About Sonar

Sonar helps prevent code quality and code security issues from reaching production, amplifies developers' productivity in concert with AI assistants, and improves the developer experience with streamlined workflows. Sonar analyzes all code, regardless of who writes it — your internal team, genAI, or third parties — resulting in more secure, reliable, and maintainable applications. Rooted in the open source community, Sonar’s solutions support over 30 programming languages, frameworks, and infrastructure technologies. Today, Sonar is used by +7M developers and 400K organizations worldwide, including the DoD, Microsoft, NASA, MasterCard, Siemens, and T-Mobile.

We believe in developing great products that are supported by great internal teams and a strong culture. We are highly committed to and obsessed with the company, users, each other, and our open source community. We have high standards and hold each other accountable for acting with positivity, dedication, thoughtfulness, empathy, and passion daily. We are deliberate with our decisions with high clarity of intention. At the same time, we feel extreme urgency and move forward quickly. And lastly, we are highly effective and operationally efficient. We operate collectively as One Team to accomplish our goals.

At Sonar, CODE is more than just an acronym – it's a mindset that defines daily operations.

Why You Should Apply

At Sonar, we’re a group of brilliant, motivated, and driven professionals working hard to help supercharge developers to build better, faster. Sonar helps to continuously improve code quality and code security while reducing developer toil. This means that developers can focus on doing more of what they love and less of what they don’t. Our solutions don’t just solve symptoms of problems – we help fix issues at the source – for all code, whether it's developer-written, AI-generated, or from third parties.

We have a dynamic culture with employees worldwide and hub offices in the USA, Switzerland, the UK, Singapore, and Germany. Team members should be able to come to work every day, work on a product they are proud of, love what they do, and feel energized by their peers. With our roots deep in the open source community, we’re all about the mission: supercharge developers to build better, faster.

The Impact You Will Have

The Sonar Analysis Team is seeking a passionate versatile Software Engineer to contribute to our analyzers for the mobile domain.

The mobile analyzers are the analyzers for Kotlin, Swift, and Dart. They are designed to fulfill the needs of mobile developers on various technologies: spotting tricky code quality and security issues as fast as possible while generating as little noise as possible. You’ll be able to use your expertise to bring valuable rules for Code Quality and Security in the mobile applications domain: starting from style issues and up to complex security vulnerabilities.

Joining the Mobile Squad offers the ultimate challenge of analyzing modern languages having different ecosystems: Kotlin, Swift and Dart. Every day you’ll have an opportunity to learn something new and accept new challenges.

What You Will Do Daily

• Have strong ownership of the team’s work and lead the execution of its sprints to completion: do specifications, write code and tests, review code from peers, validate features, and follow up on user feedback after the release.
• As the domain is quite new for SonarSource, you’ll often participate in investigations, explorations, and designing “Proof-of-Concept”.
• Develop new and maintain existing features for the Kotlin, Swift, and Dart code analyzers.
• Dive deep into the Mobile domain languages and argue about the best guidelines to use them effectively.
• Evolve the way our analyzers understand code by creating better models and developing new rules on top of them.
• Interact with compiler front-ends for Kotlin, S
