Senior Software Engineer, Partnerships & Integrations (Open-Source)

The Role

You'll own the deep integrations between CopilotKit & AG-UI and the broader agentic stack -- and keep our position as the default choice for connecting any agent to user-facing surfaces.

You'll collaborate on a daily basis with some of the most important teams on some of the world's most important companies, including the leading AI teams at Google, Microsoft, Amazon, Oracle, as well as leading teams as Langchain, Mastra, Pydantic, Agno, AG2, Llamaindex, and others.

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 CopilotKit in technical collaborations across the AI infrastructure ecosystem.

We're Looking for Pilots, Not Just Mechanics

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.

What You'll Do

• 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

Requirements

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