Paymail | Engineer | REMOTE | Startup Equity Only

Paymail is an invoicing and money transferring service over email. Because it's alot easier to send $50 to email@example.org than to send it to a long series of digits representing a branch and account number. In a way Paymail is an internet native payments competitor to x402.org. I'm the founder and I'm on a mission to make every bank your email provider. I spent the last year working for a banking outsourcing company and it gave me some good insights into what's possible in the FinTech world. I'm currently searching for a React+Typescript developer with good design instincts to give a huge chunk of equity to and become a cofounder of the company working with a well written medium sized React+Typescript codebase that represents our product.

Startups are busy but to get the product to an MVP stage is not very far away at all so it would suit someone looking for a potentially profitable side hustle or on a full time basis as well.

Stack: Stalwart, React, Typescript, Python, Rust, Postgres

TypeSafe AI | Software Engineer | ONSITE (San Francisco) | Full-time

TypeSafe AI (https://typesafe.ai/) is a well-funded stealth mode company making a new class of AI models which enable a reliable way to embed composable intelligence into traditional software, founded by a co-author of ChatGPT/RLHF/GPT4 (answering the questions "If AI is so smart, why are we barely automating any work? Why does today's AI always need a human-in-the-loop?").

We're especially looking for people to join our Synthetic Data research team - no previous data experience needed (synthetic or otherwise). We need strong engineers who care deeply about the end use cases and whose instincts are to NOT trust LLMs blindly and look at the reality of their generations (much more investigator in the spectrum of investigator vs optimizer).

Coop (https://smart.coop.farm)| 2nd Founding Engineer | iOS Heavy Engineer | Hybrid onsite | Austin, TX | Full-time, Part-time

My name is AJ Forsythe and I'm the Founder / Chief Chicken Tender at Coop! We're an Austin TX based company on a mission to build the world’s largest decentralized food production network, starting with AI powered chicken Coops. We’ve been in the market for about 18 months and our customers are in 48 states and will generate about >10M eggs this year. It's insanely fun to work on and we have a shot at building a huge business in the connected urban farming space. If you’re big into computer vision, consumer products that are fun, and an awesome team we would love to chat. The Coop has an automatic door + cameras doing computer vision work (predator detection, egg alerts, remote health monitoring, etc). It's a super exciting time and are seeing directional product market fit which I'm thrilled about. Seriously go check out our website, it's a super fun + amazing product.

We’re a tight-knit team of 5 people with 15+ years of experience working together. We’ve been through YC, started and scaled multinational million-dollar businesses together, taking them from idea to acquisition by a Fortune 50 company. We’re gritty and passionate without taking ourselves too seriously - and we’re here to build something really exciting that helps people reconnect with their food and the planet. We're VC backed (call it $5M) by some of the world's best investors but we are a scrappy small team that moves fast. We have an absolutely fantastic CTO Ryan that I'm looking for his / our right hand person to work alongside with. I think the term full stack is overused but that's closest to what we're looking for. Also this really isn’t a traditional Eng role, I look at it as we’re a small growing team and you would be one of us working on a ton a cool projects on day 1. Also, we LOVE working with founders so if you've started a company before that's epic.

Oh also, I have a fun project where I want to make a water gun turret that uses our cameras to detect predators and allows you to aim and blast them. If you're into hacking robotics and gimbals etc, please reach out.

You can also reach out to me directly at: aj[at]coop.farm - Just email me your LinkedIn / GitHub / portfolio + why you think you'll be an awesome fit and I'll respond. Please don’t use GPT too much. This is my 3rd company (2 have exited) and I want to build the super solid core team and you might be the perfect fit for us and vice versa. Bwok Bwok! AJ

Mission: Build better culture & growth systems for companies that don’t have them. Then make them stick.

Role: Somewhere between product, customer success, and HR consulting. You won’t “manage HR internally.” You will operate as an embedded advisor across multiple companies, helping them design, run, and improve their people programs using our platform and AI tooling.

Company: We’re a SaaS company in the employee engagement space. Our customers are Heads of People, HRBPs, and founders who want to run better 360 reviews, engagement surveys, and feedback systems-but don’t have the time or expertise to do it properly. FeedbackPulse makes employee engagement simple with tools for creating meaningful surveys, gathering staff feedback, and building a better workplace culture. Our platform offers engagement surveys, performance reviews, and 360° feedback solutions that help companies address high turnover rates and disengaged workforces.

You: HR/PeopleOps experience, using AI tools like Claude Cowork daily, clear writing skills, self-directed, and results-oriented.

Our culture: Direct communication, focused deep work, clear work-life boundaries, and sustainable growth as a bootstrapped company.

Mention you are from HN in your application message.

Maiven is hiring software engineers. We are looking for highly skilled builders. While all roles require strong full-stack capabilities, one of these roles will lean heavily into data engineering infrastructure, and your experience should set you up to hit the ground sprinting.

The reality: we operate as an intense, early stage startup. Our 50+ hour work weeks are baseline. If you want a comfortable gig, this isn't it. If you have high agency, want massive ownership, and genuinely love the chaotic highs and lows of building from scratch, let's talk.
