We pride ourselves on combining expert HR knowledge with genuine care for our people and our clients.
What You’ll Do
In this varied and rewarding role, you’ll support both internal teams and 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 both our internal colleagues and clients receive an exceptional HR service.
Your responsibilities will include:

- Prepare and issue employment contracts, offer letters, and HR correspondence for both internal and client employees.
- 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 for internal teams and clients.
- 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, and assist internal teams with HR process improvements.
What We’re Looking For
You’ll thrive in this role if you:
- 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.
