! Hiring managers see these all day long and can recognize them. Do not fall prey to the social media wisdom that nobody reads your resume or that you need to use AI to write it because AI will read it. These AI written resumes are exactly what all those scam applicants use and it makes you hard to differentiate.
I write all my responses by hand, that’s just how I like to do things. If it is going to take me longer to write the rejection than the applicant spent on the application, I’m not going to do it. It would be unmaintainable to keep up with, and it’s hard to feel that someone deserves a few minutes of my time because they copy pasted an email address (if that).
I can’t speak for everyone’s practices, but genuine applications with effort put in are met with the same level of effort in the response. I’ve interviewed dozens of people solely on their level of effort put into the application (as opposed to the content of their resume). I’d rather spend an hour interviewing a bad fit that cares than responding to 20 people who couldn’t even name the company they applied to.
I think those struggling would find better luck with quality over quantity wrt applications. It takes shockingly little to stand out from the flood of applications you get on here. Including things like the name of the company, why you’re interested, and why you’d be a good fit are exceedingly rare (and imho the bare minimum for an application). If you can convey even a modicum of excitement or competence, it basically guarantees you at least a response, if not an interview.
Also, I’ve never responded to an AI generated application. That is not a solution, as it’s impossible to tell whether you’ve even seen the job ad or just signed up for some service. If you’re a non-native speaker, don’t worry about grammatical errors. If you’re really concerned and must use it, disclose your use of it if you want any hopes of a response
Just my two cents from the other side of the conversation.
Please only post if you are actively filling a position and are committed to responding to applicants.Says a lot about the current state of hiring in the tech.
the amount of attention this thread is receiving is a death knell for the "Who is hiring" item
