Description
Who We Are
Ultimate Performance (U.P.) is the world's largest globally scaled private personal training business, operating across multiple regions with a reputation for exceptional results, elite coaching, and a truly premium client experience. Backed by leading private equity firm Inflexion, we are a high-performance, growth-focused organisation with a strong commercial foundation and international reach.
We are entering an exciting next phase of growth, with a clear ambition to significantly expand our global studio footprint over the coming years. This is a pivotal moment for the business and an opportunity to contribute meaningfully to the evolution of a truly international, performance-driven brand.
The Opportunity
We have a rare opportunity within our People team for a Senior HR Advisor (Employee Relations) to play a key role in supporting our global people agenda, with a strong focus on employee relations, compliance, and manager capability.
This is not a passive or purely administrative HR role. Our HR team operates as trusted people and business partners, working closely with leaders across the organisation to ensure people decisions are fair, robust, and commercially sound. You will support, coach, and at times appropriately challenge managers, bringing credibility, empathy, and strong judgement to complex situations.
This role offers genuine autonomy and trust. You will be empowered to ma
nage your own workload and priorities, with the freedom to build strong, effective relationships with managers across the global business. It requires confidence, sound judgement, and the ability to operate independently while knowing when to escalate or collaborate.
Reporting directly to the Head of HR, and with exposure to the Chief People Officer on wider initiatives, this role provides meaningful visibility and the opportunity to develop breadth alongside depth. You will take a hands-on role in managing employee relations matters globally, supporting disciplinary processes, performance improvement plans, and terminations, while ensuring consistency and best practice across the business.
Alongside core employee relations responsibilities, you will work closely with the Learning & Development team to support manager capability initiatives. This will include identifying common themes, risks, and development needs emerging from employee relations casework, contributing to the design of manager development programmes, and supporting the creation and delivery of practical, relevant training and upskilling initiatives.
You will work as part of a close-knit, collaborative People team, with dedicated colleagues supporting onboarding, benefits administration, learning and development, recruitment, and health and safety. The team works closely with Payroll to ensure accuracy, compliance, and a seamless employee experience across the full employment lifecycle
. Within this structure, you will have clear ownership of employee relations matters and will play a key role in ensuring that offboarding processes, including exits and terminations, are handled consistently, compliantly, and in line with best practice across all jurisdictions.
This is an excellent opportunity for a Senior HR Advisor with circa 3-5 years' experience who is looking to deepen their ER expertise and progress toward an HR Business Partner or HR Manager role over time. As the business continues to scale globally, the scope and impact of this role will grow accordingly, offering genuine development, increased responsibility, and exposure to broader people strategy and leadership initiatives.
You will thrive if you enjoy pace, complexity, and working within a premium, performance-led organisation that sets high standards and values pragmatic, commercially grounded HR support.
