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.

We are looking for a highly impactful Staff Engineer to join the Identity Squad within our StoreFront department.

The Identity squad is the cornerstone of trust and access across Sonar's product ecosystem. The squad is responsible for everything related to authentication (AuthN) and authorization (AuthZ) for all of Sonar’s products. We operate services at scale, handling 1000s of requests per second. As a Staff Engineer, you will be architecting robust, scalable, and highly secure identity solutions that seamlessly bridge our cloud and self-managed offerings. As a Staff engineer you will also play a crucial role in mentoring other engineers, helping them grow their skills and expand their impact.

You will partner closely with Product Managers, Engineering Managers, and other Staff/Principal Engineers across the organization to lead the end-to-end delivery of critical identity features. You will take ownership—from initial architecture and design through to implementation and deployment—of major initiatives ensuring a frictionless yet highly secure experience for millions of developers.

Collaborate with UX designers, Product Management, and engineering teams to deliver robust security features alongside an optimal user experience.

Take strong ownership of squad deliverables and effectively drive sprints toward successful completion.

Architect and guide the design of our on-premises and AWS cloud applications.

Oversee feature deployment, production monitoring, and troubleshoot team-specific live issues.

Mentor engineering team members to help them grow in their technical responsibilities and remove blockers to their autonomy.

Contribute to the definition of the team’s short and long-term goals.

Over 8 years of software engineering experience, including working as a Tech Lead, Staff Engineer, or Software Architect.

Proven ability to take initiative and bring a subject involving several stakeholders and engineers to completion with little to no supervision.

Experience supporting and mentoring other team members.

Proficiency with Java coupled with a strong passion for Clean Code and rigorous software quality standards.

Experience architecting cloud-native applications.

Experience with relational RDBMS (such as Postgres) and SQL.

Domain expertise in Identity and Access Management (IAM), including hands-on experience with AuthN/AuthZ protocols (OAuth2, OIDC, SAML, JWT) and user provisioning (SCIM).

Proficiency in working with and steering AI coding tools (Codex, Claude, etc).

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.

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.

If you need any accommodation, please reach out to us at hiring@sonarsource.com.

All offers of employment at Sonar are contingent upon the results of a comprehensive background check and reference verification conducted before the start date.

Applications that are submitted through agencies or third party recruiters will not be considered.
