Integrations Engineer

What Retell does

Retell is the voice AI platform for production phone agents. Enterprise call centers use us to deploy AI agents that handle real calls — inbound and outbound — at scale. 50M+ conversations/month. YC-backed. ~20 people.

What this role is

You're the person who makes Retell show up everywhere developers and ops teams already work.

Today, someone building a voice AI agent has to come find us. Your job is to flip that — make Retell appear inside the tools they're already using. ChatGPT, N8N, Zapier, Make, LangChain, CrewAI, Google Sheets, HubSpot, Salesforce. When someone drags a node, browses a template, or searches an app directory, Retell is there.

This is not a maintenance role. You're building the connectors, integrations, and developer experiences that become Retell's primary self-serve distribution channel. Every integration you ship is a new acquisition surface.

What you'll actually do

• 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

What makes someone great at this

• 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

What this is not

• This is not a backend infrastructure role. You won't be building Retell's core platform.
• This is not DevRel. You won't be on stage or writing blog posts (though you might write docs).
• This is not a "build it and hand it off" role. You own your integrations end-to-end, including whether they actually drive signups.
