Kotlin Open Source Project Seeks Talented Contributors

Major Kotlin Open Source Project Seeks Contributors: New Opportunities for Developers

The Kotlin ecosystem continues to grow actively, and one of the key open source projects developed in this language has announced a large-scale recruitment of contributors. We are talking about Kotlin Multiplatform (KMP) — a flagship initiative by JetBrains that allows writing cross-platform code for Android, iOS, Web, Desktop, and server-side. The project is in an active development stage and invites developers of all levels to join its creation.

Why is this important?

Kotlin Multiplatform is already used in production by thousands of companies, including Netflix, Twitter, and Pinterest. However, to achieve full maturity, the project needs more hands: specialists are needed to work on the compiler, standard library, IDE plugins, and build tools. Participating in such a project is not only a way to improve your skills but also an opportunity to influence the future of the entire platform.

What do contributors get?

• Work with cutting-edge technologies: Kotlin/Native, Kotlin/JS, compiler optimizations, and IR representation.
• Mentorship from JetBrains engineers: each newcomer is assigned an experienced mentor who helps navigate the codebase.
• Flexible schedule: you can contribute in your free time, without strict deadlines.
• Recognition in the community: top contributors receive merch, mentions in blogs, and invitations to conferences.
• Employment opportunities: JetBrains often hires active open source contributors as full-time employees.

What tasks need to be solved?

The project is looking for specialists to work in the following areas:

• Developing new features for Kotlin Multiplatform (e.g., support for new platforms).
• Optimizing compiler and runtime performance.
• Fixing bugs and writing tests.
• Documenting and improving developer experience.
• Porting existing libraries to KMP.

How to join?

To become a contributor, simply:

1. Explore the Kotlin repository on GitHub.
2. Choose an issue labeled "good first issue" or "help wanted".
3. Contact the team via Kotlin Slack (#contributors channel).
4. Make a pull request and go through code review.

For beginners, there is a detailed contribution guide.

What does this give the PythonLib community?

Although PythonLib is dedicated to Python, knowledge of Kotlin is becoming increasingly valuable for full-stack developers. Participating in such an open source project broadens your horizons, teaches you to work with compilers and low-level optimizations — skills that are also useful when developing in Python. Additionally, many tools for Python (e.g., Kivy) are actively exploring integration with Kotlin Multiplatform.
