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: As an Application Security 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 most significant impact when they get the correct information at the right time. As a member of the Code Security 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 to developers, able to provide meaningful code samples and specifications. This is a great way to directly impact the product and the way millions of developers produce code. What You Will Do Daily: 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 Experience You Will Need: Mastering application security 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. 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.
