About this role

We are looking for a Senior Full Stack Engineer with 4-8 years of experience to own and build net-new product areas at a high-growth AI startup transforming insurance operations. You'll join a 15-person team (10 in eng/prod) that's grown from $0 to $3M in revenue in just 15 months, building AI agents that handle complex insurance workflows across voice, chat, email, and SMS. This is a high-ownership role where you'll be building from scratch 80% of the time, specifically driving the company's new browser automation and document intelligence platform. You'll report directly to the CEO and work alongside a tight-knit, ambitious team in San Francisco.

  • Work cross-functionally with product and forward-deployed engineering teams, and selectively join customer meetings to demo features you've built
  • Shape technical decisions on architecture, tooling, and infrastructure as an early engineer at a company scaling fast
  • Help establish engineering best practices and mentor newer engineers as the team grows toward 30 people by year-end

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
