The Opportunity

We are looking for an Office Manager & HR Administrator to own the operational backbone of our people, recruitment, and office environment.

This role exists to remove administrative load from senior operators and ensure that recruitment, onboarding, HR processes, and office operations run cleanly, consistently, and without friction.

You will act as the operational front door for recruitment administration, people operations, and office management. You will not be responsible for hiring decisions, performance management, or strategy.

This is a high‑trust, detail‑driven role for someone who takes pride in keeping systems clean, calendars aligned, documents current, and processes moving without escalation.

What You Will Do Recruitment & Talent Operations

Own the end‑to‑end recruitment administration process across all roles, from job posting through to offer, contracts, and pre‑start readiness.

Coordinate candidate communications, interview scheduling, ATS accuracy, reference checks, and documentation to ensure a smooth and timely hiring process.

Ensure all onboarding documentation and compliance checks are completed ahead of start dates, delivering a professional, consistent candidate experience.

HR & People Operations

Maintain accurate and up‑to‑date people records, including leave, sickness, attendance, probation tracking, and review timelines.

Act as the first point of contact for day‑to‑day HR queries, documentation requests, and policy clarification.

Manage onboarding and offboarding administration, ensuring checklists, access, folders, and equipment processes are completed correctly and on time.

Ensure the smooth day‑to‑day running of the office, including supplies, facilities coordination, and general administration.

Act as the internal point of contact for building management and operational suppliers.

Maintain equipment logs, key records, supplier details, invoices, and other operational tasks that would otherwise interrupt senior focus.

Compliance & Document Control

Maintain clean, organised, and accessible HR and operational documentation across shared drives.

Ensure document version control is followed and only approved, current templates are used.

Coordinate contracts, signatures, right‑to‑work checks, and background or compliance checks as required.

Internal Coordination & Administrative Flow

Manage calendars, scheduling, and internal coordination to prevent clashes and delays.

Support onboarding meetings, reviews, and offboarding processes.

Act as the operational front door for administrative matters, ensuring senior leaders remain focused on decision‑making rather than execution.

What You Will Bring

• 2–5 years’ experience in office management, HR administration, or operations support
• Strong organisational skills with exceptional attention to detail
• Confidence managing multiple workflows without things slipping
• Clear written and verbal communication
• Comfort handling sensitive information with discretion and accuracy
• A proactive mindset that anticipates needs rather than waiting for instruction
• Strong ownership mentality with a bias for clean execution
• Confidence working in a fast‑moving, high‑standard environment

What Success Looks Like

• Run recruitment administration end‑to‑end with zero bottlenecks
• Maintain clean, accurate, and audit‑ready HR records
• Ensure onboarding and offboarding processes are consistently complete
• Keep the office running smoothly without senior intervention
• Be trusted as the operational backbone for people, recruitment, and office administration
• Absorb administrative load so senior operators remain focused on high‑value decisions
• Be recognised as a reliable, calm, and precise operator
