Job summary

Vercel is seeking a Software Engineer to join the CDN Content team in San Francisco. You will work on ISR, PPR, and image optimization, building services in Go, Lua, and TypeScript across the serving path with production impact.

You will monitor production, contribute to observability, participate in on‑call rotations, and collaborate with Next.js and CI/CD teams. Remote-friendly in a hybrid setup; base salary in SF and equity helps shape total compensation.

Qualifications

• 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.
• 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.

Responsibilities

• 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.
