AI Engineer owning Brex's MCP Apps across OpenAI, Claude, and Slack — a product role disguised as infrastructure
Brex is hiring an AI Engineer to be the technical owner of its external AI ecosystem — MCP Apps and integrations that let customers interact with Brex through third-party assistants like OpenAI, Claude, and Slack. The JD explicitly frames this as 'a product role disguised as infrastructure,' measured by real usage and customer trust rather than integrations shipped, with heavy emphasis on secure cross-boundary identity (OAuth, RBAC) and resilience against unpredictable third-party platforms.
