Clinical Microbiologist, Principal Scientist

Position Summary

We are seeking a motivated microbiologist to contribute to late‑stage development of candidate anti‑infective medicines. In this role you will design and oversee microbiological studies and interpret results to inform further development and regulatory submissions. You will collaborate closely with clinical teams, pharmacology, CMC, and regulatory colleagues to build data packages, troubleshoot unexpected findings, and generate clear technical reports and study documentation.

• Lead the design, oversee the execution, and interpret the results of microbiology studies to advance clinical development of anti‑infective medicines.
• Execute experimental plans by performing internal experiments and/or managing research studies with external partners to drive scientific progress.
• Troubleshoot assays and propose robust alternative approaches to meet project goals and timelines.
• Drive collaboration with cross‑functional internal teams to generate data packages and enable project decisions.
• Provide thought leadership in data collection, statistical analysis, and interpretation of experimental results to ensure informed decision‑making.
• Lead communication of study results and scientific findings through written reports, presentations, and publications.
• Author Regulatory Study Reports and manuscripts in peer‑reviewed journals; contribute to IP patent filing and regulatory document preparation.
• Maintain expert level knowledge of the latest scientific literature and methodologies, contributing to continual innovation and improvement in research practices.
• Ensure compliance with regulatory requirements, ethical guidelines, and GSK standards for data integrity, safety, and quality.

• BS with 8+ years of experience or MS with 6+ years of experience or a PhD with 1+ years of experience with the degree in Microbiology.
• Hands‑on experience with bacteriology laboratory techniques.
• Experience with microbiology regulatory (e.g. FDA, EMA) and/or standards organization (e.g. CLSI, EUCAST) guidance/guidelines.

• Experience managing research studies with external partners to drive scientific progress.
• Clear, practical problem‑solving and the ability to move experiments from concept to robust data.
• Accountability for quality and timelines, balanced with thoughtful judgement about risk and rigor.
• Demonstrated ability to translate complex microbiological data into actionable guidance for late‑stage development decisions.
• Prior contributions to peer‑reviewed publications, technical reports, or regulatory documents.
• Familiarity with clinical trial design and relevant quality systems (GLP/GCP).
• Familiarity with statistical approaches or bioinformatics tools for interpreting complex datasets.
• Experience in submission of microbiology data packages to regulatory agencies.
• Proven track record of working in matrix teams and contributing to multidisciplinary projects.
• Strong commitment to accurate documentation, data integrity, and laboratory safety.
• An inclusive approach to working with colleagues at all levels and from diverse backgrounds.
• Excellent verbal and written communication skills.
