  • Experience designing or operating security-sensitive systems, with sound judgment about identity, authorization, credential handling, concurrency, and state management.

What You'll Be Doing

  • Evolve our implementation as the MCP specification changes, planning safe migrations for existing customers and integrations.
  • Design and review authentication and authorization flows involving Cloudflare Access, OAuth, identity, credential handling, and delegated access to upstream services.
  • Improve the reliability and scalability of multi-tenant systems built on the Cloudflare Developer Platform, using production data to identify and prioritize work.
  • Strengthen observability through structured logs, metrics, traces, dashboards, and actionable alerts; participate in production support and incident response.
  • Lead investigations of complex customer issues across services and teams, identify root causes, and drive fixes that prevent recurrence.
  • Review designs and code, mentor engineers, and raise the quality of testing, deployment, and operational practices on the team.
