The Position

As a Supply Chain Planner, you play a critical role in driving our end-to-end planning processes. You’ll own the 12-month rolling forecast, lead cross-functional alignment meetings, and serve as a key partner in balancing service levels and inventory efficiency. This is a strategic position at the heart of our S&OP process, offering a unique opportunity to influence decision-making and cross-functional collaboration across the business.

Key Responsibilities

• Balance availability, efficiency and working capital, making thoughtful, data-driven decisions that support both growth and sustainability.
• Bring clarity to complexity by identifying risks and opportunities early, and turning them into clear actions for the business.
• Act as a key partner to Sourcing and suppliers, ensuring our plans are realistic, aligned and built on strong, long-term relationships.
• Increase transparency and performance by monitoring key KPIs (OOS, DOH, delisted/obsolete stock) and sharing insights through clear, consistent reporting.

We are looking for people who are

• Comfortable working in a rapid-growth, scale-up environment where processes are still evolving
• Strong analytical thinkers with a proactive, enterprising mindset
• Clear and confident communicators, able to influence stakeholders across different functions and levels
• Naturally collaborative and energised by working with diverse teams toward common goals
• Independent, organised and able to prioritise in a fast-paced environment
• Commercially minded, results-driven and always searching for sustainable ways to improve business performance

And who bring

• 3–5 years of experience in supply chain planning or a similar role
• Advanced Excel skills and confidence working with complex data sets
• Experience with ERP systems and demand planning tools
• A completed university degree in Supply Chain, Business Administration, Economics, or a related field
• Excellent command of both Dutch and English, written and spoken
