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
 
Our website is the front door to the Sonar ecosystem. It is where developers and organizations discover our products, and where our marketing and data systems connect to the outside world. You will work across both sides of that: building the UI people see and the integrations they do not.
You will start by contributing across the full stack and progressively own entire domains end-to-end:
  • UI delivery: Build accessible, performant components from design specs for a growing number of websites that serve a global audience across 7 languages.
  • Analytics & tracking: Own how we instrument the websites (event tracking, data layer, tag management) so that marketing and product teams can measure what matters.
  • Marketing integrations: Own the backend connections between our frontend and our business systems (forms, lead capture, automation workflows) ensuring data flows accurately from the browser to internal tools.
We have built our development workflow around AI-assisted coding and we expect you to push that further. AI handles more of the repetitive work over time, which means your role expands into higher-impact territory, not less.

What you will do

  • Build UI components from Figma designs, collaborating closely with designers to iterate until it’s right.

  • Write and maintain content model migrations as our CMS structure evolves.

  • Implement tracking requirements from the marketing team, including new events, data layer updates, and tag configuration.

  • Build and maintain the server-side logic that powers forms, API routes, and integrations with external marketing systems.

  • Partner with the SEO and content teams on structured data, metadata, and internationalization.

  • Write tests, read code reviews, provide honest feedback and ship code.

  • Leverage AI coding tools daily, as a core part of your engineering workflow.

Experience and qualifications

  • 4+ years of professional web development: Hands-on expertise in TypeScript, React, and Node.js is required.

  • Quality-minded: You write tested code and care about what ships to production. Experience with modern testing tools and CI workflows.

  • Comfortable on the backend: You have built API routes, handled form submissions server-side, or worked with external service integrations. You’re not afraid of a server loader.

  • Curious about web analytics: Experience with tag management (GTM) or analytics instrumentation.

  • AI-fluent: You actively use AI coding tools (Claude Code, Cursor, Copilot...) in your daily workflow and look for ways to go further.

  • Pragmatic and Autonomous: You prioritize impact over technical novelty. You do not wait for direction, you investigate, form an opinion, take action, and iterate as you learn.

  • Nice to have: 

  • Experience with a framework (Remix, Next.js, React Router framework mode), Tailwind CSS, a headless CMS, or Storybook.

  • Experience with analytics tools (other than Google): Mixpanel, Fullstory

  • Experience with CRMs: SalesForce, Marketing Cloud

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!

Why Work With Us

We are a product-first company, with a people-first culture. Every employee has the opportunity to grow and learn.
