Job summary

Sandbar is seeking a strong generalist engineer in New York City to connect Stream to the software people use every day. You’ll own end-to-end integrations, shipping on real-time Python services alongside the founders and shaping how others build on Stream.

You’ll build reliable connections with OAuth, webhooks, and rate limits, while instrumenting integrations to catch breakages before users notice and contributing to the core backend and on-call rotations.

Qualifications

• 5+ years building software, with strong Python and comfort owning a live, real-time service.
• Have shipped third-party integrations in production: OAuth 2/OIDC, token refresh and revocation, webhooks, API versioning, and vendor quirks.
• Understand software architecture well enough to work with applications you didn't write.
• Have integrated tools into an LLM agent that real users depend on, and been accountable for actions completing.
• Hands-on MCP experience.

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.
