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 impact you can have
As an AppSec Researcher, you play a central role in realizing our ambition to provide the best SAST solution on the market. Like us, you believe that application security is not the responsibility of a few experts and that developers can have the biggest impact when they get the right information at the right time. As a member of the AppSec team, you decide what security issues the product should detect and how they materialize in various language ecosystems. You work closely with static analysis developers to specify, clarify, communicate, and validate all functional aspects of the security rules. You will be a trusted adviser of developers, able to provide meaningful code samples and specifications. This is a great way to have a direct impact on the product and so on the way millions of developers produce code.
On a daily basis, you will
- Build expertise on various language ecosystems in order to identify the most common vulnerabilities that developers are facing.
- Investigate how these vulnerabilities materialize within the code.
- Define the security rules that will detect these vulnerabilities.
- Interact with our user community to clarify and turn this invaluable feedback into actions/decisions: like too noisy vulnerability detection rules or taint-analyzer reporting vulnerabilities without enough contextual information.
- Drive innovation to make our SAST engine even better.
- Study competitors and provide gap analyses.
The skills you will demonstrate
- Technical skills
- Mastering AppSec basics, including knowing the most common vulnerabilities, how to locate vulnerabilities in the code, and how to exploit basic vulnerabilities. To be successful, you should be interested or involved in the application security ecosystem.
- Having a developer mindset: experience with coding lifecycle, ability to produce secure code, to do code reviews, and to jump into an unknown codebase, language, and framework.
- Master at least one programming language along with its development environment to understand end-users' context and expectations.
- Strong communication skills, i.e. both listening and expressing constructive ideas.
- High level of autonomy and still accepting help and feedback from team members.
- Ability to work and communicate with non-security experts.
- Understanding of static analysis mechanisms.
- Ability to challenge rule implementation.
- Capability to bring a new field of expertise and convert it to additional value to the product.

Nice to have
Words from the team
We are a team of 8 AppSec Researchers with the mission to imagine, define, and maintain security rules used by developers worldwide. We study how developers introduce weaknesses in their applications. We ensure that our security rules are tailor-made for the most widely used environments. We also examine the issues that our products encounter on open-source projects where we chase false positives. We are a team of passionate people who enjoy learning from each other. Every day, we work to provide developers with the best rules and help them own the security of their code.

What We Do
Software-driven digital innovation is essential for competing in today's market, and the foundation of this innovation is code. However, there are widespread cracks in this foundation – lines of bad, insecure, and poorly written code – that manifests into tech debt, security incidents, and availability issues. With Sonar, developers and organizations are empowered to create quality, secure code confidently, whether written by humans or generated with AI.
The Sonar solution, SonarQube, helps prevent code quality and 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 or genAI—resulting in more secure, reliable, and maintainable software.
At Sonar, 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 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.
