Role Summary

The HR Associate supports the HR Manager in delivering responsive, accurate and practical HR services for the US office across the full employee lifecycle. This role is suited to an HR professional with 3–5 years of experience who can independently manage routine HR activities, coordinate recruitment and onboarding, maintain reliable employee data, and support payroll, benefits, learning, performance and employee engagement.

The role serves as a first point of contact for employees, providing guidance on established policies and processes within agreed authority. It requires sound judgement, discretion and accountability, with complex employee relations matters, policy exceptions and decisions requiring approval escalated to the HR Manager.
