About the role
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
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. Performance, conduct, grievance, and exit cases — from intake through resolution.
Lead workplace investigations with rigor and discretion, producing findings and recommendations that hold up to scrutiny.
Partner daily with the Head of Employment Law (Austin) on complex or high-risk cases, ensuring practice stays aligned with employment law across every jurisdiction you cover.
Build and maintain the region’s ER case management framework, investigation protocols, and workplace policies, keeping them current as regulation evolves (UK, EU, and APAC employment law; EU AI Act and GDPR implications for People decisions).
Train and coach managers on early intervention and proactive feedback, working to reduce ER case volume over time, not just close what lands on your desk.
Report on ER metrics, case volume, time-to-close, and risk exposure, to give leadership a clear, data-backed view of workplace health across the region.
Experience and qualifications
7+ years combining HR Business Partner work with employee relations case management or workplace investigations, ideally across multiple jurisdictions.
Direct experience partnering with in-house or external employment law counsel on complex, high-stakes cases.
Experience supporting EMEA and/or APAC populations, comfortable with the added complexity of multiple legal systems and cultural norms in one remit.
Experience in a high-growth technology company where pace is fast and ambiguity is normal.
Solid grounding in UK and EU employment law fundamentals, with working familiarity with APAC frameworks (or a fast learner’s ability to build it)
Proven experience leading formal workplace investigations, from intake and evidence-gathering to written findings.
Comfortable with HRIS platforms (BambooHR or equivalent) and building your own data-driven narratives without relying on an analyst.
Familiar with, or actively curious about, AI tools in the HR workflow (Glean, Claude, or similar), with the judgment to evaluate outputs critically and own the final call.
How you show up
Discreet and trusted: people bring you sensitive situations because you handle them with judgment, confidentiality, and consistency.
Direct communicator: you bring leaders clear choices and a recommendation, not an escalation without a point of view.
Courageous: you hold the line on fairness and doing the right thing, especially when a case is uncomfortable.
Structured under pressure: investigations and ER cases don’t wait for a good day, you stay organised and even-handed when things get tense.
In-office culture
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.
We value diversity, equity, and inclusion
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 committed to fostering a diverse and inclusive work environment where everyone feels valued and empowered to contribute their best. 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.
If you need any accommodation, please reach out to us at .
All offers of employment at Sonar are contingent upon the results of a comprehensive background check and reference verification conducted before the start date.
Applications that are submitted through agencies or third party recruiters will not be considered.
