- Develop a more predictive, risk-based approach to microbiological monitoring and control
- Define KPIs and reporting frameworks for microbiological performance at group level
- Influence the adoption of digital systems and tools to enhance data visibility and decision making
Cross-Functional Influence
- Partner with Operations, Technical, NPD, and Commercial teams to embed microbiological risk management across the product lifecycle
- Provide technical input into process design, factory layouts, and capital investment decisions
- Act as the microbiology lead in customer and regulatory interactions where required
Skills & Experience Required
