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 Goldman Sachs AstraZeneca and Ford Motor on us to provide independent explainable consistent review and governance of their AI-generated code via products like:

  • SonarQube: The worlds 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 youre 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.

You will raise the engineering bar through high standards for code quality automated testing and delivery practices. You will operate as an AI-native engineer who uses AI tools programmatically - accelerating routine tasks while maintaining full ownership of design correctness and security.

What you will do

  • Design and implement features across the stack: backend services and APIs frontend components and flows and the integration between them.
  • Collaborate with Product Managers UX designers and other engineers to clarify problems propose solutions and break the work into incremental shippable slices. As the work is done you will also help raise awareness of problems across the team.
  • Own the delivery lifecycle of your work: automated tests CI pipelines deployment and followup on metrics and production behavior.
  • Use AI assistants pragmatically to speed up lowlevel tasks (boilerplate refactorings test scaffolding) while keeping full responsibility for architecture and quality.
  • Review code and participate in design discussions providing clear and constructive feedback - including on AIgenerated code.
  • Improve the systems and pipelines that allow AI-generated code to be safely integrated into production.
  • Identify and tackle pragmatic refactoring opportunities and technical debt to improve maintainability performance or developer experience.
  • Mentor teammates in both technical excellence and effective AI-native workflows.
  • Share responsibility for service availability with your team collaborate with customer facing teams to investigate issues and participate in on call rotations.

Experience and qualifications

  • 5 years of experience building and operating webbased products in production cloud environments.
  • Strong backend skills in Java (our core backend language) or an alternative backend focused language such as Go or Python.
  • Experience designing implementing and consuming HTTP APIs.
  • Solid frontend experience with a modern JS/TS stack (e.g. React or similar) including component design state management and testing.
  • Familiarity with databases and web infrastructure (relational storage caching messaging queues REST/JSON AuthN/Z).
  • Experience architecting cloud-native applications.
  • Hands-on experience with automated testing CI/CD and observability practices.
  • Experience evaluating and integrating AIassisted development tools into your workflow while maintaining high quality and security standards.
  • Extensive hands-on experience with experimentation incorporating customer feedback into the development cycle.
  • Practical experience with distributed systems that serve millions of users.
How you work:
  • Ownership and accountability: You feel responsible for the longterm health and correctness of what you ship whether written by you or generated with AI assistance.
  • Collaborative by default: You communicate with clarity seek alignment early and view candid feedback as a tool for growth.
  • AInative mindset: You treat AI tools as collaboratorsnot oraclesvalidating their output understanding their limits and using them to focus on highervalue design and problemsolving.
  • Pragmatic and incremental: You balance architectural excellence with the need to deliver value quickly and iteratively.
