What you’ll do

As part of the Kotlin Compiler team, you’ll take ownership of the central pipeline that connects the compiler’s frontend with multiple backends. This is deep, technical work that directly influences how Kotlin code is transformed, validated, and optimized. You’ll make architectural decisions that improve compiler performance and memory usage without sacrificing backward compatibility. Working closely with other Kotlin teams, your efforts will shape the evolution of the language and improve the daily experience for Kotlin developers worldwide.

Day to day, you will:

What success looks like

In your first few months, you’ll dive into the compiler's central pipeline and start taking ownership of specific lowering passes and bug fixes. Over time, you’ll be making significant architectural contributions that measurably improve compiler performance and memory usage. Success means earning the trust of your team through clear communication, well-reasoned decisions, and code that leaves the Kotlin compiler cleaner and more robust than you found it.
