Integrations Engineer

Runlayer • New York, NY

3d • Remote

About The Position

As an Integrations Engineer, you'll own Runlayer's coverage surface: making every AI client, agent framework, and MCP server work first-class through the control plane. Coverage is the product, so you'll own integrations end to end, from design and launch through monitoring and debugging, and catch breaks before customers do. This is a hands-on, high-ownership role, and you'll help shape how the integrations functions works as it grows.

Requirements

• 5+ years building integrations, SDKs, or developer-platform connectors, with strong opinions on partner API design.
• Expert-level OAuth 2.1: you've implemented authorization servers, token brokers, or complex multi-provider OAuth flows.
• Agent-ecosystem fluency: you've built or operated MCP servers and shipped on at least one agent framework, and can explain transports, tool schemas, and session lifecycle from experience.
• Strong TypeScript and Python.
• You've built integration test suites that run against real third-party APIs with auth.
• An operational mindset: you own systems in production, treat reliability as first-class, and can trace an issue from a customer report through logs and API responses to root cause.
• You've maintained a catalog or marketplace of third-party integrations, with versioning, deprecation, and migration patterns.
• AI-native workflow: you delegate real work to agents daily

Nice To Haves

• Contributions to the MCP spec or to an agent framework.
• Experience running or scaling a partner / integrations engineering function.
• Familiarity with enterprise identity (SSO, SCIM) and policy enforcement.

Responsibilities

• Own the full lifecycle of integrations: design, build, launch, monitor, and debug connectors across clients, agent frameworks, and MCP servers.
• Make every major AI client (Claude Code, Claude Desktop, Cursor, Codex, Copilot, and the long tail) work first-class through Runlayer, from auth to policy enforcement, hooks, and session extraction.
• Give agents built on any ADK (Claude Agent SDK, OpenAI Agents SDK, LangGraph, Google ADK, and whatever ships next) identity, governance, and observability, including agent accounts and attributing MCP calls to the agents that made them.
• Keep 50+ third-party MCP connectors reliable: catch upstream breaks and auth regressions before customers hit them, and guide admins safely through migrations (URL changes, stdio-to-deploy, forced re-auth, scope changes).
• Own reliability end to end: coverage smoke-tests on every release, monitoring, and fast debugging under real-time customer pressure.
• Build the OAuth broker (the TypeScript/Express service managing OAuth 2.1 flows for third-party servers) and the tooling that scaffolds, validates, and publishes new integrations with little manual work.
• Work cross-functionally with product, partnerships, and customers, and help shape how the integrations function grows.

Benefits

• Competitive salary and equity — compensation that reflects your expertise and customer-facing responsibilities.
• Paid time off — paid vacation, paid sick leave, and paid parental leave.
• Professional development — budget for conferences, courses, and certifications in AI, enterprise software, and customer success.
• Top-tier equipment — your choice of laptop and accessories to create your ideal work environment.
• Health benefits — comprehensive health, dental, and vision coverage.
• Customer interaction opportunities — work directly with innovative companies and see the immediate impact of your work.
