Requirements

What You’ll Bring

• Inquisitive mindset — naturally questions processes and seeks better ways of working
• End‑to‑end supply chain understanding — forecasting, demand/supply balancing, variances, inventory optimisation
• Stakeholder communication strength — credible, clear, and effective with senior leaders
• Advanced Excel capability — pivot tables, complex formulas, large‑data analysis

• Backgrounds welcomed from manufacturing, logistics, consumer goods, retail, or any product‑based industry
