Job Description

Sonar solves the trillion-dollar challenge of bad code. Sonar equips organizations to achieve and sustain a Clean Code state by empowering developers to write consistent, intentional, adaptable, and responsible code. Clean Code produces software that is maintainable, reliable, and secure, allowing development teams to spend less time fixing issues and more time innovating. With Sonar, and by employing the company’s Clean as You Code methodology, organizations minimize risk, reduce technical debt, increase productivity, and derive more value from their software in a predictable and sustainable way.

Sonar’s open-source and commercial products – SonarLint, SonarCloud, and SonarQube – support over 30 programming languages, frameworks, and infrastructure technologies. Trusted by more than 500,000 organizations and used by more than 7 million developers globally to clean more than half a trillion lines of code, Sonar is integral to delivering better software.

The SonarSource Analysis Team is looking for passionate Java Developers to create the most advanced static analyzers in the world. Those analyzers are at the heart of our products and aim to help millions of developers write clean code. By joining our team, you will be part of an autonomous team. You will have a word to say about what you will be working on. Within our team, you will be supported by great colleagues who are always willing to exchange knowledge. Using your skills, you will contribute to the growth of the development and professional capabilities of the team, and focus on what matters.

  • Have an opportunity to contribute to the growth of the team by participating in the recruitment process


On a daily basis, you will

  • Develop new and maintain existing features for code analyzers for different programming languages (Java, Kotlin, JavaScript, TypeScript, Python, Swift, TSQL, PHP and many others).
  • Evolve the way our analyzers understand code by creating ever better models and developing new rules on top of them.
  • Contribute to the open source community by developing open source products under the SonarSource umbrella and contributing back to libraries used by our products.
  • Help collectively define the team's short and long term goals.


The skills you will demonstrate

Words from the team

The Languages Team's mission is to build state-of-the-art static analyzers used by millions of developers.
We want to help developers to write better and safer code by spotting issues of several kinds for all major programming languages:
Maintainability issues: code smells
Reliability issues: bugs
Security issues: vulnerabilities and security hotspots

Ultimately, we target all issues which can be found through static analysis, even if they require a very deep understanding of the code. The sky's the limit! We believe that, as a side effect, our analyzers should educate developers about coding best practices thanks to the rule descriptions and to the raised issues.

From a SonarSource perspective, the mission of the Language Team is to generate the data that will provide the most valuable feedback for users of SonarSource’s products.

Why you will love it here

• We value a safe work culture - founded in respect, kindness, and the right to fail.
• We hire great people - we value communication skills as much as technical prowess and we strive to create a work environment that allows for everyone to succeed and feel empowered to do their best work. Our 500+ SonarSourcers from 35 different nationalities can relate!
• Work-life balance - a healthy work-life balance is very important at Sonar.
• Flexible hours - we schedule our days in order to be effective at work, while also being able to enjoy life’s important moments.
