• Administer compliance casework, including probation, absence, disciplinary, grievance, performance management, redundancy, and TUPE documentation.
• Maintain accurate, secure, and compliant records across Sage (HRIS), Culture Amp, and Greenhouse (ATS).
• Quality‑assure your own and team‑generated documents, applying consistent attention to detail at every stage.
• Keep people processes audit‑ready, with the employee lifecycle accurately and fully documented at all times.

• Ensure right‑to‑work and data protection compliance across UK and EMEA markets.
• Continuously refine internal workflows for onboarding, offboarding, and all lifecycle events.

• Advisory & Business Collaboration
• Deliver accurate, compassionate, and professional HR guidance to managers and employees as a first point of contact.
• Partner with People Partners and cross‑functional teams to provide timely administrative support.
• Support core cyclical activities, including performance appraisals, compensation planning, and HR audits.
• Contribute actively to team meetings, sharing knowledge and collaborating across the wider People team.
• Lead on assigned projects with support from the People Operations Partner.
• Payroll & Analytics
• Action monthly payroll data transfers to People Operations and Finance, ensuring complete accuracy.
• Run reports and analyse HR metrics to deliver insights and support ad‑hoc projects.

What you need to be great in this role

• Solid, practical knowledge of HR processes and UK employment law; familiarity with EMEA markets is a plus.
• Experience administering HR documentation and managing the employee lifecycle end to end.
• Exceptional attention to detail and strong organisational skills, with the ability to manage multiple workstreams at once.
• Comfortable working with HRIS platforms; experience with Sage is advantageous.
• Clear, professional communication and a collaborative, service‑oriented approach — you handle sensitive matters with care and discretion.

• Professional proficiency in English; additional EMEA language proficiency is welcome.
• Proficiency with Gen AI tools relevant to HR and administrative work, used to improve output quality and efficiency.
• Experience building personal AI workflows to streamline how you work.
