Who is Sonar?

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.

What You Will Do Daily:

• Conduct inbound and outbound prospecting activities, including cold calls, email outreach, and LinkedIn engagement.

• Research and identify potential leads and target accounts based on defined criteria.

• Leverage various tools and resources like Salesforce, Salesloft, and Zoominfo to build and maintain a healthy pipeline of prospects.

• Qualify leads by assessing their fit with our ideal customer profile and understanding their needs.

• Document and update lead information and interactions in our CRM.

• Collaborate with marketing to align lead-generation efforts with campaigns and initiatives.

• Collaborate with the sales team to transition qualified leads for further engagement.

The Experience You Will Need:

• Proven successful experience in outbound lead generation; ideally in a SaaS or subscription model.

• Strong time management and attention to detail.

• Highly organized and strategic in workflow.

• Strong English-language communication and listening skills: ability to handle objections as well as to take feedback and coaching.

• A proactive attitude and goal-oriented mindset with a focus on meeting or exceeding targets.

• Strong collaboration and teamwork skills to work closely with the sales teams.

• language skills: Korean
