As an HR Assistant, you'll join our friendly and supportive People Services team, the first point of contact for a wide range of HR queries across the business. Whilst we're a small team, we're a busy one, providing essential support throughout the employee lifecycle.

What You'll Be Doing

• Preparing and processing offer letters and employment documentation.
• Completing HR compliance checks, including right to work verification and pre-employment screening.
• Supporting the onboarding of new starters, as well as coordinating internal moves and leavers.
• Responding to a wide range of employee queries, including absence management, annual leave, family leave and HR system support.
• Working closely with colleagues across HR and Payroll to resolve queries efficiently and provide a seamless employee experience.
• Building positive relationships across the business through clear, professional and effective communication.
• Providing administrative and project support for wider HR Operations initiatives and improvement projects

• A professional, approachable and confidential manner, with the ability to handle sensitive information appropriately.
• Strong attention to detail and the ability to work accurately and efficiently.
• Excellent communication and relationship-building skills, with the confidence to support colleagues at all levels across the business.
• A collaborative approach and willingness to share ideas, knowledge and best practice with the wider team

• Two paid volunteering days every year to support causes that matter to you.
• Access to a range of colleague discounts and lifestyle benefits to support you both inside and outside of work.

We also offer a wide range of well-being initiatives to encourage positive mental health both in and out of the workplace and to make sure you're fully supported.
