Senior Fullstack Developer

Salary Competitive

You will build and improve the Odins.ai platform. That means designing and shipping product features, keeping the system healthy, and making sure what we build stays simple and reliable as we grow. You’ll work where the impact is highest, whether that’s frontend, backend, or the glue between. You’ll work closely with and report directly to our CTO Stephan.


How we work

 No meetings for meetings' sake. Maximum quiet time to build.

  •   6-month alignment on company direction

  •   2-week cycles with light prioritization, just enough planning to start

  •   No standups, you're trusted to run with tasks and share progress when useful

  •   Bugs get fixed immediately, not added to a backlog

  •   Day-to-day: coding, designing, problem-solving, improving the platform with devs and data scientists

  •   5 min max to set up local env and start working
