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: SonarQube for IDE is an advanced plugin designed for leading Integrated Development Environments (IDEs) to help developers identify and remediate code quality and security issues. By performing real-time analysis and highlighting potential problems, this tool integrates seamlessly with SonarQube Server and SonarQube Cloud, providing a comprehensive development experience. We are seeking a senior software engineer to join our dynamic IDE Experience squad. In this role, you will contribute to building the next generation of developer tools by designing and delivering features that help ensure human and AI-generated code meets quality and security standards within the most popular IDEs. Your objective will be to make SonarQube for IDE an indispensable tool for all developers. What You Will Do Daily:

Join the IDE Experience squad, responsible for the development of the SonarQube for IDE extensions; you will contribute to all supported IDE extensions, and help expand support to new tools and ways of writing code. Your responsibilities will include leading specifications, writing code and tests, mentoring other squad members (through code review, pair programming and coaching), and participating in the roadmap definition and planning.

Become an expert on multiple extensibility SDKs, using Java, Kotlin, Typescript, C# (and more), for both widely adopted and up-and-coming IDEs, pushing the boundaries of what can be done with their APIs.

Keep up with the latest tools and techniques for AI-assisted coding and for assessing AI-generated code. Share findings and best practices with your squad, and actively contribute to a safety- and quality-first culture when integrating AI development assistance.

Engage with the Open-Source community, other SonarSourcers, and the Support team and integrate their feedback.

Foster continuous improvement within your squad by participating in retrospectives, sharing your technical expertise, and taking on a fair share of the team’s workload.

The Experience You Will Need:

8+ years of hands-on experience as a Software developer with strong expertise in Java.

Proven track record in software development with an “expert generalist” profile (curiosity, solid Computer Science fundamentals knowledge, collaborativeness, open-mindedness, a good blend of generalist and specialist skills).

Experience with, and a strong interest in, AI-assisted coding —paired with the ability to systematically and critically assess the accuracy, reliability, usability, and security of AI-generated code.

Fluency in agile methodologies, source code quality, and associated practices: including clean code principles, tests (unit and functional), CI/CD, and code reviews.

Fluency in English, both written and spoken.
