Agentic Software Engineer (f/m/d)

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. What you will do Spend the majority of your time (roughly 70%) designing, building, and iterating on agentic tooling: orchestration, tool-use, context management, and evaluation harnesses for autonomous code-modification agents. Build and refine the verification layer that gates what agents are allowed to ship — automated test generation, regression detection, static analysis (using our own SonarQube), and human-in-the-loop checkpoints where warranted. 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. Partner closely with the Server, Cloud Platform, and value-stream squads whose domains you're migrating — earning their trust and buy-in matters as much as the code itself. Contribute to the Architecture Decision Records (ADRs) and standards that govern how the Unified Core evolves. Track and evaluate emerging agent frameworks and techniques, bringing back what's genuinely useful — as distinct from what's just hype — for accelerating engineering across Sonar. Experience and qualifications 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. A track record of owning complex, ambiguous technical problems independently and driving them to resolution — this is an R&D-flavored role inside a production platform team, and you'll be shaping the playbook, not following one. Experience influencing engineers and squads you don't manage — the migrations you'll enable depend on their trust as much as on your code. Additional comments This role is based in Bochum, Germany .
