What is an open source developer?

An Open Source Developer is a software professional who creates, maintains, or contributes to software projects whose source code is freely available to the public. These developers collaborate with others in online communities, often working on projects hosted on platforms like GitHub or GitLab. Their work involves writing code, fixing bugs, reviewing pull requests, and documenting software. Open Source Developers help improve software that anyone can use, modify, or distribute, fostering innovation and collective problem-solving.

What does an open source developer do?

As an open source developer, you work with open source code, tweaking, improving, and building upon it to create new software for an organization. Your duties vary depending on the position, but they can include using your knowledge of various open source coding systems and software to code new programs and applications, troubleshooting and debugging software, and tracking and reporting issues. Your responsibilities also include researching and learning about current and new standards for the coding languages with which you work. Most open source developers have skills and expertise in multiple programming languages, but many organizations are willing to train quick learners on each project.

What are the key skills and qualifications needed to thrive as an open source developer, and why are they important?

To thrive as an Open Source Developer, you need strong programming skills, familiarity with version control systems like Git, and experience contributing to or maintaining open source projects. Proficiency with platforms such as GitHub, bug tracking systems, and knowledge of relevant programming languages (e.g., Python, JavaScript) are typically required. Excellent communication, collaboration, and self-motivation are crucial soft skills, as much of the work involves distributed teams and community interaction. These skills ensure effective project contributions, sustained community engagement, and the successful growth of open source initiatives.

How does an open source developer typically collaborate with a global, distributed team?

Open Source Developers often work with contributors from around the world, which means collaboration takes place primarily through online platforms such as GitHub, mailing lists, and chat tools like Slack or Discord. Communication is usually asynchronous due to time zone differences, so clear documentation and issue tracking are essential. Developers regularly review and comment on each other's code, participate in discussions about project direction, and sometimes join virtual meetings or code sprints. This environment encourages learning from diverse perspectives and requires strong written communication and self-motivation.

What is the difference between Open Source Developer vs Software Engineer?

AspectOpen Source DeveloperSoftware Engineer
Required CredentialsTypically a bachelor's degree in CS or related field; strong coding skillsUsually a bachelor's or higher in CS or related field; programming proficiency
Work EnvironmentCollaborative open source communities, remote or distributed teamsCorporate or organizational settings, often in-office or remote
Employer & Industry UsageOpen source projects, tech companies, startupsTech firms, software companies, enterprises
Common Search & ComparisonOften compared for coding skills and community involvementCompared for project management and product development roles

Open Source Developers focus on contributing to publicly available projects, often working in collaborative communities. Software Engineers design, develop, and maintain software products within organizations. While both require programming skills and a background in computer science, Open Source Developers emphasize community collaboration and open contributions, whereas Software Engineers typically work within structured teams on proprietary or client projects.

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.
What We're Looking For
  • 7 plus years of 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.

We are unable to provide immigration sponsorship for this role. Applicants must have existing authorization to work in the U.S.
