Full Stack Engineer

You will integrate Sonar’s business-critical systems (e.g. Salesforce, Stripe, NetSuite) and build standalone solutions for specific needs. This will typically involve applying AWS event-driven architecture to solve internal user needs via a scalable and reliable end-to-end business platform.

You will be responsible for the entire lifecycle of these solutions (architecture, to implementation, to ongoing monitoring and maintenance/improvements), working directly and in close partnership with business functions (e.g. Sales, Finance, Product).

About Sonar

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.

Responsibilities

• Your work (reliable, scalable, performant and secure applications) and skills (ability to translate complex business needs, coupled with a strong sense of ownership, urgency and partnership) will make you a trusted partner who drives significant efficiency and process improvements for the company.
• Design, build and maintain serverless, event-driven integrations on AWS (Lambda, EventBridge, SQS, DynamoDB, Secrets Manager).
• Evaluate in-house and third-party API options, based on Sonar’s specific operating context.
• Build in-house web applications when third-party applications are unsuitable or unavailable.
• Ensure non-functional requirements (e.g. security, scalability, reliability) are addressed, on an ongoing basis (e.g. monitoring UI, health-checks, alerts and notifications).
• Work with stakeholders to understand requirements (stated as well as implied), document design decisions for peer-review/challenge.
• Follow governance principles (e.g. least-privilege IAM, secret management), processes (e.g. change management approvals) and tools (e.g. CI/CD to ship changes safely).

Requirements

• 5+ years of professional full-stack development experience.
• Proficiency in working with and steering AI coding tools (Codex, Claude, etc).
• Hands-on AWS experience with serverless services and event-driven design.
• Strong skills in a modern language (TypeScript preferred).
• Clear written/verbal communication and experience with business/technical stakeholders.
• Experience running production on-call for business-critical integrations.
• Proactive, driven and attention to detail - willingness to take ownership.
• 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.

Preferred

• Stripe/Salesforce integration will be a significant plus; Databricks experience nice to have.

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.
