Role: People Administrator - 6 Month Fixed Term Contract

Location: London, United Kingdom

About the role: 

The People Administrator is a specialist within Oliver's People team, responsible for comprehensive HR operations across UK and EMEA. This is a role for someone who brings solid HR foundations and wants to grow within a dynamic, international team. You'll manage the full range of employee lifecycle documentation, support People Partners across core cyclical activities, and take ownership of projects as your expertise grows. Alongside the day-to-day, you'll help ensure our processes are globally aligned, audit-ready, and continuously improving.

What you will be doing: 

HR Operations & Administration

• Manage employee documentation across the full lifecycle — offer letters, contracts, contract variations, and all relevant correspondence.
• 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.

Employee Lifecycle & Onboarding

• Coordinate new starter administration, inductions, and background or reference checks.
• Ensure right-to-work and data protection compliance across UK and EMEA markets.
• Continuously refine internal workflows for onboarding, offboarding, and all lifecycle events.
• Guide employees and managers through family leave processes, including maternity, paternity, and adoption.

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.
• Confidence drawing insights from HR data, reports, and metrics.
• 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.
• An agentic approach — you break down complex tasks and find efficient solutions independently.
• Ability to critically evaluate AI outputs and apply human judgement before acting on them.
