QA Engineer (Kotlin Compiler Frontend)

We build intelligent tools for developers and development teams. More than 15 million developers and over 300,000 companies worldwide rely on our products to solve real, complex problems.

Our mission is simple: make development teams more productive and bring more joy to software development.

As part of the Kotlin Compiler team, you will search for existing and potential problems, working both independently and alongside other team members. You will be expected to show initiative and manage your tasks effectively. This role also requires a willingness to learn new things, and we have a large team of developers who are keen to support you by answering questions and explaining technical details.

• Do exploratory testing of new language functionality, as well as changes to existing functionality, working in tandem with a programmer.

• Test new language constructs.

• Search for and localize bugs, submitting the results to our issue tracker, and do regression testing for code fixes.

• Contribute to automated tests.

• Take part in planning, including for testing changes.

We understand that Compiler QAs are somewhat rare. Even if you don’t have specific Compiler QA experience, as long as you’re curious and eager to write and debug code, explore new things, and work with automation, this may be the right role for you. Here are some examples of the types of issues our QA Engineers regularly deal with. Take a look and see whether this type of work sparks your interest!

class C { fun foo() = "member" }
fun C.foo() = "ext"
println(C().foo())  // which foo() is called?

val t = (null as String?) ?: throw RuntimeException("x")
println(t.length)  // what's the type of t?

• Knowledge of Kotlin, both in general and with respect to specific features and how they interact. Knowledge of other programming languages would be a plus.
• Coding ability sufficient to create test examples and simple programs.
• The ability to master new programming languages and technologies.
• Experience working with IDEs, bug trackers, version control systems, and continuous integration systems.
