Staff Software Engineer (Java) - Billing

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 are looking for a driven, autonomous and impactful Staff Engineer to join the Billing Squad within our StoreFront department.

The Billing squad is one of the most cross-functional and fastest growing development teams within Sonar. We enable the release of all the new products that Sonar is currently bringing to the market, both for large and small customers. The AI-native, usage-based nature of our product offering is pushing us to rethink how we develop and implement innovative pricing models. This is pushing us to our limits every day!

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 billing 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.

What you will do

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

Work cross functionally with product squads and go-to-market teams to ensure smooth release of new features and products.

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.

Experience and qualifications

Over 6 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.

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

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 with billing and payment processing systems (we use Stripe) and/or general experience with subscription management is highly desirable.

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.

If you need any accommodation, please reach out to us at 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.
