Staff+ Software Engineer, Platform Connectivity

Visa sponsorship: available – as stated by Anthropic on their careers website (Skilled Worker visa).

Join Anthropic’s Connectivity team as a Staff+ Software Engineer, working from London or San Francisco. The team builds services that connect Claude products to external systems, with a focus on secure access, enterprise controls and dependable infrastructure. You’ll collaborate with partner teams across Anthropic and contribute to technology used across claude.ai, Claude Code, Cowork and the API.

The role combines technical leadership with hands-on engineering. You’ll shape complex projects, make architectural decisions and help develop the infrastructure and standards that let agents use external tools safely and reliably.

What you'll do:

• Design, build and operate the MCP proxy and systems for OAuth and token management.
• Lead reliability work, including service objectives, on-call, incident response and postmortems.
• Develop permissions and administrative controls for enterprise customers.
• Contribute to the MCP specification and official Python and TypeScript SDKs.
• Scope multi-month projects, build alignment across teams and turn uncertain goals into shipped work.

What they're looking for:

• Backend or platform engineering experience and familiarity with AI tools in software development.
• Experience running distributed production systems, including reliability, observability and incident response.
• A product-minded approach, with ownership from design through deployment and ongoing improvement.
• Independent technical judgement, comfort with ambiguity and strong cross-team communication.
