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

As part of our team, you will:

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

Preferable:

JVM development experience down to the implementation details of the Java standard library

Strong understanding of the domain you've been working with

Ability to write design documents for complex systems with strong reasoning behind each trade-off and technical decision

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 is not afraid of re-iterating over documentation a multitude of times, you won't get bored in our team.
