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.
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.
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:
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.

JetBrains runs a Flexible Hybrid model, so most roles are tied to one of its 15 offices across Europe (including Amsterdam, Prague, Munich, Berlin, Belgrade, Warsaw, Madrid, London, and Cyprus), the Americas (Foster City, Marlton, and Waltham), and Shanghai. Even roles posted as remote are usually locked to a specific country, so check the location listed on a job before applying.
No. JetBrains hires across engineering, design, UX research, marketing, sales, and operations, and its careers page is explicit that you do not have to write code to be a match. Every hire, technical or not, is asked to complete a test assignment, which is how the team sees the actual skills a role needs in action.
Alongside hybrid flexibility and up to 30 days a year working abroad, JetBrains provides in-office meals, snacks, and drinks, a gym subsidy, a learning and development budget for conferences, books, and courses, and a top-spec equipment setup. Health, dental, vision, mental-health support, pension, and parental leave are included, though the exact coverage depends on the country you are based in.
It runs in stages: an application with a CV and short cover letter, an application review, a recruiter call, and a team interview. You are then given a test assignment, for any role and not just engineering, which can usually be done from home. Potential teammates review it, followed by a final interview and a reference check with three contacts before a decision is made.
JetBrains looks for people who raise the standard around them, care about why the work matters, and are comfortable owning decisions without close supervision. Having stayed private and profitable for more than two decades, the company builds without short-term external pressure, so it suits people who want the space to take their time and get things right rather than chase quarterly targets.
