Software Engineer, CDN Content

About the role

The CDN Content team is responsible for serving all content that flows through Vercel's global CDN — static assets, optimized images, incrementally regenerated pages, partially prerendered shells, and everything in between — to billions of requests for millions of developers. Our focus is performance: ensuring content is served globally as fast as possible. Caching plays a big role in making that happen, and the team operates a multi-tier caching architecture spanning in-process caches, regional cache services, and object storage across 20+ regions.

What You Will Do

• 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.
• 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.

About You

• 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.

Bonus If You

• Have experience with caching systems (CDNs, Redis/Memcached, application-level caches) at any scale.
• Have AWS experience, particularly S3 or ElastiCache.
• Have used Next.js or another modern web framework and understand rendering modes like SSR/SSG/ISR.
• Have experience with observability tooling (Datadog, Honeycomb, or similar).
• Have experience with Terraform or Kubernetes.
