Ruby on Rails + TypeScript jobs

TypeScript is now the default expectation at most senior Rails + frontend roles, not a differentiator. Recent hirers visible in this collection include Stepful, StackAdapt, Spring Health, Tines, Pinwheel, and a long tail of product teams that adopted TS years ago and would no longer hire engineers without it. The interesting question on these roles is rarely "do you know TypeScript" — it's how you handle the API contract between Rails and TS, and how strict your typing discipline is in practice.
