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:

By joining Sonar, you will play a crucial role in enhancing SonarQube Cloud and SonarQube Server. You will provide teams and developers around the world with an exceptional experience, empowering them to develop better software.

As part of the role, you will join an on-call rotation, ensuring that critical system issues are promptly addressed, thereby minimizing downtime and maintaining a seamless experience for our users.

What You Will Do Daily:

  • Collaborate with Product Managers and UX designers to specify and design new features.
  • Participate in sprints with your team to deliver new features with a focus on the end user.
  • Maintain and enhance existing features, incorporating feedback from colleagues and the community.
  • Write comprehensive unit and integration tests to ensure code quality.
  • Conduct thorough code reviews and provide meaningful feedback to peers.
  • Contribute to the team's growth by improving organization, tools, and processes.

  • Modern Front-End Frameworks: Proficiency with React (preferred) or other modern front-end frameworks, ensuring efficient and scalable user interfaces (at least 5 years of experience).
  • Source Code Quality: Commitment to high-quality code through comprehensive unit and integration tests and end-to-end tests, ensuring robust and maintainable software.
  • Excellent communication skills: ability to articulate ideas clearly and engage with diverse stakeholders.
  • A team player: always willing to help and support others, enhancing their autonomy.
  • Independent, proactive, and eager to learn.
  • Taking initiative and leading a topic from beginning to end.
  • Not afraid to step outside their comfort zone and contribute to other technical areas

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.

What We Do

Sonar provides the essential verification layer for the AI-driven development era, ensuring all code—whether human-written or AI-generated—is code you can trust.

Today, AI coding tools are generating explosive volumes of code. This has created an "engineering productivity paradox" : faster code writing doesn't automatically lead to faster, safer software delivery. The new bottleneck is verification.

Sonar solves this. Our industry-leading platform, SonarQube, integrates code quality and code security analysis directly into the development workflow by automating reviews and providing actionable code intelligence for all code—first-party, AI-generated, third-party open source. \

For organizations, Sonar provides the critical SDLC governance and compliance reporting needed to de-risk AI adoption and manage standards at scale. We empower teams to "vibe, then verify" — innovating at the speed of AI without sacrificing the quality, security, or maintainability of their codebase.

We are driven by a deep belief in our people, a commitment to excellence, and an unwavering dedication to delivery. We operate as a united group where our collective success is the sum of each individual's contributions. Our company culture is driven by the values of CODE: Committed, Obsessed, Deliberate & Effective. This mindset reflects our culture of creativity, collaboration, and pride in the work we do.

Rooted in the open source community, Sonar’s solutions support over 35 programming languages, frameworks, and infrastructure technologies. Today, Sonar is used by 7M+ developers and 400K organizations worldwide, including Barclays, MasterCard, and T-Mobile.

Sonar is headquartered in Geneva, Switzerland with additional offices in Austin, Texas; Annecy, France; Bochum, Germany; London, England; and Singapore. The company is rapidly growing with over 750 employees!

Join us in our mission to solve the trillion-dollar challenge of bad code!

Why Work With Us

We are a product-first company, with a people-first culture. Every employee has the opportunity to grow and learn. We promote from within, provide regular feedback and professional development opportunities, value the right to fail along with respect and kindness and work with team members to achieve their full potential.
