About Urban Gym Group

Urban Gym Group is a fast-growing, multi-brand fitness organization committed to providing innovative and inspiring fitness experiences. With locations across the Netherlands and the United Kingdom — including TrainMore, Gymbox, Clubsportive, The CLB, RUSH, PILAT3S, TRIB3, and Gym Warehouse — we are dedicated to empowering people to live healthier, happier lives. We value teamwork, innovation, and a passion for fitness, and we’re looking for an Interim Payroll specialist who can keep our payroll running smoothly from day one.

Job overview

The Interim Payroll Specialist will ensure smooth, accurate, and timely monthly payroll processing for all Urban Gym Group employees across the Netherlands and the UK and potential other European countries, while also supporting the transition to a new payroll and ERP system and end-to-end payroll flow. This role combines hands-on operational delivery with active involvement in the implementation project: you’ll keep the lights on month-to-month and contribute to the work that will set up the function for the future. You’ll work closely with the Finance Director, the HR team, and our external payroll providers.

The role has a strong operational focus and requires hands-on experience in managing payroll in a dynamic environment with a large operational workforce, including flex workers and zero-hours contracts across club operations. In addition, the role will support the integration of newly acquired entities into the Group’s payroll processes and systems, including the transition and harmonization of payroll activities previously managed outside the Group.

Goals of the role

1. Run smooth, accurate monthly payroll for all Urban Gym Group clubs in the Netherlands and the UK: no surprises, no delays, employees paid correctly and on time, every month.
2. Support the transition to a new payroll system and flow: contribute to scoping, implementation, parallel runs, go-live, and adoption — so it lands on time and without disruption to monthly payroll.
3. Onboard international payroll provider and transition from the current payroll provider
