Full-Stack Team Leader

We’re looking for a Senior Full-Stack Team Leader who loves shipping fast, owning big pieces of the stack, and building modern cloud services from the ground up.

Lead and mentor a small, high-impact full-stack team (backend, frontend, DBA, DevOps).
Build product-facing microservices and full-stack features in TypeScript.
Drive features end-to-end, from idea to production, and help define engineering standards across the board.
Keep our environments rock-solid — secure, observable, cost-efficient, and resilient.
Debug tricky production issues across both infrastructure and application layers.
Continuously improve how we build: CI/CD, DevOps, documentation, workflows, and everything in between.
