Who is Sonar?

Sonar is driving the future of agent-centric software development. As the leader in AI code verification and governance, 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

We're looking for a Senior or Staff Technical Writer to join the Sonar documentation team. We want someone who thinks like a developer, writes like a communicator, and builds documentation the same way engineers build software.

You'll own developer-facing content across the SonarQube product suite: conceptual guides, integration tutorials, and release documentation. You'll work directly alongside engineers and PMs, live in the same repos and PRs they do, and be expected to catch a broken code sample the same way you'd catch a grammatical error. You'll also shape how we think about documentation as a discipline — owning tooling decisions, defining style and structure, and raising the bar for the whole team.

As a Software Technical Writer, you will own developer-facing content across the SonarQube product suite. Your work will directly shape how practitioners using Sonar products—including developers, DevOps, and platform engineers—approach code quality and security. You will be the trusted expert, translating complex capabilities into practical knowledge. By crafting compelling, hands-on educational content, such as conceptual guides, in-depth tutorials, how-to-guides, etc, to help enable millions of practitioners to write high quality, secure code. You won't just explain features; you will define the developer's journey with our products, establishing Sonar as an essential part of their Agentic SDLC workflow. You'll also shape how we think about documentation as a discipline. You will influence tooling decisions, help define style and structure, and raise the bar for the whole team.

What you will do

Plan, write, and maintain high-quality documentation for developer audiences: getting-started guides, how-tos, conceptual explanations, and release notes
Work in a docs-as-code workflow — authoring in Markdown, submitting PRs, reviewing diffs, and running docs through the same CI pipeline as code
Use AI tools to accelerate research, drafting, and content auditing — and take full ownership of the quality and accuracy of the output
Collaborate with engineers to document new features accurately and on time, often working from specs, early builds, and code review comments
Verify, and maintain code samples (in languages relevant to our integrations) to ensure they compile, run, and stay current with product changes
Audit and improve existing documentation for accuracy, completeness, structure, and voice
Help evolve the team's style guide, information architecture, and content standards
Mentor other writers and serve as a technical resource for docs-adjacent questions from engineering

Experience you will need:

Proven track record of creating technical content for developer audiences (provide portfolio/examples)
Fluency in a docs-as-code workflow: Markdown or similar markup, Git (branching, PRs, rebasing), and working inside a repo as a first-class collaborator
Strong software development or DevOps background with proficiency in some programming languages
Fluency in a docs-as-code workflow: Markdown or similar markup, Git (branching, PRs, rebasing), and working inside a repo as a first-class collaborator
Comfort using AI tools (Claude, Codex, Copilot, etc.) to augment your workflow, with a clear-eyed approach to validating AI-generated content
Experience working cross-functionally with engineering and product teams to ship documentation alongside features
Strong instinct for information architecture: you know the difference between a tutorial, a how-to, a reference, and a concept and when to use them

Nice to Have

Solid understanding of DevOps practices including CI/CD pipelines
Experience writing documentation for the agentic SDLC
Experience with code quality, security, and testing concepts including SAST, DAST, code coverage, and vulnerability management
Demonstrated ability to read, write, and debug code — whether through writing verified code samples in technical articles, a background as a developer or software engineer, or equivalent hands-on experience

In-office culture

We're intentional about this. We believe the best teams are built in the room together. Three anchor days — Mondays, Tuesdays, and Thursdays — create the collaboration rhythm that makes a hub office worth having.

Candidates need to be genuinely based in the location the role is posted — if that's not where you are today, we're happy to support relocation for the right person.

We value diversity, equity, and inclusion

At 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.
