## About JetBrains

JetBrains is a cutting-edge software vendor specializing in the creation of intelligent development tools, including IntelliJ IDEA – the leading Java IDE, and the Kotlin programming language.

## About the role

###### 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.
