Senior Software Engineer, Partnerships & Integrations; -Source

Copilot Kit is the #1 open-source platform for building AI Copilots — intelligent agents designed to work with users inside of real applications. In our first two years, we’ve delivered the fastest growing Java script AI framework of all time, and built a vibrant community (40k+ Git Hub stars, millions of weekly installs, 10s of millions of copilot interactions, double-digit MoM growth), are already monetizing at the enterprise level, and are used by companies ranging from startups to Fortune 100s (including production usage by over 10% of Fortune 500s).

We’re emerging as the default for a critical part of the AI stack: the agent/user interaction layer. Copilot Kit brings agents out of demos and terminals and into production, through deep integrations with the leading AI infrastructure companies and hyper-scalers (including the leading AI/infra teams at Google, Microsoft, Amazon, Oracle, Lang Chain, Mastra, Pydantic, Agno, and others).

Our small, fast-moving team is building the agentic application platform that will define how user-interactive AI actually manifests in the real world. This is a unique opportunity to join as an early leader on one of the most complex and high-leverage surfaces in AI — with significant scope for technical, product, and leadership growth.

You'll own integrations between Copilot Kit, AG-UI, and the broader AI ecosystem—building and maintaining connections with leading agent frameworks (Lang Graph, Google's ADK, Mastra, etc.), model providers, and enterprise platforms.

This role requires both breadth and depth: rapidly understand new frameworks, identify the right integration patterns, and ship production-quality SDKs that tens of thousands of developers depend on. You'll work directly with partner engineering teams and represent Copilot Kit in technical collaborations across the AI infrastructure ecosystem.

For integrations work, an AI-native workflow matters even more. You'll need to rapidly understand new frameworks, prototype integration approaches, and iterate quickly across multiple codebases. You're fluent in AI-assisted development as your primary mode of working—directing AI to explore unfamiliar APIs, generate integration boilerplate, and accelerate context-switching. You evaluate outputs, catch failure modes, and course-correct in real time. You've shipped meaningful work this way, especially in integrations where breadth and speed matter as much as depth.

• Build and maintain integrations with agent frameworks and model providers, including AG-UI protocol adapters

• Design clean, idiomatic APIs that feel native to each framework while maintaining ecosystem consistency

• Own full integration lifecycle: research, prototyping, implementation, documentation, and maintenance

• Work directly with partner teams to coordinate releases, resolve compatibility issues, and influence roadmaps

• Create comprehensive examples and guides for rapid adoption

• Monitor ecosystem trends and identify high-value integration opportunities

• Track record building integrations, SDKs, or libraries that connect disparate systems

• Strong Type Script expertise (3+ years);
  Python proficiency is a plus

• Experience rapidly learning new frameworks and APIs (you have a system for this)

• Comfort working across multiple codebases and languages simultaneously

• AI-native workflow with demonstrated ability to leverage AI tools for exploring APIs and accelerating context-switching

• Clear communication skills for cross-team/cross-company collaboration

• High independence and ability to drive projects end-to-end
