Location Type: IN_OFFICE

Employment Type: FULL_TIME

• 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

• 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
• Generalist range across backend, auth, client code, and agent logic; can take an open-ended problem to a shipped result without a spec
• Product sense for software that acts on someone’s behalf, including when the user isn’t looking at a screen
• Communicate precisely and make tradeoffs explicit

• Connector or plugin work at an AI product
• Browser automation (e.g. Playwright, Chrome DevTools Protocol)
• Integration security: scoped credentials, secret storage, prompt-injection defenses, audit logging
• Voice or multimodal assistant experience
• Developer documentation other engineers have built on

• Health, vision, and dental benefits
• Company-sponsored 401(k)
• Unlimited PTO and sick time
• Early stage equity
