A fast-scaling, AI-enabled technology business is hiring its first HR Business Partner to build and shape the people function from the ground up.

This is not a traditional HR role. This is a hands-on, high-impact position for someone who wants to own people strategy end to end across a business growing through acquisition, integration and rapid scale, where TUPE and post-acquisition integration will be a core part of the role.

You will work closely with the CEO and leadership team, playing a key role in how the business hires, integrates and builds a high-performance culture.

Role: HR Business Partner

Salary: £55,000 to £65,000 (London) or £50,000 to £60,000 (Birmingham)

Location: Birmingham or London, with travel to other UK sites

What you’ll be doing:

• Own the full people function across a growing, multi-site business
• Lead people integration across acquisitions, with a strong focus on TUPE processes and post-transfer integration
• Act as the go-to expert on TUPE, ensuring smooth, compliant and well-communicated transitions
• Build trust quickly with newly acquired teams and align them to the wider business
• Build and improve hiring processes to attract and secure high-quality talent quickly
• Partner with leadership on organisational design, structure and scaling plans
• Develop performance management frameworks that are clear, effective and commercially aligned
• Manage employee relations, including complex TUPE cases and integration challenges
• Create practical, scalable HR processes without over-engineering
• Act as a trusted advisor to senior stakeholders, including the CEO

What you’ll need:

• CIPD Level 5 minimum or equivalent experience
• 5 to 8 years’ experience within HR, ideally in fast-growth, multi-site or acquisition-led environments
• Strong, hands-on TUPE experience is essential
• Proven experience managing TUPE transfers end to end, not just supporting them
• Experience with employee relations and post-acquisition integration
• Experience building or shaping HR processes from scratch
• Confidence working directly with senior leadership and challenging where needed
• Ability to operate at pace and bring structure to ambiguity
• A pragmatic, hands-on approach rather than a policy-led mindset
• Interest in how technology and AI can shape people operations

This role would suit someone who has led TUPE transfers directly, enjoys the challenge of integrating teams post-acquisition, and wants to build a people function in a business where this will be a constant and critical part of growth.
