Location: London
Job Description:

Head of HR / Aspiring HR Director | High-Growth Multi-Site Business

London | Up to £100,000 | Onsite

Sanderson King is supporting a high-growth, founder-led and investor-backed multi-site business with the appointment of a Head of HR / aspiring HR Director.

This is an opportunity for an ambitious, hands-on HR leader to take ownership of the People agenda and help build the HR function for a business entering a significant period of expansion.

We are particularly interested in candidates who have worked within multi-site, clinics, healthcare, dental, veterinary, wellness, hospitality, retail or similarly operational environments and understand the challenges of scaling teams across physical locations.

The opportunity

Working closely with the Founder & CEO and senior leadership team, you will:

  • Take ownership of the day-to-day HR function and evolving People strategy
  • Build scalable HR processes, policies, systems and ways of working
  • Support significant headcount growth and new-site openings
  • Lead workforce planning, recruitment and onboarding across multiple locations
  • Manage ER, performance, reward, engagement and retention
  • Develop managers and strengthen leadership capability
  • Help shape organisational structures as the business grows
  • Create consistency across a rapidly expanding multi-site estate
  • Develop HR data, reporting and people metrics to support better decision-making
  • Support culture and engagement through a significant period of change
  • Work closely with the Founder and leadership team on key People and organisational priorities
  • Build the HR function and team further as the organisation scales

About you

You may already be operating as a Head of HR, or perhaps you’re a strong Senior HR Business Partner / People Lead ready to step into your first overall HR leadership position.

We’re looking for someone who is:

  • Experienced within a multi-site or operationally complex business
  • Comfortable working in a fast-paced, entrepreneurial environment
  • Commercial as well as technically strong across HR
  • Able to move between strategic projects and hands-on delivery
  • Confident partnering directly with Founders and senior leadership
  • Experienced supporting growth, transformation or new-site expansion
  • Pragmatic, resilient and comfortable building rather than inheriting
  • Ambitious to develop into a broader HR Director-level role as the business grows

Experience within a founder-led, PE/VC/investor-backed or high-growth organisation would be particularly relevant.

This isn’t a role for someone looking to manage an established corporate HR function. It’s an opportunity to build, influence and grow with the business.

Location: Central London

Working pattern: Onsite – candidates must be able to commit to up to 5 days per week
