Job Description

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 affect a very large installed base.
Uphold engineering quality in the open: clean, well-tested Python, strong typing, and green CI on every change.
Write and improve documentation, examples, and guides that help developers succeed quickly.
Partner with runtime and platform engineers to keep the OSS-to-enterprise boundary coherent, and reconcile versioning so framework changes do not break downstream enterprise consumers.
Engage the community directly through GitHub Discussions, forums, Discord, and other channels, turning real usage and feedback into roadmap signal.

Requirements

What We're Looking For

Strong Python engineering background, with a track record of shipping and maintaining library or framework code, not just application code.
Genuine care for API design and developer experience. You've felt the difference between an API that's pleasant and one that isn't, and you can articulate why.
Experience contributing to or maintaining open-source projects: reviewing external PRs, managing issue backlogs, and communicating decisions in public.
Familiarity with the modern Python toolchain: uv, pytest, type hints, pre-commit, and well-tested code.
Working knowledge of LLMs and agent concepts, or the appetite and ability to come up to speed fast.
Comfort with the pace, ambiguity, and public feedback loops of an early-stage, high-growth environment.
