Senior Engineer (Platform)

Join our early-stage startup as a Senior Engineer (Platform). In this hands-on role, you'll design, build, and evolve our core backend services and platform infrastructure. You'll architect distributed backend systems, integrate third-party platforms, and shape our data architecture. You'll also raise the engineering bar by setting technical standards, mentoring engineers, and owning complex cross-team projects. Strong candidates should have deep, broad backend experience, fluency in TypeScript, Python, and Go, and infrastructure and DevOps depth.

Design, build, and evolve the core backend services and platform infrastructure that the rest of engineering depends on.
