About the role

We're excited to offer a brand-new role with the opportunity to truly make it your own.

• Develop, validate and continuously improve microbiological test methods tailored to low and no alcohol products ensuring accurate, reliable and timely results.

• Monitor, analyse and interpret microbiological data and trends to proactively identify risks, resolve issues and implement preventive measures.

• Partner with cross-functional teams (Quality, Operations, Technical, and Engineering) to embed microbiological protocols into processes, systems and everyday culture.

• Performing routine and non-routine microbiological testing of raw materials, water, in-process samples, environment and finished low/no alcohol products using validated methods appropriate to product matrices.

About you

To be successful for this role, you have a degree in Microbiology, Food Science, or a related scientific discipline. You'll also be able to demonstrate good practical knowledge of classical microbiology techniques such as aseptic technique, serial dilution, spread plating, filtration plating, water and environmental monitoring, and GLP.

In addition, you'll have:

• Minimum 5 years practical experience in industrial microbiology, ideally within beverage, food, or pharmaceutical manufacturing.

• Proficiency in aseptic techniques, microbial identification and microbiological method development/validation.

• Good working knowledge of CIP systems and their effectiveness with a track record in trouble-shooting microbial issues.

• Ability to interpret microbiological data, trend results, and translate findings into risk-based actions.
