Who is 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, Swift and Dart and have the opportunity to contribute back to them.
• Provide mentorship to engineers to help them grow in their technical responsibilities and remove blockers to their autonomy.
• Collaborate with Product Managers and peers to define new features and set priorities, ensuring that the solutions fit into the Sonar ecosystem.
• Coordinate with different stakeholders to define the team’s short and long-term goals.

The Experience You Will Need:

• 6+ years of experience as a software developer.
• Technical versatility and readiness to work on different technical stacks.
• Good knowledge of engineering processes.
• Excellent engineering skills and a good understanding of Computer Science fundamentals.
• You have experience supporting and mentoring other team members.
• Compiler frontend knowledge is not required; you will learn it while working at Sonar.
• Leadership: you’re able to take initiative and bring a subject to completion with little to no supervision.
• Ability to learn fast.
• Open-minded and very positive can-do attitude.
• Comfortable in dealing with change and complexity.
• Self-confident to challenge the status quo as well as to be challenged.

Why You Will Love It Here:

• Our culture and mission set us apart. We have a dynamic work culture that values respect and kindness and embraces the right to fail (and get right back up again!).
• Great people make a great company. We value people skills as much as technical skills and strive to keep things friendly while still being passionate leaders in our domains.
• We have a flexible work policy that includes 3 days in-office and 2 days work-from-home each week for those located near our office locations; some locations such as Dubai, India, Japan and Australia operate fully remotely.
• We have a growth mindset. We love learning and believe continuous education is critical to our success. In an ever-changing industry, new skills are necessary, and we're happy to help our team acquire them.
• As the leader in our field, our products and services are as strong as our internal team members.
• We embrace transparency with regular meetings, cascading messages and updates on the growth and success of our organization.

Benefits of Working With Sonar:

• Pension Scheme: 1st Pillar (Unterstützungskasse): Automatic, financed by Sonar, 3% of gross salary, an additional benefit in addition to your salary.
• Pension Scheme:2nd Pillar (bAV): Voluntary, 15% contribution by Sonar from social security savings.
• We encourage usage of our robust time-off allocations with 28 PTO days for our employees based out of the Geneva region, plus additional days based on seniority and circumstances.
• Sonar recognizes holidays on working calendar days. If the holiday date occurs on a Saturday, we will recognize the day on the preceding Friday. If the holiday date occurs on a Sunday, we will recognize the day on the following Monday.
• Public transport reimbursement of 60% for annual subscription.
• Generous discretionary Company Growth Bonus, paid annually.
• Global workforce with employees in 20+ countries representing 35+ unique nationalities.
• We have an annual kick-off somewhere in the world where we meet to build relationships and goals for the company.

We Value Diversity, Equity, and Inclusion:

At Sonar, we believe that our diversity is our strength. We are a global company that values and respects different backgrounds, perspectives, and cultures.

We are committed to fostering a diverse and inclusive work environment where everyone feels valued and empowered to contribute their best. We are proud to be an equal opportunity employer and welcome all qualified applicants, regardless of race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.
