STADA UK Thornton & Ross – Senior Microbiologist

Huddersfield |U.K.| Full-time | Permanent

Step into a high-impact Senior Microbiologist role at the heart of pharmaceutical manufacturing, where your expertise directly safeguards patient safety and product quality. You’ll be the go‑to specialist on site, applying advanced microbiological knowledge to product testing, the cleanroom and production environment, and key quality systems — ensuring every batch meets the strict demands of cGMP, GLP, Data Integrity and Microbiological Investigation Procedures, and enabling confident, timely product release.

Working with a high degree of autonomy, you’ll own your projects and consistently hit daily and weekly deadlines, while acting as a senior leader within the Microbiology team. You’ll assign and monitor tasks for other Microbiology staff, support robust environmental and utility monitoring programmes, and partner closely with the Microbiology Supervisor on workload review, reporting, and cross‑site communication in line with the relevant Pharmacopoeia. This is a role where your technical judgement shapes manufacturing decisions — and the data you generate helps get life‑changing medicines to patients.

How You Will Make An Impact

• Lead microbiology operations to the highest standards of cGMP, GLP, ALCOA+ Data Integrity and laboratory safety, setting the benchmark for compliant, reliable testing.
• Own site-wide microbiological monitoring — overseeing sampling and analysis of environments, water systems, raw materials, products and stability samples using Pharmacopoeial methods.
• Interpret complex data, drive timely certificates of analysis and LIMS entry, and lead investigations through to robust, well-documented conclusions.
• Spot risks and opportunities in processes, methods and data, championing validation, method improvement and continuous improvement across the lab.
• Act as a senior technical and people leader — mentoring Microbiology staff, balancing workloads and deputising for the Microbiology Supervisor while keeping plans on track.
• Be a visible microbiology expert across the site, presenting clear data and regulatory positions, maintaining a controlled aseptic environment, and living company values in every interaction.
