Jobbeschreibung

Do you look for hidden bugs, write clean test code, and love deep-diving into complex software behavior? Do you want to take ownership of quality for tools that millions of developers use every day? If you enjoy solving technical puzzles and expanding test automation as a peer to developers, this role is for you.

About JetBrains

We create intelligent software development tools for developers and teams. More than 15 million users, over 300,000 companies, and 88 of the Fortune Global Top 100 rely on our products to solve real, complex problems. Our mission is simple: make development teams more productive and AI adoptable at scale.

What you’ll do

The IntelliJ Kotlin Plugin team builds the core support for Kotlin within JetBrains IDEs, covering vital features like highlighting, refactorings, and advanced coding assistance. As the Kotlin ecosystem evolves, our tooling must remain robust, accurate, and performant. We are focusing on systematically expanding test coverage across both existing functionality and emerging areas.

In this role, you will influence the stability of core developer workflows. This is not a role where you just run through a static checklist. You will have the autonomy to spot automation opportunities, design maintainable test scenarios, and shape how we test highly complex developer tools. You will collaborate directly with developers, investigating tricky edge cases and preventing regressions before they reach our community.

Day to day, you will:

• Collaborate with developers on exploratory testing of new and modified IDE functionality.
• Investigate and pinpoint bugs, report findings in our tracker, and perform regression testing.
• Design maintainable test scenarios and decide which ones should be automated.
• Write and maintain automated tests in Kotlin to expand coverage of IDE functionality.
• Analyze existing test coverage, identify critical gaps, and help prioritize future automation efforts.
• Participate in product planning to assess technical risks and plan QA work for proposed changes.
• Improve test coverage for Kotlin-related functionality in IntelliJ IDEA Ultimate and other priority areas of Kotlin tooling.

What you’ll bring

• A strong sense of ownership and a desire to see complex problems through to resolution.
• Natural curiosity and a passion for exploring unfamiliar technical areas to find hidden issues.
• A genuine interest in programming languages, IDEs, and developer tools.
• A collaborative mindset, working closely with engineering peers to solve technical puzzles.
• A balanced approach to testing, valuing both deep exploratory manual testing and systematic automation.
• A habit of raising the bar, leaving codebases and systems cleaner than you found them.

What you’ll need

• The ability to read and write clean code to create test examples, investigate failures, and build automated tests.
• Proficiency in Kotlin, Java, or another object-oriented programming language.
• Experience designing test scenarios and deciding what should be automated versus tested manually.
• Experience working with bug trackers, version control, and continuous integration systems.
• Familiarity with Java technologies, frameworks, and build tools like Maven or Gradle.
• The ability to analyze complex technical behaviors, such as static analysis, compilers, or language tooling.

What success looks like

Success means earning the trust of your team through sound technical decisions and thorough context-driven testing. You will systematically reduce regressions by closing test gaps and identifying high-value automation opportunities early. Ultimately, you succeed when you leave the Kotlin plugin more stable and reliable, helping millions of software developers build their projects without friction.

• 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.
• Extra time off. More days to relax, recharge, and do the things you love.
• Medical insurance allowance. Enjoy peace of mind for you and your family
• Learning and development opportunities. Access to conferences, courses, and language classes.
• Relocation support. We help make your move as smooth and stress-free as possible.
• Language classes. Pick up the local language or sharpen your English skills.
• Fuel your day. Enjoy a hot meal or receive a lunch allowance on workdays.
• Mental health support. To help you feel your best, we provide easy access to professional mental health services.
• Sports benefit. Enjoy an on-site gym or sports club stipend.
• Internal events. Join company-wide celebrations and team gatherings.
