• Oversee local reward and benefits activity in partnership with our Global Reward team and external providers.
• Use people data and workforce insights to identify trends, mitigate risk and support business decisions.
• Lead and contribute to local, regional and global People projects.
• Line manage and develop an HR Advisor, ensuring high-quality HR service delivery across Belgium.

• There may also be opportunities to support the UK business as part of the role.

• Senior HR Business Partner/generalist HR experience within a multinational or matrix environment
• Professional fluency in French and English is essential, Dutch language skills would be a strong advantage
• Strong, hands‑on HR and employee relations experience across both France and Belgium
• Excellent knowledge of French and Belgian employment legislation
• Experience working with French Works Councils/CSE
• Experience managing complex ER, organisational change and consultation processes
• Confidence partnering with and influencing senior leaders
• The ability and willingness to work at both a strategic and hands‑on operational level
• Previous people management experience would be beneficial
