fake opening.

you are looking for over a year and I know for a fact you rejected multiple engineers with 10+ years of experience after only seeing the CV without a single interview

Applied last month as I was moving to Amsterdam and found it interesting they were advertising here. 10 yoe, currently at Google, no Go and no streaming experience, got rejected without interviewing, thought I was lacking the proper experience, thanks for bringing this to our attention!

actually we're hiring faster than ever before. we have hired 10 engineers each quarter the last 2 quarters, and will keep that pace for the next 3.

and some of the hires we've made have never even used Go before.

Why’d they put up fake roles though?

I have no thoughts on whether it's actually fake, but it can be to appear financially healthy / boost company image, to gather resumes, to gather information about the job market, to comply with internal policies that say jobs most be posted externally even when planning to promote internally, etc.

This was already posted as: https://news.ycombinator.com/item?id=43243228

Please don't post the same job ad more than once.

FYI, Your website (https://getstream.io/) is broken :-)

Layer | Founding Eng | San Francisco In-Person Only | Full-Time

We believe SMBs are the backbone of American society and small business ownership is the best path to wealth creation and economic mobility for many Americans. We're trying to dramatically lower the activation energy in just one of the major hurdles for aspiring small business owners: accounting and bookkeeping.

Our approach is working! We embed directly within an SMB's primary business platform, manage all the data syncing & reconciliation for them, and have real humans (with real AI tooling) handling their books. We do this at ~half the cost of existing bookkeeping services and it's still profitable for us because we're saving so much time with our data access + AI.

Adoption is taking off faster even faster than we hoped and we need to grow the team! We're a team of 5 who like working with a high ownership and high throughput collaboration. We have serious technical challenges across scaling systems, data modeling, and building AI-driven automations of tedious tasks.

We want teammates who love learning and want to be involved in company building from the ground up - even if you aren't familiar with accounting or our tech stack. We have tier-1 investors, thousands of SMBs on the platform, and revenue has 10x'd in the last 6 months - it's a very good time to join us.

We're now undertaking HEROS v2, where there's a couple of very exciting challenges: How can GenAI be a 1-1 tutor during an hour of education. Can we keep the cost of the hour under 1 INR. Agentic workflows, vector-db/RAGs, finetuning and more techniques will be used.Interested in this challenge?

We're a team of deep technophiles, who are passionate about the transformation of education happening. We're partnered with over 2 dozen universities in India, and expanding overseas this year, growing 4-5X, year on year. And we've done all of this in a bootstrapped, default alive way.

This role would be one-off senior roles, working closely with head of engineer, and the co-founders in exploring and extending the edges of GenAI in education. Please send me an email note via my first name @kalvium.com if this sounds like something you'd like to take on, with evidence of work you've done with GenAI.

Shortwave | Onsite in SF | Full-time | shortwave.com

We’re building the [“strong form”](https://www.youtube.com/watch?v=2ZpJXHiPwtQ&t=498s) AI agent app for business communications. We’re focusing on email initially, as it’s (1) ubiquitous (2) open and (3) has a diverse set of valuable business data. In the future we plan to expand beyond email to include all essential business communications tools, including Slack, Teams, CRMs, document platforms, project management tools, and so on.

Most people’s experience with AI today involves copy & pasting content back and forth from ChatGPT. Not only is this a terrible UX — it severely limits the transformative potential of AI.

Our goal is to unlock 10x (or greater) productivity gains for the average business user by bringing cutting edge AI together with their business communications in a single app designed for effective human-AI collaboration. With Shortwave, users can give the AI access to all of their data and then allow it to take action while still maintaining total control over its output.

I previously founded Firebase and sold it to Google. This time we're taking it to IPO :)

Hiring for multiple engineering roles. See full listings here: https://shortwave.notion.site/Open-Positions-at-Shortwave-1a...

Neon | New York, San Francisco | Full-Time | Onsite

There’s a massive transition happening in the video games industry right now. Gaming has become a full-blown cultural movement, and many fail to appreciate how it has already become the dominant form of leisure and entertainment for an entire generation.

But as culture has evolved, technology has advanced, and more people have gravitated toward games, the industry incumbents that run the show haven’t kept up. Our big bet is that by empowering game creators with better technology, we'll make the entire ecosystem more welcoming, connected, efficient, creative, and fun for all.

We’re an early stage startup backed by Thrive Capital, Griffin Gaming Partners, Ribbit Capital and a16z's inaugural SPEEDRUN class. Our mission is to help game creators achieve independence by building the tools they need to start, run, and scale their businesses.

Project Healthy Minds (startupy mental health nonprofit) | Full-time | NYC | 5d/week in-office

We're looking for someone to lead our small-but-growing engineering team at our Hudson Yards office. There are about 10 full-timers in the office, with more members being added to the product and engineering teams this year. I'm leading product and the search for this role.

This is a unique opportunity – we're building a comprehensive dataset of mental health services and outcomes while prioritizing user privacy. As a nonprofit, we have no incentive to monetize user data. Instead, we're focused on two things: 1) helping people access care across the full treatment spectrum through our screening process (as developed with our clinical advisory committee), and 2) understanding outcomes by collecting anonymized outcome data to understand what actually works in mental healthcare - something that surprisingly doesn't exist yet at scale.

Our goal is to simultaneously solve the discovery problem for people seeking care while building the dataset needed to improve mental healthcare quality and accessibility.

Camber is working to improve the messy financial infrastructure for US Healthcare. We've built an automated end-to-end insurance billing system for recurring care, starting with Autism clinics. It’s a product that clinicians need and love.

We automate and abstract the tedious, manual, repetitive work that goes into the administrative duties of running a clinic, so that clinicians can do what they do best — providing care.

It starts with ingesting clinic data, and then create, validates, and submits claims to insurance providers across the country. If claims need corrections or appeals, most of the time we can handle those automatically or our CX and Operations team use our in-house internal tools. We also handle patient invoicing for co-pays, co-insurance, and deductibles (we never send anything to collections). We track money movement on a unified ledger and reconcile transactions with clinics' bank accounts.

There is so much more to build. If you're interested in scaling data pipelines, programmable rules engines, AI, data science, delightful products for small clinics, processing billions of dollars in money movement or solving the unsexy problems that make this country's healthcare broken, come join us!

We are a team of ~40 with strong product market fit. You’ll be working with an engineering leadership team from AWS and Stripe to get clinicians back to work delivering care for kids.

Squint | In person at our vibrant SF office 5x/week | Squint is a mobile app that uses AI and AR to automate data entry, generate custom procedures, and make every operator an expert. | squint.ai/careers

The U.S. manufacturing industry, worth $7 trillion, is growing rapidly but faces challenges in workforce turnover and management. Adopting technology is essential for improving training, efficiency, and scalability, yet the sector's tech landscape is still lacking.

Enter Squint. Squint makes it easy to capture expert knowledge, unlock operator performance, and analyze production insights. Manufacturing leaders use Squint to reduce downtime and increase quality – all on a platform operators love.

The best part is, this is just the beginning. We believe our solution can extend beyond manufacturing, and soon, we’ll empower workforces in industries like Energy, Healthcare, Hospitality, and more. Our mission is to accelerate human potential by bringing digital knowledge into the real world.

https://center.app | Center Pixel, Inc | Engineering | Full-time | Palo Alto, CA & Remote | 100k+ and up (we are flexible on salary since we're venture-backed and still a 4-person team) We build web3 developer tools and are most focused on solving the "schlep" types of problems that every team ends up building in house but shouldn't have to.

Building stuff in crypto today is really hard. Imagine if you wanted to put up a personal website and all you had to do was start by breaking ground to build a data center. Your personal page probably would not be that good, would it? Small teams can only focus on so many things; we want them to use center so they can focus on the details that truly matter and make products beautiful.

We want to eliminate all of these annoying, cumbersome, expensive problems that devs face so that they can build incredible user experiences that help people flourish and rise to the level of their ambition, without having to think about if their nodes are online or if their indexer is missing any data.

We started about 3 years ago and have finally started to find product market fit. We're looking to scale the engineering team so that we can finally bring our products to market.

Our investors include Founders Fund, Thrive Capital, SV Angel, @balajis, and many more incredible folks who have taken a chance on us; it's been my mission for the last 3+ years to make sure that everyone involved in this venture does phenomenally well.

Stealth Startup | [email protected] | Member of Technical Staff | Alamo Square, San Francisco, CA (ONSITE) | Full Time

We have been quietly building a new type of general frontier model since mid 2024. We are reinventing the entire LLM stack for real work, focused on reliability and decision-making. We are well funded with a small and fast moving team previously from OpenAI, Google Brain, Meta and Scale.

Please check out our website: hypesafe.ai

If you are interested, please include the following in your email (to [email protected]):

- Your resume + GitHub + LinkedIn

- What are some of your previous experiences that you feel proud to share?

- What do you think is the biggest bottleneck from LLMs automating more work? (Bonus points: go deeper than just “reliability”)

- If LLMs actually were reliable, which industries would you be the most excited to disrupt?

- What are you unusually good at? Tell us about something impactful that you made and loved making – feel free to brag a little ( :) ). What challenges/obstacles did you overcome, and how did you choose the solutions or approach you did? In an ideal world, how would you want to apply your unique talents to your next role?

Tetmon | QA Automation Engineer | Remote | Full-time https://www.tetmon.com/

Flexible hours, minimal meetings, fully remote

Tech: TypeScript, Python, Nix/NixOS

We have a suite of end-to-end tests that each spin up a virtual network from scratch to test our application. This test suite gates our automated release process and has been critical in allowing us to ship updates to users quickly and confidently. We'd like to expand it further and are looking for someone who cares about automation and correctness and can help us greatly expand what we test.

Part of the tests are written in Python (since that's what the NixOS test infrastructure provides) and part of the tests are written in TypeScript (the parts that drive a headless web browser). We developed our own convenience library on top of Puppeteer that make tests easier to write and more reliable than Puppeteer, Playwright, or Taiko (all of which we used previously). The tests can run locally (on Linux/MacOS development machines) and they run automatically on push to our build servers. The build servers are modern bare metal servers with Ampere and AMD CPUs with enough RAM to run dozens of test networks in parallel.

We have a simple review/interview/hiring process and low employee turnover.
