Job description

I'm partnering with a fast-scaling, globally connected tech business that's carving out a bold new chapter. They're growing, transforming, and acquiring and they need a confident, commercially sharp HR Business Partner to sit at the heart of it all.

This is a role for someone who genuinely enjoys being in the room - influencing leadership, shaping people strategy, and rolling up their sleeves when needed. You'll be based in their Mayfair office five days a week, working closely with UK and international leadership teams as the business continues to integrate new acquisitions and build a unified, high-performing culture.

What you'll be doing :

• Acting as a trusted partner to UK and European leaders, providing pragmatic guidance across the full people agenda.
• Leading on M&A activity - due diligence, integration, harmonisation, culture alignment.
• Owning UK ER, performance, onboarding / offboarding, and policy governance.
• Driving people programmes that support scale, structure, and organisational clarity.
• Ensuring UK employment law compliance with a confident, commercial lens.
• Partnering with global HR teams across the US, India, and APAC to deliver aligned initiatives.
• Using data and insight to support decision-making and influence senior stakeholders.

What they're looking for :

• Strong HR generalist / BP experience within fast-paced, evolving environments - 5-8+ years of progressive HR experience, including at least 3 years in a business partner or generalist capacity.
• Demonstrable M&A exposure - this is essential.
• Confident handling UK employment law and complex ER with maturity and judgement.
• Someone who thrives onsite, collaborative, visible, and ready to shape culture in real time.
• Exceptional stakeholder management - credible, composed, and commercially minded.

Why this role?

You'll be joining a business at a genuinely pivotal point - high growth, high ambition, and a leadership team that values HR as a strategic partner. If you're energised by structure-building, influencing senior leaders, and driving people strategy through change and acquisition, this is a brilliant next step.
