This role sits at the intersection of People Operations, HR Generalist, and HR Business Partnering — covering the full employee lifecycle while also helping to shape the people practices and frameworks that will support the company as it grows.   You'll work closely with managers and employees alike: rolling up your sleeves on day-to-day HR operations, supporting recruitment and onboarding, managing employee relations, and partnering with leaders on performance and organizational effectiveness. This is a broad, varied role that suits someone who's equally comfortable building a process as they are navigating a complex ER case or coaching a manager through a difficult conversation.   What You'll Do - Serve as the primary People Team point of contact for employees and managers in the UK. - Partner with managers on employee relations matters, performance concerns, manager coaching, team effectiveness, and organizational changes. - Manage employee relations cases end-to-end, including disciplinaries, grievances, performance improvement plans, and investigations, in line with UK employment law. - Support organizational planning activities including team structures, role clarity, workforce changes, and manager effectiveness. - Implement global People programs and processes locally, ensuring they are delivered effectively and compliantly within the UK. - Coordinate local execution of performance reviews, talent discussions, compensation processes, and other cyclical People programs. - Own UK People Operations administration across the employe
