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 Code Quality Team is seeking a passionate C++ Developer to contribute to our advanced CFamily analyzer.
SonarSource’s CFamily code analyzer is designed to fulfill the needs of C and C++ developers: spotting tricky code quality and security issues as fast as possible while generating as little noise as possible. Dereferences of null pointers, memory leaks, dead code, and logic flow errors … are some examples of those quality issues. The analyzer also helps enforce coding standards like CPP Core Guidelines and MISRA C++2023. The analyzer is built on top of the Clang front-end and can run inside the IDE as well as on CI systems. The analyzer is compatible with the mainstream C and C++ compilers: Clang, GCC, MSVC, and Arm.
Joining the CFamily team offers the ultimate challenge of analyzing C++, one of the most intricate programming languages in the world.
What You Will Do Daily:
- Develop new and maintain existing features for the C and C++ code analyzer.
- Dive deep into the C++ language and argue about the best guidelines to use it effectively.
- Evolve the way our analyzers understand code by creating better models and developing new rules on top of them.
- Interact with clang front-end and have the opportunity to contribute back to it.
- Collaborate with Product Managers and peers to define new features and set priorities, ensuring that the solutions fit into the Sonar ecosystem.
The Experience You Will Need:
- Solid understanding of the internals of the C++ language and familiarity with its latest standards.
- Fluency in C++ best practices for maintainable, secure, performant, and testable code.
- Curious and eager to learn about the small details of the C++ language.
- Compiler frontend knowledge is not required; you will learn it while working at SonarSource.
- Good knowledge of engineering processes.
- Excellent engineering skills and a good understanding of Computer Science fundamentals.
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.
