Avidity Group is the parent company of 5 specialist agencies who offer a range of services to help brands sell more.  We’re proud to partner with some of the UK and Ireland’s most recognised and well-loved brands, supporting them to grow faster, sell smarter and stand out in competitive markets. 

Reporting to the Group People Director and sitting on the People Leadership Team (PLT), this is a key role with real visibility and influence across the business.

You’ll lead a talented team responsible for payroll, HR systems and data, administration, and reward – ensuring we deliver a seamless, high-quality service to colleagues across the Group.

This is a fantastic opportunity to combine hands-on operational leadership with strategic impact, helping shape the future of our people services. 

What you’ll be doing

As HRSS Manager, you’ll play a pivotal role across a number of areas:

HR Operations (Payroll, Systems & Administration)

• Oversee the end-to-end payroll process, supporting your team to deliver when required
• Take ownership of our HR systems, driving continuous enhancement, optimisation and efficiency
• Lead the delivery of regular and ad hoc reporting, and ownership of our people data and providing meaningful insight
• Manage key cyclical activities such as gender pay gap reporting, engagement surveys, board reporting, benefits renewals, system renewals and pension audits
• Chair and lead the Group Remuneration Committee (RemCom)
• Own and manage supplier relationships on our reward and benefits offering

What we’re looking for

We’re looking for someone who brings both expertise and energy to the role:

• Strong, hands-on experience of end-to-end payroll — UK essential, Ireland highly desirable
• Experience working with and influencing stakeholders at all levels (internal and external), with examples such as leading governance forums (e.g. RemCom)
• Strong knowledge of HR systems and data, including configuration, optimisation and reporting
• Proven experience leading a team in a fast paced, complex environment
• Experience in reward and compensation processes, particularly from an operational perspective
• A track record of driving process improvement and delivering operational excellence

Experience within retail or an agency environment would be highly advantageous, alongside a track record of managing budgets, driving change and developing policies. 

Skills & capabilities

• Exceptional attention to detail with a strong focus on accuracy
• Clear, confident communicator with the ability to influence and build relationships
• Highly organised, with the ability to prioritise and meet deadlines
• A data-driven mindset, able to interpret and present insight effectively
• Advanced Excel skills (e.g. Pivot Tables, VLOOKUP)
• A forward-thinking, AI-curious mindset, with an interest in automation and efficiency
• Comfortable switching between hands-on operational delivery and strategic discussion

Why join us?

This is a great opportunity to take ownership of a critical function, influence at a senior level, and shape how HR Services evolve across Avidity. You’ll be joining a collaborative People Leadership Team, playing a key role in delivering both operational excellence and continuous improvement.  With colleagues based across the UK and Ireland, we’re proud of our collaborative, people-first culture.
