Senior Scientist

We are seeking a Senior Scientist to join the Process Analytical Technologies (PAT) team within Analytical Enabling Capabilities (AEC). In this role, you will collaborate with a cross-functional, highly engaged team to advance the development pipeline and support commercial manufacturing. The successful candidate will lead the development, validation, and implementation of in-line, on-line, and at-line PAT solutions for both small- and large-molecule modalities. This position offers the opportunity to make a meaningful impact by advancing real-time analytical capabilities, enabling process monitoring and control, as well as supporting technology transfer and launch readiness efforts for programs progressing from early development into manufacturing.

Key responsibilities

• Develop, validate, and implement PAT methods (in-line, on-line, at-line) to monitor and control process parameters and product quality attributes.
• Support the systematic assessment and deployment of in-line, on-line, and at-line PAT methods across small- and large molecule programs.
• Deploy standardized analytical platforms to enable PAT implementation, including real-time monitoring and rapid shop-floor analytics.
• Support the scale-up activities and technology transfer of PAT applications to commercial manufacturing.
• Partner with capital project and facility teams to deploy integrated PAT infrastructure aligned with the launch preparedness strategy.
• Prepare and maintain scientific documentation and validation packages for PAT methods; contribute content for regulatory submissions.
