Skills
- • Ships full-stack. Frontend, backend, schema, tests — handoffs aren't the model
- • Treats specs as the product. Decomposition into clear, scoped, runnable work is the highest-leverage skill on this team
- • AI in the daily flow. You don't wait for permission to use Cursor or Claude Code — you already do, and you push back when conventions need updating
- • Talks to users. Not "reads tickets" — actually joins customer calls and reads support threads
- • Owns past launch. If the customer experience around your work is broken, that's still on you
- • Shipped production systems and user- facing features end- to end within the last 1- 2 years
- • Backend expertise in an MVC framework (Ruby on Rails, Django, or Spring Boot)
- • 5+ years of experience as a backend- leaning full- stack engineer

- • Actively uses AI tooling in day- to- day workflows
- • Must be available for quarterly off- sites in Austin
- • Worked at a company with a high iteration speed on new products (startups < 100 people strongly preferred)
