Senior HR Business Partner, Employee Relations Specialist - EMEA & APAC

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, San Mateo (California), 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 Sonar’s EMEA and APAC footprint spans multiple legal jurisdictions, employment frameworks, and cultural contexts, from London to Geneva to Singapore. This role exists to give that population two things at once: a trusted HRBP who understands the business and the region, and a specialist who owns employee relations with the rigor and consistency a scaling, multi-jurisdiction company needs. You will carry a dual mandate. As HRBP, you will be the day-to-day partner for leaders across EMEA and APAC, helping them make sound performance decisions and be a trusted partner to the business and its leaders. As the region’s Employee Relations specialist, you will own case management, investigations, and workplace practice end-to-end, working daily alongside our Head of Employment Law (based in Austin) to make sure every case is handled compliantly, consistently, and compassionately. Your impact will show up in two ways: HRBP outcomes (org health, manager capability, retention) for the leaders you support, and ER outcomes (case volume, time-to-resolution, consistency of practice, and legal risk reduction) across the region. What you will do • Act as strategic HRBP for leaders across EMEA (Germany, UK, France, Switzerland) and APAC (Singapore, Japan), advising on org design, workforce planning, performance, and team dynamics with data and a point of view, not just a summary. • Use the HRBP people dashboard and org health data to prepare insights for leadership and manager 1:1s, flagging risks and decisions before they become urgent. • Support integration and engagement of new EMEA/APAC hires, partnering with Recruiting and People Ops on time-to-productivity and onboarding quality. • Translate global People strategy (career frameworks, calibration, internal mobility, compensation philosophy) into guidance that works across EMEA and APAC’s different regulatory and cultural contexts. Employee Relations & Workplace Practices • Own employee relations cases end-to-end across EMEA and APAC. Perfo
