Who is Sonar?

Sonar is driving the future of agent-centric software development. As the leader in AI code review and verification, 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, Git Hub 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, Service Now, , 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:

* Sonar Qube:
The world's leading AI code review and verification platform.

* Sonar Qube Foundation Agent:
Currently topping the leaderboards for agentic software repair.

* Sonar Sweep & 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

As a Senior Full-Stack Engineer for internal applications, you will be the engineering owner of custom solutions and integrations that connect our core business platforms (e.g., Salesforce, Stripe, Net Suite, licensing systems, etc.). You will be responsible for the entire lifecycle of these solutions-from architecture and design to implementation, deployment, monitoring, and continuous improvement.

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.

What you will do

* Design, Build & Maintain Integrated Internal Applications

* Own the end-to-end lifecycle of internal software applications and integrations: architecture, coding, testing, deployment, and maintenance.

* Translate business requirements into robust, scalable technical designs, including data models, APIs, system architecture, and UI flows where relevant.

* Implement full-stack features: write clean, efficient, and maintainable code for both back-end and front-end components; design and manage persistence layers; integrate with third‑party APIs (e.g., Salesforce, Stripe) and internal services.

* Build security & compliance into the design, incorporating data protection and regulatory requirements (e.g., GDPR) from the start, and collaborating with IST, ITOps, and Legal to ensure adherence to standards.

* Act as a Technical Partner to Business Stakeholders

* Collaborate with business stakeholders (e.g., Finance, Sales, HR, Business Technology colleagues) to clarify requirements, challenge assumptions, and co‑design pragmatic, value‑driven solutions.

* Support and guide User Acceptance Testing (UAT): provide technical support during UAT, address defects quickly, and ensure the delivered solution truly solves the underlying business problem.

* Communicate clearly on feasibility, trade‑offs, and timelines, serving as the technical point of contact and managing scope to protect solution integrity and production stability.

* Own the Full Development & Operational Lifecycle

* Implement and operate CI/CD pipelines to achieve reliable, frequent releases with a low change‑failure rate.

* Write and maintain unit, integration, and end‑to‑end tests to ensure high software quality and reduce regressions.

* Provide ongoing…
