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 Sonars 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.

At Sonar CODE is more than just an acronym its a mindset that defines daily operations.

Why You Should Apply :

At Sonar were 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 dont. Our solutions dont just solve symptoms of problems we help fix issues at the source for all code whether its 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 were all about the mission : supercharge developers to build better faster.

The Impact You Will Have :

At Sonar our team owns the external development experiences including the SonarQube IDE Extensions (VS Code IntelliJ Visual Studio) and the Sonar Model Context Protocol (MCP) server. With over 1 million active users we operate at a scale few developer tools achieve. The tools we build here are on the critical path for the worlds most impactful engineering teams having a tangible high-stakes impact on the global software supply chain.

We are navigating a massive industry shift from manually written to AI-co-authored code. As a Senior / Staff member of the IDE Experience squad you will define the vision for this hybrid engineering future architecting an inner loop that anticipates the needs of both human engineers and AI Agents. You will build the critical infrastructure that empowers the engineers to move fast ensuring that all code is born clean and secure before a PR is ever opened.

What You Will Do Daily :

• Build the Real-Time Feedback Loop . You will design and implement intelligent guidance systems that proactively steer both developers and AI agents toward secure patterns. Your mission is to ensure that security flaws and architectural drift are eliminated before a PR is opened.
• Lead the Technical Evolution . Youll drive architectural decisions for the IDE Extensions and their backend. You will solve for hard constraints : managing memory and CPU footprint providing low-latency responses and ensuring we never block the UI thread to protect the engineers flow state.
• Architect the Context Engine for AI Agents . You will contribute to the development of the Sonar MCP Server and Sonar CLI allowing local AI Agents (like Cursor GitHub Copilot Claude Code etc.) to ask for project rules and security context before they generate code.
• Champion a Unified Experience . You will ensure our tools feel native in every IDE while sharing a robust logic core. You will bridge the gap between platform-specific implementations (TypeScript / C#) and our shared backend (Java) to prevent feature fragmentation across the ecosystem.
• Act as a Technical Force Multiplier. Beyond writing code youll mentor the squad through design reviews and collaborate with the Code Quality and Security teams to ensure our static analysis engine runs efficiently in a live local environment.
