Who is Sonar?
Sonar enables organizations to ship agentic code with confidence. Code creation is abundant, but confidence is scarce. Our core platform, SonarQube, verifies over 750 billion lines of code every day, delivering agentic verification and governance for all code. Trusted by more than 7 million developers and 75% of the Fortune 100, including teams at Nvidia, ServiceNow, Booking.com, Goldman Sachs, AstraZeneca, and Ford Motor Company, Sonar enables organizations to reduce outages, improve security, and lower the cost and risk of agentic software development.
Founded in Geneva and now headquartered in Austin, Texas, Sonar has a global team working across offices and hubs, including Silicon Valley, London, Bochum, Barcelona, Singapore, Tokyo, and the Washington, D.C. area. At Sonar, we’re enabling enterprises to build agentic software factories that can move quickly while maintaining the control, consistency and evidence required to ship with confidence.
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.
