Sonar is driving the future of agent-centric software development. As the leader in AI code verification and governance, 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.


Sonar is seeking a college student interested in gaining hands-on experience in direct and indirect tax matters from both a domestic and international perspective.

This is a part-time hourly internship based in our Geneva office, offering up to 20 hours per week during the academic year and up to 40 hours per week over the summer. It is a great opportunity to dive into tax operations, gain real-world experience, and learn within a rapidly expanding company.
  • Conduct tax studies and research to help respond to various stakeholders tax questions.

  • Participate in the preparation of tax computation, tax reconciliations and tax provision.

  • Assist with transfer pricing computations and reporting.

  • Support the team on various tax projects.

  • Fluent in French and English. 
  • Master’s degree (or in progress) in tax law, accounting or finance.

  • Strong interest in international taxation.
  • Proficiency in standard software tools such as Excel, and demonstrated curiosity in using AI tools in finance or workflow optimization

  • Open-minded, ambitious, enthusiastic, with a team oriented spirit and eager to learn.

  • 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. 

    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.

     

    At Sonar, we believe that our diversity is our strength. We are a global company that values and respects different backgrounds, perspectives, and cultures.

We are proud to be an equal opportunity employer and welcome all qualified applicants, regardless of race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.
