About the role

As engineer #1, you will work directly with the founders to build the product and shape our culture. You’ll wear many hats and touch everything from AI systems, user-facing features, to backend infrastructure.

  • Talk to users often to deeply understand how to improve Floot's AI and UX (you can expect to spend 10-20% of your time on support)
  • Ship full-stack features and build the foundational building blocks that users will use to build their apps seamlessly (e.g. storage, payments, auth, etc)
  • Improve our AI runtime to handle edge cases and make our agentic system more reliable
  • Prompt engineeringand evals to improve AI output quality (for both function + design)
  • Build robust infrastructure for our end-to-end platform to power millions of production apps

Requirements

  • Strong full-stack experience with React, TypeScript, and Node.js: you've shipped production features end-to-end
  • Strong sense of ownership: you’re autonomous and own features from start to finish
  • Fast but thoughtful: you ship quickly without cutting corners on things that matter
  • Strong sense for UX and product polish: you believe that craft matters
