Over half of Diageo’s 30,000+ people work in Supply Chain and Manufacturing. It’s an intricate and sophisticated operation that’s the product of logistical, manufacturing, and technical collaborations.

You will be instrumental in guaranteeing the safety, stability, and premium quality of Diageo’s low and no alcohol products. Your expertise will protect consumer safety, uphold product integrity, and strengthen brand reputation by applying microbiological knowledge across spirit production, packaging, and innovation. You will also ensure full compliance with Diageo Quality Standards, HACCP, FSSC 22000, GMP, and all relevant regulatory requirements.

• 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.
• Perform 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.

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. 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.
• Practical experience with low and no alcohol products or other high‑risk food categories would be an advantage.

Our purpose is to celebrate life, every day, everywhere. And creating an inclusive culture, where everyone feels valued and that they can belong, is a crucial part of this.

We embrace diversity in the broadest possible sense. This means that you’ll be welcomed and celebrated for who you are just by being you. You’ll be part of and help build and champion an inclusive culture that celebrates people of different gender, ethnicity, ability, age, sexual orientation, social class, educational backgrounds, experiences, mindsets, and more.

Our ambition is to be one of the best performing, most trusted and most respected consumer products companies in the world.
