Position Summary

The Senior Scientist role is a scientific and technical expert grounded in strong laboratory capabilities, supporting the Cell Therapy product portfolio. The successful candidate will bring deep hands-on experience in bioassay with demonstrated ability to design and independently execute experiments, analyze complex data, interpret results, troubleshoot assay performance, and translate scientific findings into technically sound recommendations. The role will in part perform hands-on laboratory studies to support the optimization, transfer, validation, maintenance, and investigation of QC analytical methods. Experience working in a regulated laboratory environment is desired; however, scientific depth, experimental rigor, and analytical problem-solving are the primary qualifications for this position.

Duties/Responsibilities

• Serve as a scientific subject matter expert and steward in the lifecycle of bioassay methods used for cell therapy drug products.
• Provide bioassay expertise, including cell-based potency assays, reporter gene assays, and cell counting in support of QC lab investigations. This encompasses supporting technical investigations to identify root cause and provide corrective and preventive actions, including method remediations and experimental studies at the bench.
• Design, plan and independently execute laboratory experiments with a high degree of technical proficiency, including appropriate controls, experimental design, data analysis, interpretation, and scientifically justified conclusions.
• Collaborate with multiple cross-functional teams. Contribute to the development and optimization of new and existing laboratory methods and protocols.
• Present experimental findings and progress updates to immediate team. Support the preparation of internal technical reports and presentations as appropriate.
• Support transfer of commercial methods and method validation in compliance with global regulatory requirements.
• Implement method lifecycle and method maintenance programs to support bioassay methods in support of cell therapy drug products.
• Author, revise, and review technical documents such as test methods, SOPs, trend reports, and/or investigation reports as appropriate.
• Lead project, CAPA and deviation/ investigation related tasks and/or continuous improvement efforts.
• Provide support in the authoring of the analytical sections of regulatory submissions, responding to health authority questions and to function as the method validation and method transfer expert during inspections as required.
• Partner with development organizations in the design of development and qualification studies, selection and characterization of reagents, and method optimization initiatives. Represent the function on cross-functional project teams.
• Train and mentor others on cell biology techniques, methods and procedures.
• Champion and foster a positive and successful collaborative quality culture.
• Perform other tasks as assigned.
