This is an opportunity for an accomplished HR leader who thrives in a fast-paced environment, enjoys solving complex people challenges and can quickly establish credibility with senior stakeholders.

• Leading the delivery of high-quality People services across the business.
• Partnering with senior leaders on organisational, people and commercial challenges.
• Managing complex employee relations matters and organisational change.
• Leading, coaching and developing the People team.
• Driving continuous improvement across People processes and systems.

What we're looking for

You'll be an experienced HR professional who can quickly build trust and make an immediate impact.

You'll bring:

• Significant experience operating at Senior HR Manager or Head of HR level.
• Strong generalist HR expertise across the full employee lifecycle.
• Excellent employment law knowledge.
• Proven experience managing organisational change.
• Outstanding stakeholder management and influencing skills.
• Confidence working with ambiguity and shifting priorities.
• Experience leading and developing HR teams.
