Our mission on the Connectivity team is to make Claude the most connected AI. As agents take on more real-world work, we're taking a leading role in defining how they get access to external systems — safely, with the right permissions, and in ways enterprises can trust. We ship for claude.ai, Claude Code, Cowork, and the API. We own the MCP proxy that routes every tool call and the OAuth and token management that keeps connections authenticated. We're also core contributors to the MCP spec — now an open standard under the Linux Foundation — and maintain the official Python and TypeScript SDKs. We're looking for an experienced engineering leader to lead a team of Connectivity engineers based in London. The Connectivity team spans San Francisco and London, and you'll work closely with engineering leadership and partner teams in San Francisco to set direction and deliver together across both sites. You'll lead a team working on problems where reliability and enterprise trust are the bar: token refresh at scale, admin controls that let IT govern what agents can do, and proxy infrastructure that stays up when partner servers don't.

In this role, you will be responsible for making Fireworks the go-to platform for building, fine-tuning, and serving frontier open models in production. This position requires a dual focus: you must be a hands-on engineer who ships code and understands technical nuances, and a public technical communicator who can clearly articulate complex topics through writing, speaking, and community engagement. You will be at the forefront of a rapidly evolving field, consistently staying ahead of new model releases and making it look repeatable rather than heroic. As one of the first advocates on the team, you will help set the standards for content, launch responses, and team presence.
