We are partnering with a private equity-backed technology business to appoint an Interim Senior HR Business Partner to support a critical operations transformation programme.

This is a high-impact role embedded within a business undergoing rapid growth and significant change, driven by investment and a focus on automation, AI-led service delivery and operational efficiency.

The opportunity...

You will act as a senior, hands-on HRBP aligned to Operations (c.600 FTE), leading the people agenda for a large-scale transformation programme.

This is not a traditional advisory role — you will be responsible for owning and delivering change end-to-end, working closely with senior operational and transformation leaders.

Key responsibilities...

  • Lead organisation design and workforce planning, defining the future-state operating model
  • Translate strategic transformation goals into practical, deliverable people plans
  • Deliver restructuring programmes, including consultation and redundancy processes
  • Partner closely with Operations leadership to drive efficiency and cost transformation
  • Own the people communication strategy, maintaining engagement through change
  • Provide credible challenge and insight to senior stakeholders
  • Ensure alignment between HR, Operations and Transformation teams

The Context...

  • High-growth, PE-backed technology environment
  • Significant transformation agenda focused on automation and systems implementation
  • Operations population of circa 600 employees
  • Likely workforce evolution including role redesign and reduction (c.70–100 roles)
  • Fast-paced, evolving environment with strong leadership visibility

What we’re looking for...

  • Experienced Senior HRBP / Transformation HR Lead (ideally within Technology)
  • Proven track record delivering organisation design, workforce planning and restructuring
  • Must have experience in PE-backed, high-growth or complex transformation environments
  • Strong employee relations expertise, including consultation processes
  • Highly commercial, pragmatic and delivery-focused
  • Comfortable operating hands-on at pace in ambiguous environments
  • Confident influencing and challenging senior stakeholders

Why apply...

  • Opportunity to lead a business-critical transformation programme
  • High visibility with senior leadership and transformation teams
  • Work within a fast-growing, PE-backed business
  • Immediate start with strong day rate

If you’re an experienced HR transformation specialist who thrives in fast-paced, delivery-focused environments, we’d love to hear from you.
