Job Description

Are you looking for a meaningful new opportunity to test and growth your technical skills? We have an immediate need for a Process Development Scientist - Computational Fluid Dynamics to join AML’s Process Development Organization. This is an outstanding opportunity to seek a variety of challenges and responsibilities in support to our manufacturing facility at Amgen Manufacturing Limited in Juncos, Puerto Rico.

The Role

The role of the Process Development Scientist - Computational Fluid Dynamics is to monitor, predict, optimize and address wide variety of multiple challenges in manufacturing processes by applying modeling for pressure and open systems, control volume analysis; mass and momentum conservation for moving fluids; viscous fluid flows, flow through pipes/tubing; heat transfer behaviors, dimensional analysis and boundary layers. Develop innovative models necessary to study, analyze, and design fluid dynamics through the application of these concepts. With the intention of developing problem-solving skills essential to good engineering practice of fluid mechanics in practical applications in support of Drug Product manufacturing facilities of oral dosage form and parenteral products. The candidate should write papers and help AMGEN with technology development, patents, among others. The scope includes all process stages from formulation, filling, inspection, assembly, and packaging. The candidate will develop a deep understanding of the operations to become a subject matter expert to support activities including new product introduction, commercial support, improvement of existing processes and acquisition on new technologies. The candidate will have good documentation skills to write reports that can be used in regulatory audits.
