Job description

About the Role

CI/CD is the beating heart of Vercel. Developers & agents alike create over 1 million builds per day on Vercel. Whether they’re previewing a new idea from v0 or shipping the next great thing to production, every customer builds. As a Software Engineer on the CI/CD team, you’ll build the infrastructure that powers all of these builds at scale. You’ll work on refining the reliability of the system, accelerate its performance, and transform how customers interact with builds on Vercel. This role blends product thinking with deep systems work – you’ll build features that serve both internal teams and Vercel’s global developer community. We’re looking for engineers excited to work on high‑scale systems, who love improving the developer experience, and who want to have a direct impact on how software gets shipped on the web.

Location: If you’re within a predetermined commuting distance of our London or Berlin office, the role includes in‑office anchor days on Monday, Tuesday, and Friday. If you’re located beyond that distance in the UK or Germany, the role is fully remote. For location‑specific details, please connect with our recruiting team.

What You Will Do

• Build and maintain our mission‑critical build system, and the micro‑services which power it.
• Engage and collaborate with open‑source project owners to improve the performance of their frameworks on Vercel, aligning Vercel’s commitment to giving back to the developer community.
• Participate in an on‑call rotation for the Vercel build pipeline.

Qualifications

• 6+ years of relevant software engineering experience.
• Practical experience building, running, and debugging distributed systems.
• Familiarity with containerisation and Linux systems.
• Strong proficiency in at least one of JavaScript/TypeScript/Go.
• Excellent problem‑solving and communication skills with an enthusiasm for digging into problems with unknown solutions.

Bonus

• Built and maintained CI/CD systems.
• Have UI/UX/product engineering experience.
