Principal Scientist, CMCLocation:Galway, Ireland (on-site, with occasional UK travel)About the CompanyWe're working with a pioneering cell therapy biotech developing the world's first neutrophil-based allogeneic platform to treat solid tumours. Unlike patient-specific T-cell therapies, this approach is donor-derived, scalable, and consistent, enabling it to be manufactured at scale and delivered to patients more efficiently. The therapy harnesses the natural tumour-infiltrating and tumour-killing abilities of neutrophils, which can also be engineered to enhance their anti-cancer activity.The company is entering an exciting growth phase, with itsfirst-in-human clinical trial scheduled in Galway within the next 12 months. GMP manufacturing is supported by a specialist CDMO partner in Ireland, while the wider team drives innovation, translational research, and CMC strategy. This is a rare chance to join at the point where science is translating directly into patient impact.The OpportunityThis role is a bit different from a traditional lab-based process scientist role. The platform and processes are already established. Your first focus will be to lead and overseeCMC strategy, GMP compliance, and tech transferto the CDMO in Galway. You'll act as the scientific owner of the process, ensuring the CDMO is fully compliant, data and documentation stand up to regulatory review, and that manufacturing runs smoothly.It's a senior role reporting directly to the CSO, withline management of one scientistat the start and scope to grow the team later in the year. Longer term, as the company advances its neutrophil platform, this role will expand into moreprocess-focused development work, shaping future therapies.Key ResponsibilitiesLead CMC activities and strategy for the neutrophil therapy platformEnsure GMP compliance of process and documentationOversee tech transfer to the CDMO in GalwayWrite and manage EU/IE regulatory submissionsWork cross-functionally with translational and clinical teamsReport directly to the CSOLine manage one direct report, with potential to expand the teamRequirements5+ years' CMC experience in cell therapy or biologics (ideally oncology)Strong GMP and regulatory expertiseExperience overseeing CDMOs and successful tech transfersKnowledge of EU/IE regulatory requirements for CMC submissionsLeadership or line management experienceBased in/near Galway or willing to relocate, with some travel flexibility
