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
What you will do
- Build the "Glue": You won't just design on whiteboards; you will write the high-leverage code—whether it’s a custom Backstage plugin, a specific GitHub Action, or a CLI in Go/Python—that bridges the gap between our raw infrastructure and the developer experience.
- Experiment & Prototype: You will create "Tracer Bullet" implementations for new architectural standards, proving they work in code before advocating for their adoption across the fleet.
- Engage as an Embedded Expert: You will partner directly with Product Squads, not as an auditor, but as a co-pilot—helping them adopt the Golden Paths and gathering direct feedback to iterate on the platform product.
- Mentorship & Technical Leadership: You will elevate the technical bar of the Platform Engineering division, mentoring other engineers on modern software design, automation strategies, and "Platform as a Product" thinking.
Experience and qualifications
- Principal-Level "Builder" Mindset: You have 10+ years of software engineering experience and still love to code. You are comfortable jumping into a complex Java/Python codebase to refactor a core component or writing a new tool in Go/TypeScript from scratch.
- Cloud Native Architecture Mastery: You possess deep technical expertise in modern infrastructure standards— Networking, Containers and Kubernetes. You understand how to design distributed systems that fully exploit these platforms (e.g., resilience patterns, sidecars, ephemeral scaling) rather than just "lifting and shifting" legacy applications.
- Forward-Looking Innovation (AI & Agents): You have a pulse on the future of software engineering. You are actively exploring how GenAI, LLM Agents, and intelligent automation can revolutionize the developer experience, and you have the curiosity to build the experimental tools that prove it.
- Platform Product Engineering: You treat internal infrastructure as a product, but you understand that the best interface is no interface. You have moved beyond building static Service Catalogs (like Backstage) and have experience building CLI-first platforms and IDE-integrated workflows that scale "Golden Paths" to hundreds of users without forcing them to switch contexts.
- Influence without Authority & Internal Evangelism (DevRel): You combine the empathy of a Developer Advocate with the strategic weight of a Principal Engineer. You drive adoption not by mandate, but by winning hearts and minds—marketing the platform’s value, building internal communities, and acting as the "Sales Engineer" for the Golden Path

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!
