Senior HR Business Partner (Employee Relations Specialist, EMEA & APAC)

Join Sonar, a fast-growing technology company, as a Senior HR Business Partner (Employee Relations Specialist) for the EMEA and APAC regions. In this dual role, you will serve as a trusted HRBP for leaders across EMEA and APAC, providing guidance on organizational design, workforce planning, performance, and team dynamics. You will also own employee relations case management, investigations, and workplace practices, ensuring compliance and consistency across multiple legal jurisdictions. Your impact will be measured through HRBP outcomes and employee relations outcomes.

• Act as a strategic HRBP for leaders across EMEA and APAC, advising on organizational design, workforce planning, performance, and team dynamics.
• Own employee relations cases end-to-end across EMEA and APAC, including performance, conduct, grievance, and exit cases, from intake through resolution.
• Build and maintain the region’s employee relations case management framework, investigation protocols, and workplace policies, keeping them current as regulation evolves.
• Experience in a high-growth technology company where pace is fast and ambiguity is normal
• 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
• Comfortable with HRIS platforms (BambooHR or equivalent) and building your own data-driven narratives without relying on an analyst
• Proven experience leading formal workplace investigations, from intake and evidence-gathering to written findings
• Solid grounding in UK and EU employment law fundamentals, with working familiarity with APAC frameworks (or a fast learner’s ability to build it)
• 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
• Discreet and trusted: people bring you sensitive situations because you handle them with judgment, confidentiality, and consistency
• 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
• Direct communicator: you bring leaders clear choices and a recommendation, not an escalation without a point of view
