Staff Backend Engineer (Rails)
Tread, San Francisco +1
The role
We're hiring backend engineers to own our systems end-to-end — the data models, workflows, and APIs behind dispatch, ticketing, settlements, and integrations. You'll work with frontend, mobile, product, and our Forward Deployed Engineers, and you'll have meaningful input on how the system should behave for scalability and performance.
Our code has been ~100% AI-generated since March 2026. It's changed how the team works. We're building the software factory that turns customer, PM, and engineering input into safe deployable code. We expect the engineering team to be spinning up agents and managing the output rather than writing code by hand. While AI generates code here, engineers own the architecture, invariants, tests, review, security, and production behavior of everything we ship.
