Software Engineer (Qodana Core)

Do you love dissecting code to understand how it really works, and want to build tools that help millions of other developers trust theirs?

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.

We build Qodana to bring the intelligence of JetBrains IDEs directly into the CI/CD pipeline, helping engineering teams spot security flaws, license issues, and bugs before they ever reach production. As AI-assisted coding grows, the need for deep, static code analysis is more critical than ever.

In this role, you’ll join our Qodana Core team to expand our static analysis engine and design new algorithms for complex, inter-procedural code analysis. You will have direct ownership over how we configure and orchestrate these analyses across different environments. You’ll collaborate closely with other JetBrains compiler and IDE teams, directly influencing how development teams worldwide maintain code quality and adopt AI safely.

• Design and implement new static analysis checks, rules, and inter-procedural analysis algorithms.
• Extend Qodana’s capabilities in critical areas like license compliance, security, and vulnerability detection.
• Optimize how code analysis runs, configure execution paths, and orchestrate performance based on project context.
• Build and refine CI/CD integrations to make Qodana easy to adopt across different development workflows.
• Collaborate with compiler and IDE teams across JetBrains to share insights and align analysis engines.
• Take ownership of features from early concept to release, gathering feedback and iterating to make them better.

• A deep curiosity about code structure, compilers, and how static analysis works.
• A proactive mindset, not waiting for permission to fix a broken process or improve a system.
• Strong collaboration skills and a readiness to support your technical ideas with clear, logical reasoning.
• Comfort working in a distributed team across different countries and time zones.
• A focus on quality over quick fixes, valuing long-term maintainability in your work.
• Experience with developer tooling, static analysis, application security, or LLM-based applications would be a plus. Familiarity with languages and ecosystems beyond the JVM – such as C++, Rust, JavaScript or TypeScript, Python, .NET, or Go – would also be valuable.

• Deep, practical knowledge of JVM development (such as Kotlin or Java).
• Experience designing and implementing complex algorithms or handling performance-critical backend architectures.
• Fluent communication skills in English to collaborate with team members globally.

• First 3 months: You will get familiar with the Qodana codebase and the IntelliJ Platform architecture, delivering your first set of analysis rules and integrations.
• First 6 months: You will take full ownership of specific analysis features, collaborating with neighboring teams to design robust solutions for complex codebases.
• Long term: You will help shape the technical direction of Qodana Core, continuously raising the bar for static analysis performance and developer experience.
