Retell AI is a voice AI platform for production phone agents, enabling enterprise call centers to deploy AI agents for handling real calls at scale. The Integrations Engineer will be responsible for building and shipping integrations that enhance Retell's presence within existing developer tools, ultimately driving user signups and engagement.
Responsibilities
- Build and ship MCP server integrations that put Retell inside AI-native workflows (ChatGPT, Claude, Cursor, etc.)
- Build and maintain connectors on N8N, Zapier, Make — own the full lifecycle from submission to listing optimization
- Create plug-and-play starter workflows that lower time-to-first-call for new signups
- Instrument the self-serve funnel: track which integrations drive signups, activation, and conversion
- Work with our PLG PMM to prioritize which integrations to build next based on user demand and distribution potential
- Own the developer onboarding experience for integration users — docs, quickstarts, error handling, sample repos
- Maintain and improve our public API surface as the primary consumer of it
Skills
- You've shipped production integrations on at least one major platform (Zapier, N8N, Slack App Directory, Salesforce AppExchange, etc.)
- You're a strong generalist engineer — comfortable across Node/Python, REST APIs, OAuth, webhooks, and whatever random auth scheme the next platform uses
- You think about integrations as distribution, not just technical plumbing. You care whether the listing converts, not just whether the connector works
- You move fast and ship without waiting for permission. At a 20-person company, this role has no spec to follow — you decide what to build
- Bonus: you've worked with voice/telephony APIs (Twilio, Vonage, Telnyx) or real-time media
