• Maintain accurate order books and oversee customer delivery performance.
• Manage invoicing, credit notes and commercial administration activities.
• Analyse operational data and KPIs including OTIF, forecast accuracy and service performance.
• Escalate and resolve supply issues quickly while maintaining excellent customer relationships.
• Support S&OP and cross-functional planning activities.
• Drive process improvements to enhance operational efficiency and customer experience.

About You

We're looking for someone who enjoys working at the intersection of customer operations and supply chain within a regulated pharmaceutical environment.

You'll ideally have:

• Experience within the pharmaceutical, biotech, CDMO or wider life sciences industry.
• Previous experience in Customer Operations, Customer Supply Chain, Supply Chain, Sales Administration, Portfolio Management or Supply Chain Account Management.
• Experience managing customer forecasts, order books and supply planning activities. Strong understanding of OTIF, forecasting, inventory and service KPIs.
• Experience working cross-functionally with Supply Chain, Commercial, Finance and Manufacturing teams. Excellent stakeholder management and communication skills.
• Strong analytical ability with confidence using Excel and CRM/ERP systems.
• A proactive approach with the ability to manage multiple priorities in a fast-paced environment.

Why Apply?

This role offers the opportunity to join a growing international pharmaceutical organisation where you'll have broad operational ownership rather than working within a narrowly defined function. You'll work across multiple markets, collaborate with senior stakeholders and play a key role in improving customer service, forecasting and supply performance while helping shape future operational processes.
