About the Role

We're building an AI-powered work assistant that lives where work already happens - in Slack and Teams, with a web app on the way. People interact with it like a teammate: it writes code, runs it, and ships real work back. We're one of the fastest-growing companies in the world right now, and this is a rare moment to own something real.

We're looking for a Product Engineer who makes products people love, not just ones that work. You've shipped end to end, you have taste, and you won't ship less than good.

What You'll Do

  • Ship user-facing product end to end - frontend to backend, idea to production, across Slack, Teams, and the incoming web app. The bar is something real users touch on day one, not a prototype

  • Own onboarding and time-to-value: from install to first real win in minutes

  • Own what happens after you ship - find where users stall, fix it yourself, and move activation and retention

  • Design how people stay in control: propose-and-approve flows that stop bad actions without burying users in confirmations; surfaces that make agent actions legible and easy to steer

  • Talk to users and shape the problem - you don't wait for a spec, you find the rough edge, decide what to build, and build it

  • Polish like it matters - the details that separate a tool people tolerate from one they recommend

  • Whatever needs building. Small team, large surface

Who You Are

  • You've shipped a real product that real people use, owned end to end - not a side project that never left localhost

  • Range: React component to API to deployment script in an afternoon. The frontend/backend divide was never useful to you

  • Product instinct: you use the product, talk to the people who rely on it, and have UX opinions your work shows - without someone handing you a design

  • You talk to users and own outcomes, not tickets. You shape the problem, cut scope when you should, and ship the thing that moves the metric

  • Speed, with the bar up - you ship today, not Thursday, and it's still good

  • Agentic coding is your daily workflow - you build with AI by default and you're faster because of it

  • Genuine drive - you build things because you can't not

The Bar

You ship to production every day. You have product taste and you defend it - you know when "it works" isn't done. You work backwards from the user, not forwards from the tech. This role doesn't work without agentic coding fluency: if it isn't already how you work, you'll be behind on day one.

Tech Stack

TypeScript/React on the frontend, Python on the backend and agents, Modal for infrastructure. The role leans product and moves across the whole stack. You don't need all of it coming in, but you need to learn fast.

Nice to Have

  • Founded something or been an early-stage builder

  • Design sensibility - you can make it look and feel right, not just function

  • Shipped something with real traction: users, revenue, downloads

  • Moved a real metric (activation, retention, conversion) with before-and-after to show it

  • Built with modern AI tooling and have opinions about it

How We Work

Small team, high trust, low process. Decisions are made by owners, not committees. You'll ship your first week and talk to users your first day. No alignment meetings or stakeholder syncs - we build things, see if they work, and iterate.

Compensation

Top-of-market salary + meaningful equity at an early stage.
