About the role
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. Recent breakthroughs in AI have made autonomous remediation a reality, but one major hurdle remains: Trust . Generative AI makes mistakes, and enterprises cannot automate what they do not trust. This is where you come in. As a Senior/Staff Engineer, you will architect the backend for Verified Autonomous Remediation , a sophisticated Agentic workflow that doesn’t just generate code, but rigorously tests and validates it using Sonar’s analysis engine. You will tackle the hard engineering problems required to close the "Trust Gap." \n What you will do Architect the "Unified Remediation Engine". You will design the high-throughput decision logic that powers our remediation efforts. You will build the backend services that intelligently route requests between deterministic instant QuickFixes, LLM-based reasoning fixes, and complex Agentic flows. Build Robust Agent Architecture. You will contribute to the Sonar Remediation Agent code, transitioning research concepts to a resilient, high-scale production service. You will implement self-healing workflows where the Agent iteratively fixes the code it produces until the build is green. Solve the "Sandboxing" Problem. You will architect the secure execution environments required to run untrusted, AI-generated code. You will design the isolation layers that allow Agents to iterate on code improvements without compromising our infrastructure. Engineer for Reliability & Safety. You will implement critical safety mechanisms, like Circuit Breakers to automatically reroute requests to the proper engine when acceptance rates drop. Crucially, you will own the cost/performance trade-off, ensuring our AWS architecture scales to millions of events without letting token costs spiral. Act as a Technical "Force Multiplier". Beyond building systems, you’ll mentor the squad through design reviews and collaborate with the Research team to ensure our agent is not just state-of-the-art, but production-safe. Experience and
