About this role

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.

  • Strong base salary. We offer competitive pay that reflects your skills and experience.
  • Flexible work location. Enjoy the freedom to work from home or from the office.
  • Remote work. Spend up to 30 days per year working remotely from abroad.
