What You Will Do Daily:
- Join the IDE Experience squad, responsible for the development of the SonarQube for IDE extensions; your main focus will be on SonarQube for Visual Studio. Your responsibilities will include contributing to specifications, writing code and tests, reviewing peers’ code, validating features, and managing releases.
- Become an expert on the Visual Studio Extensibility SDK, pushing the boundaries of what can be done with its APIs.
- Regularly evaluate the latest approaches for assessing AI-generated code. Share findings and best practices with the team, 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:
- Proven track record in software development with a strong focus on C# and the .NET ecosystem.
- Excellent engineering skills and a good understanding of Computer Science fundamentals and agile methodologies.
- Fluency in source code quality and associated practices: clean code principles, tests (unit and functional), CI/CD, and code reviews.
- Experience with, or 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 English, both written and spoken.

What the Team is Saying
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!
