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
- 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 qualifications
- Strong Backend & Cloud Expertise. You 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.
- Polyglot Ecosystem (Java & Python). 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.
- Systems Thinking. You 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.
- AI & LLM Integration. 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.
- Data-Driven Mindset. 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.

Sonar Insights
What We Do
Sonar provides the essential verification layer for the AI-driven development era, ensuring all code—whether human-written or AI-generated—is code you can trust. Today, AI coding tools are generating explosive volumes of code. This has created an "engineering productivity paradox" : faster code writing doesn't automatically lead to faster, safer software delivery. The new bottleneck is verification. Sonar solves this. Integrating code quality and code security into a single platform (SonarQube), Sonar is the foundation for high performance software engineering, analyzing over 750 billion lines of code daily to ensure applications are secure, reliable, and maintainable. As an independent verification platform, Sonar enables organizations to securely develop at the speed of AI. We are driven by a deep belief in our people, a commitment to excellence, and an unwavering dedication to delivery. We operate as a united group where our collective success is the sum of each individual's contributions. Our company culture is driven by the values of CODE: Committed, Obsessed, Deliberate & Effective. This mindset reflects our culture of creativity, collaboration, and pride in the work we do. Rooted in the open source community, Sonar’s solutions support over 35 programming languages, frameworks, and infrastructure technologies. Today, Sonar is used by 7M+ developers worldwide, including ServiceNow, Booking.com, Deutsche Bank, AstraZeneca, and Ford Motor Company. Sonar is headquartered in Geneva, Switzerland with additional offices in Austin, Texas; Bochum, Germany; London, Singapore, and Tokyo. The company is rapidly growing with over 800 employees! Join us in our mission to solve the trillion-dollar challenge of bad code!
