Summary and responsibilities
Role overview
Summary
This Full Stack Engineer role at Sonar involves developing and maintaining the company's global website, which serves as the primary interface for product discovery and marketing data systems. Responsibilities include building accessible UI components from design specifications, owning analytics and tracking instrumentation, and managing backend integrations with business systems to ensure accurate data flow.
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

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, SonarQube Foundation Agent, SonarSweep & Sonar Context Augmentation.
