About this role

Sandbar is hiring a Senior/Staff Software Engineer to connect its Stream product with the software people already use. The role owns integrations end to end, including agent tools, production MCP servers and clients, reliability, instrumentation, and contributing to the core backend and its on-call rotation.

Responsibilities:

Build integrations between Stream and the apps, services, and AI tools people already use
Design how tools plug into Stream’s agent: tool definitions, result shaping, confirmation, and context passing
Own the integration layer end to end: OAuth and token lifecycle, least-privilege scopes, webhooks, rate limits, retries, and real-world failure modes
Build and operate MCP servers and clients in production
Work out reliable integrations for software without clean APIs
Instrument every integration so breakage is caught before users notice
Carry a share of the core backend and its on-call rotation
