We are looking for an experienced developer to help us shape the future of the Kotlin ecosystem.

• Create and maintain foundational libraries for Kotlin core primitives that are used by hundreds of thousands of developers
• Become an expert in specific domains of computer science and software engineering
• Be part of a design committee that decides how the Kotlin API should be shaped
• Participate in creating standard Kotlin tools, specifications and language features
• Possess JVM development experience down to the implementation details of the Java standard library
• Have a strong understanding of the domain you've been working with
• Be able to write design documents for complex systems with strong reasoning behind each trade‑off and technical decision
• Possess experience in performance engineering or API design

In general, if you see yourself reading a Unicode standard, exploring how five other languages transform strings to bytes, figuring out why some Oceania islands changed their timezone from
-10:00 to +14:00 and whether it should be expressed in the API of Kotlin timezones, optimizing interface hierarchy to be more JIT‑friendly and are not afraid of re‑iterating over documentation a multitude of times, you won't get bored in our team.
