About this 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

SonarSource is looking for a passionate AI Engineer who will be a driving force in our internal operations. You will play a central role in Sonar's AI transformation, applying your expertise to solve internal business operation problems, automate complex processes, and amplify productivity across departments using cutting-edge AI agents and full-stack tools. Your work will directly enhance our operational efficiency and strategic agility.

What you will do

  • Design & Develop: Architect and implement end-to-end AI Agents and full-stack applications that automate complex business processes.
  • Foundational Engineering: Build and maintain the core AI tech stack, including agent orchestration frameworks, vector database integrations, and RAG (Retrieval-Augmented Generation) pipelines.
  • Cloud Orchestration: Oversee the deployment and management of scalable AI services, selecting and adapting infrastructure to meet stringent requirements for high availability, performance, and efficiency.
  • Strategic Transformation: Act as a key contributor to Sonar’s AI transformation, identifying high-impact opportunities for agentic automation across different departments.
  • Governance & Ethics: Collaborate with cross-functional teams to establish governance, security protocols, and best practices for AI development and data privacy.
  • Full-Stack Ownership: Manage the entire lifecycle of internal tools, from backend logic and LLM prompt engineering to intuitive frontend interfaces for internal users.
  • Mentorship: Guide junior engineers and contribute to a culture of technical excellence in AI and automation.

    • Experience and qualifications

  • Full-Stack Expertise: 5+ years of professional experience in full-stack development (e.g., Python, Node.js, React, or similar modern stacks).
  • AI Agent Mastery: Proven experience developing and deploying autonomous AI Agents using frameworks such as LangChain, AutoGen, CrewAI, or similar.
  • Automation Roots: A strong background in traditional automation development (e.g., scripting, workflow engines, or RPA) prior to the LLM era, demonstrating a deep understanding of logic-based systems.
  • Cloud Proficiency: Hands-on experience architecting and deploying production-grade applications on any major cloud platform (AWS experience is highly recommended).
  • Architectural Vision: Deep understanding of the specific architectures required for agentic workflows, including state management, tool-calling, and memory systems.
  • Data & AI Skills: Experience with vector databases (e.g., Pinecone, Weaviate), fine-tuning (optional but preferred), and advanced prompt engineering.
  • Collaborative Mindset: Ability to work with non-technical stakeholders to define governance and translate business needs into technical requirements.
  • Growth Mindset: A passion for staying at the forefront of AI research and a desire to continuously evolve your skill set.
