Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Software Engineer, Open Source - **Company:** CrewAi Inc. - **Location:** San Francisco, CA, United States - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), Code Review, Github, Python (Programming Language), Open Source Technology, Management of Software Versions, Web Services, Large Language Models, Multi-Agent Systems, Pytest, Code Testing, Ripple (payment Protocol), Api Design, Discord - **Published:** June 29, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=f646958f9b9b673e ## About the Role Do you have experience in Web services design?, * 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. ## Description 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. ## Related Videos - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Craftsmanship in the Age of Agents](https://www.wearedevelopers.com/videos/100106-craftsmanship-in-the-age-of-agents) - [pytest: Simple, rapid and fun testing with Python](https://www.wearedevelopers.com/videos/213-pytest-simple-rapid-and-fun-testing-with-python) - [Developer Marketing](https://www.wearedevelopers.com/videos/1049-developer-marketing) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) - [Automagic Configuration in Python](https://www.wearedevelopers.com/videos/363-automagic-configuration-in-python) ## Related Articles - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [What is Agentic Programming and Why Should Developers Care?](https://www.wearedevelopers.com/magazine/625-what-is-agentic-programming-and-why-should-developers-care) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers)
