Software Engineer, Open Source
About CrewAI
CrewAI is the leading framework and enterprise platform for building and orchestrating multi-agent AI systems. The open-source framework is a lean, fast Python library that has grown to 53k+ GitHub stars, 7.4k+ forks, and 100k+ developers certified through our community courses. It is rapidly becoming the standard for production-grade agentic automation powering hundreds of millions of agentic executions a month. This role is about building that framework in the open.
The Role
You'll be a core maintainer of the CrewAI open-source framework: the Crews and Flows APIs that hundreds of thousands of developers build on. This is engineering done in public. Your design decisions, code reviews, and API choices are visible to a large community and ripple out to everyone building on the platform.
You'll balance velocity with the long-term stewardship a widely adopted open-source project demands, and you'll treat developer experience as a first-class product.
What You'll Do
- Design, build, and maintain core framework capabilities: agent orchestration, agent harness, Flows, task execution, tools, memory, MCP, A2A, and the public APIs developers depend on.
- Own the contributor experience: triage and review community PRs and issues, mentor contributors, and keep the bar high without killing momentum.
- Make and document API and DX decisions with backward compatibility and migration paths in mind. Changes here
