About the role

Key responsibilities & impact

Build and improve the services behind ISR, PPR, and image optimization — working in Go, Lua, and TypeScript across the serving path.
Execute well-defined projects independently, from implementation through safe rollout (feature flags, shadow modes, progressive deployment) and post-ship validation.
Monitor and maintain your work in production: build dashboards, add metrics and alerts, and develop ownership of what you ship.
Contribute to the team's observability and testing surface — the dashboards, logs views, and e2e test suites that keep a high-change system trustworthy.
Participate in the on-call rotation with support from senior engineers, and contribute to incident follow-ups that make the system more resilient.
Collaborate with teammates and partner teams (Next.js, CI/CD) through design discussions, code review, and pairing.

Requirements

What you’ll need

2+ years of experience building and operating backend services in production.
Proficiency in at least one of Go, TypeScript/Node.js, or a comparable systems language, and enthusiasm for working across a polyglot stack.
Solid understanding of HTTP and web fundamentals — caching headers, request/response lifecycle, what a proxy does.
You write code you're willing to operate: tested, instrumented, and documented.
Curious about how large-scale systems work, and motivated to dig into unfamiliar code and production data to figure things out.
A collaborative teammate who communicates clearly, asks good questions, and follows through reliably.
