Anthropic's London office is hiring backend and infrastructure engineers to help build and scale the systems behind Claude. You'll work across areas like distributed systems, reliability, and developer tooling, collaborating closely with research teams on production infrastructure that serves millions of requests. Anthropic sponsors UK Skilled Worker visas for international hires and retains an immigration lawyer to support the process end to end.
What you'll do: design and operate large-scale distributed systems; partner with research and product teams to ship infrastructure that supports frontier model deployment; participate in on-call rotations and drive reliability improvements.
What we're looking for: strong software engineering fundamentals, experience with distributed systems or infrastructure at scale, and genuine interest in AI safety. No specific language/framework is required — Anthropic hires generalists who can pick up what's needed.
