• Handle complex ER matters including grievances, disciplinaries and conflict resolution.
• Oversee onboarding, talent development, L&D, succession planning and employee engagement.
• Manage compensation and benefits benchmarking, right‑to‑work compliance and skilled worker visa processes.
• Support organisational change, workforce planning and the ongoing rollout of firm‑wide people initiatives.
• Ensure GDPR compliance and maintain HR policies, procedures and systems (Workday).
