CURRENT NEED:
We are seeking to recruit a highly experienced and technically proficient Senior Mass Spectrometry Analyst to join our Analytical R&D team on a permanent basis to lead analytical efforts focused on small molecule characterization and quantification using Waters and Agilent mass spectrometry platforms. This role is central to supporting drug development through advanced GC-MS, LC-MS/MS and HRMS techniques, contributing to method development, structure elucidation, impurity profiling, and regulatory submissions. The successful candidate will play a key role in delivering high-quality analytical support for both early and late phase development, GMP manufacturing, and customer driven projects.
This position is located at the R&D Centre in Swords, Co Dublin. The R&D Centre has co-located technical and operational expertise, including analytical expertise that supports the development and manufacture of clinical and commercial products (small molecule APIs, intermediates, RSMs and peptides).
POSITION DESCRIPTION:
The Senior Mass Spectrometry Analyst will be responsible for taking oversight of all mass spectrometry activities in the R&D group, and providing technical support for these activities, as well as developing mass spectrometry methods to support method introduction for new products. In addition, the successful candidate will provide technical support for all aspects of mass spectrometry analysis including method transfer, method qualification and method troubleshooting pertaining to the manufacture of small molecule APIs, intermediates RSMs and peptides. The successful candidate will also provide support in the day-to-day running and maintenance of mass spectrometry instruments in the AR&D laboratories. The successful candidate will need to collaborate closely with other functions, including Process R&D, Technology transfer, Quality (QA/QC), SHE and external stakeholders/customers working towards the flawless, compliant and right first-time manufacture of existing and new products. In addition, the successful candidate will provide mentorship, where applicable, to more junior analytical staff.
KEY RESPONSBILITIES:
Lead the development, optimization, and validation of GC-MS, LC-MS, LC-MS/MS and LC-HRMS methods for small molecule and peptide analysis using Waters (e.g., QDa, Xevo G2S) and Agilent (e.g., 5977B, Ultivo) instrumentation.
