JobsCloseBy Editorial Insights

SonarSource is hiring a Full Stack Engineer with a frontend focus to build the SonarQube Remediation Agent in Geneva. Expect about 70 percent of your time in React and TypeScript shaping the agent’s experience and telemetry, with the rest on the Agent Core in Java and Python to keep suggestions reliable. You should have 4+ years building web apps with React and TypeScript, comfort with Java and Python, and strong Git workflow experience, plus a clear focus on developer experience. Nice to have CI/CD, cloud, or AI workflow tooling. To apply, show concrete frontend impact, telemetry work, and collaboration with PM and UX, and note willingness to relocate to Geneva and visa constraints for the US.

Who is Sonar?
 

Sonar is driving the future of agent-centric software development. As the leader in AI code review and verification, we solve a critical problem: ensuring that software generated by AI-assisted developers or autonomous agents is reliable, secure, and maintainable.


Integrating seamlessly with Claude Code, Codex, Cursor, GitHub Copilot, Gemini, and Devin, we help over 75% of the Fortune 100 build trusted, reliable, compliant software. Customers who use Sonar are 44% less likely to report an outage due to AI-generated code.


We believe code verification is the critical missing link in the Agent-Centric Development Cycle (AC/DC). Industry giants like Nvidia, ServiceNow, Booking.com, Goldman Sachs, AstraZeneca, and Ford Motor Company.count on us to provide independent, explainable, consistent review and governance of their AI-generated code via products like:

  • SonarQube: The world’s leading AI code review and verification platform.

  • SonarQube Foundation Agent: Currently topping the leaderboards for agentic software repair.

  • SonarSweep & Sonar Context Augmentation: Providing the enterprise-grade context and constraints agents need to be truly effective.

Our team operates across global hubs in Austin, Bochum, Dubai, Geneva, London, Singapore, Tokyo, and Washington D.C. We move with a mindset we call CODE:

  • Committed to our customers and community.

  • Obsessed with quality.

  • Deliberate in our decisions.

  • Effective as one team.

With over $400M in revenue and profitable, fast-paced growth, we are building the backbone of the AI software revolution. If you’re hungry to have an impact, want to build at a fast pace, and ready to work at the forefront of AI, we want to hear from you.

 
Position description
 
At Sonar, we believe that simply reporting code issues is not sufficient. To truly level up the quality of the world's software, we must empower millions of developers to fix them automatically. With over 400,000 enterprises relying on our products, we hold a unique lever to shape how software is built.
 
We are building the SonarQube Remediation Agent, an agent that generates fixes and validates the changes against Sonar's analysis engine. We want to ensure that our agent is trusted by all engineers that use Sonar, and that trust is earned through every interaction that engineers have with the agent.
 
We need a Full Stack engineer with a strong frontend focus to make the agent's work transparent, interactive, and easy to review.

What you will do

Most of your time (around 70%) will be spent in React and TypeScript. You will architect the interaction layer for an autonomous agent. You will build the feedback loops that turn developer actions into telemetry, and design interfaces that help users safely orchestrate agentic executions. 

The remaining 30% is spent on the Agent Core. You will work with the backend to ensure our agent's suggestions are valid, performant, and aligned with our architectural blueprints. You will modify existing Java and Python services to  improve agentic logic and performance, validate pipelines, drive architectural alignment, and ensure reliability and scalability of the features you work on.

You will work directly alongside a dedicated product manager and UX designer.

Experience and qualifications

  • 4+ years of experience building web applications with React and TypeScript while writing clean, reliable code.

  • Comfortable navigating Java and Python codebases to support new frontend features.

  • Practical understanding of Git workflows, PR experiences, and platform integrations like GitHub or GitLab.

  • A clear focus on developer experience. You know how developers review code and what makes a tool feel helpful rather than intrusive.

  • You have a data-driven mindset. You care about the "Why." You want to build telemetry pipelines that distinguish between "Bad UX" and "Bad Code," focusing on the metrics that matter.

  • Experience or interest in 'Human-in-the-loop' systems and agentic workflows.

  • Strong opinion on the 'Verification Debt'. You understand that AI generation is easy, but verifying that it's correct (via tests, AST analysis, or gated PRs) is the real engineering challenge.

Nice to have

  • Previous work on developer tooling, CI/CD platforms, or user interfaces for AI workflows.

  • Experience with a Cloud Platform like AWS or GCP.
