About the role

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, 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 still at the beginning of our growth journey and are continuously introducing new processes, technologies, and tools. In this role, you will:
Be a pivotal engineering contributor to the design, implementation, and operation of security controls and automation across our identity platforms, endpoints, and core IT services.
Own key parts of our IdP and access automation stack (e.g., SSO, SCIM, group‑based access, JIT access), ensuring that users get the right access at the right time with strong controls and auditability.
Design and maintain security monitoring, alerting, and SIEM integrations that give us real‑time visibility into identity, endpoint, and SaaS risks.
Partner with IT Ops, Information Security, and Infrastructure Engineering to ensure security controls are deeply integrated into operations (incident management, change, and problem processes), not bolted on.
Use and champion AI tooling to make security operations more efficient — from alert triage and runbook execution to knowledge retrieval and reporting.
Help define and improve how we measure the reliability and effectiveness of our security controls (SLIs/SLOs, error budgets, and dashboards), making risk and performance visible and actionable to stakeholders.
