QA Engineer (IJ Platform / Remote Development)

Responsibilities

• JetBrains Runtime (JBR) is our fork of OpenJDK, used to launch all IntelliJ-based IDEs. When runtime issues occur, they affect every developer relying on our products. This role exists to ensure JBR remains stable, performant, and reliable across platforms.
• You’ll take ownership of quality across JBR builds, working closely with the engineers building features like Java Chromium Embedded Framework (JCEF) and contributing to OpenJDK projects. You’ll influence how we triage, investigate, and resolve complex JVM issues, directly shaping the stability of the entire IntelliJ…
• Day to day, you will
• Analyze automated test results from regular builds to investigate Java runtime and test failures.
• Conduct thorough investigations into user-reported issues to ensure accurate triage.
• Analyze thread dumps and JVM crash logs to pinpoint deadlocks, freezes, and Event Dispatch Thread (EDT) responsiveness issues in the IDE.
• Communicate with developers to build a deep understanding of runtime architecture and ongoing changes.
• Collaborate with the support team to reproduce and resolve issues reported in public builds.
• Take ownership of JetBrains Runtime quality by identifying what needs to be fixed, keeping the tracker organized, and prioritizing quality tasks.
• Success in this role means runtime issues are caught early, triaged effectively, and clear context is provided to developers so fixes happen swiftly. You’ll have established a clear view of JBR quality, unblocked internal teams, and improved overall IDE stability for millions of users.
