Java Developer (m/w/d) - Java Software Engineer

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. 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:
Currently topping the leaderboards for agentic software repair.
Our team operates across global hubs in Austin, Bochum, Dubai, Geneva, London, Singapore, Tokyo, and Washington D.With over $400M in revenue and profitable, fast-paced growth, we are building the backbone of the AI software revolution. Spend the remainder of your time (roughly 30%) hands-on in our Java/Spring codebase: reviewing agent-generated pull requests, fixing what they get wrong, and feeding those lessons back into the tooling.
Contribute to the Architecture Decision Records (ADRs) and standards that govern how the Unified Core evolves.
Hands-on experience building or operating multi-agent or LLM-agent systems in a real production setting — not just prompting a coding assistant, but designing the orchestration, tool-use, and guardrails around autonomous agents.
Experience building evaluation or verification systems for AI-generated changes: automated testing, static analysis, regression detection, or comparable safety nets for code you didn't personally write.
Strong software engineering fundamentals in Java and Spring (or a comparable JVM/enterprise stack) — enough to read a large, mature codebase critically and tell good architecture from bad.
