Job description

Application Deadline: 21 December 2025

Department: HR

Location: Milton Keynes

We’re looking for a detail-driven and people-focused HR Administrator to join our friendly Outsourced HR team. We currently have both full-time and part-time opportunities available, so whether you’re looking for a full-time career move or part-time flexibility, we’d love to hear from you.

At Cintra HR Outsourcing, we believe great HR should feel personal, proactive and precise. As part of Cintra HR & Payroll Services, our HR Outsourcing division provides hands‑on HR administration and employee relations support to a range of UK businesses across a broad range of industry sectors and size.

We pride ourselves on combining expert HR knowledge with genuine care for our clients and their people.

What You’ll Do

In this varied and rewarding role, you’ll support our clients with day-to-day HR administration — from onboarding new starters and managing employee records to assisting with payroll data and benefits. No two days are the same, and you’ll quickly become a key part of ensuring our clients receive an exceptional HR service.

• Be the first point of contact for HR queries from our clients and their employees.
• Manage the employee lifecycle — onboarding, contract changes, off‑boarding, and documentation.
• Prepare and issue employment contracts, offer letters, and HR correspondence.
• Check right‑to‑work documents and maintain accurate employee files.
• Collate and validate payroll data including hours, absences, and pay changes.
• Support the administration of employee benefits and liaise with providers.
• Maintain and update HR systems and generate reports on HR metrics such as absence and turnover.
• Support new client onboarding by gathering and setting up HR data.

What We’re Looking For

• Have great attention to detail and love getting things right the first time.
• Enjoy working collaboratively in a friendly, fast‑moving HR team.
• Are highly organised, methodical, and confident juggling multiple priorities.
• Communicate clearly and professionally — by email or video call.
• Maintain confidentiality and professionalism at all times.
• Are confident using MS Office (Word, Excel, Outlook, Teams).
• Ideally have experience in HR administration, payroll preparation, or working with multiple client groups.

We also welcome applications from those working towards or holding a CIPD Level 3 qualification and if you are familiar with HR software systems – that would be ideal too!

Why Join Cintra HR Outsourcing?

• A supportive, collaborative team who genuinely enjoy what they do.
• Opportunities to grow your HR career — from Administrator through to Adviser and beyond.
• Access to professional development and CIPD qualification support.
• Exposure to a wide range of clients and industries.
• A culture built on trust, flexibility, and continuous learning.
