At JetBrains, code is our passion. Ever since we started, back in 2000, we have strived to make the strongest, most effective developer tools on earth. By automating routine checks and corrections, our tools speed up production, freeing developers to grow, discover, and create.
Our team works on Kotlin/Native, a compiler and runtime for the Kotlin language, which is based on the LLVM toolchain and supports a wide range of targets. A lot of attention is devoted to smooth interoperability, both direct (using C and Objective-C libraries from Kotlin) and reverse (using Kotlin libraries from C, Objective-C, and Swift).
Kotlin/Native plays a significant role in Kotlin Multiplatform (KMP), powering many iOS applications under the hood. The technology is used by well-known companies such as Google, Duolingo, X, and others.
We are now looking for a Senior Developer with general software engineering skills. We expect that you will be able to pick up new technologies as you go. Although it’d be great if you are already familiar with Kotlin or LLVM, it’s not a must.
As part of the team, you will:- Work on the Kotlin/Native toolchain.
- Improve the development experience with Kotlin/Native.
- Optimize compiler performance and generated code.
- Help design and implement new Kotlin features.
- Enjoy solving complex problems.
- Have at least three years of experience in commercial software development.
- Understand how compilers work and/or know static analysis techniques.
- Can design and write code that is easy to read and maintain.
- Can work well both independently and as part of a team.
- Know basic algorithms and data structures.
- Are ready to communicate with users and solve their problems.
- Know how to profile and optimize your code.
- Are eager to explore new technologies.
- Have previously programmed in Java, Kotlin, or other JVM languages.
- Are familiar with Clang, LLVM, or any other production-grade compiler.
- Have contributed to open-source projects or worked on your own projects.
- Love finding creative solutions to challenging technical problems.
- Have experience analyzing and improving application performance.
