Senior Software Engineer (Java) - Remediation Agent in Genève

ph3Who is Sonar? /h3pSonar 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. /ppIntegrating 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. /ppWe 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: /pulliSonarQube: The world’s leading AI code review and verification platform. /liliSonarQube Foundation Agent: Currently topping the leaderboards for agentic software repair. /liliSonarSweep Sonar Context Augmentation: Providing the enterprise-grade context and constraints agents need to be truly effective. /li /ulpOur 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: /pulliCommitted to our customers and community. /liliObsessed with quality. /liliDeliberate in our decisions. /liliEffective as one team. /li /ulpWith 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. /ph3Position description /h3pAt 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. /ppRecent 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." /ph3What you will do /h3ullibArchitect the "Unified Remediation Engine". /bYou 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. /lilibBuild Robust Agent Architecture. /b 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. /lilibSolve the "Sandboxing" Problem. /b 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. /lilibEngineer for Reliability Safety. /b 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. /lilibAct as a Technical "Force Multiplier". /b 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. /li /ulh3Experience and qualifications /h3ullibStrong Backend Cloud Expertise. /bYou have 8+ years of experience building scalable resilient systems. You are strong in AWS architecture and know how to design for high availability and low latency with cost in mind. /lilibPolyglot Ecosystem (Java Python). /b You are comfortable operating in a hybrid environment: Java for deep integration with the Core Sonar analysis engine and Python for the AI/Agent reasoning layer. You should be strong in one and capable in the other. We make use of various LLM tools, and are looking for people not afraid of different languages. /li libSystems Thinking. /bYou understand that "AI" in production is mostly "Systems Engineering." You know how to handle asynchronous event-driven architectures, manage queues, and design sandboxed execution environments to run untrusted code safely. /li libAI LLM Integration. /b You have practical experience building applications that orchestrate LLMs (OpenAI, Anthropic, or hosted open models). You understand the backend complexity of RAG, context window management, and prompt engineering at scale. /li libData-Driven Mindset. /b 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. /li /ulh3Additional comments /h3pThis role is based in Geneva. We are unable to consider candidates unwilling to be in Geneva, but we are willing to relocate the right candidate. /ph3We value diversity, equity, and inclusion /h3pAt Sonar, we believe that our diversity is our strength. We are a global company that values and respects different backgrounds, perspectives, and cultures. We are committed to fostering a diverse and inclusive work environment where everyone feels valued and empowered to contribute their best. We are proud to be an equal opportunity employer and welcome all qualified applicants, regardless of race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status. /ppIf you need any accommodation, please reach out to us at /ppAll offers of employment at Sonar are contingent upon the results of a comprehensive background check and reference verification conducted before the start date. /ppWe do not currently support visa candidates in the US. /p /p #J-18808-Ljbffr
