Advanced degree in Physics, Mechanical Engineering, Materials Science, Chemistry, Chemical Engineering, Biomedical Engineering, or similar discipline.

5 years of R&D experience.

• Lead the innovation, development and/or optimization of new manufacturing concepts, processes, and procedures for transfer to manufacturing operations.
• Champion the use of Design for Reliability and Manufacturing (DRM) and data‑driven methods through process development.
• Work with process owners and product development teams to define robust process flows for new products.
• Work with technology development to understand new process technologies for research and development towards release to manufacturing operations.
• Own requirements flow down from product design to process development, including working with process owners to disposition inputs/outputs to deliver efficient, cost‑effective and robust control and monitor strategies.
• Own equipment scouting, down selection, qualification, and characterization.
• Own process characterization and process validation activities to ensure maturity and stability of processes when released to manufacturing (DOE, TMV/Gage R&R, IQ, OQ, PQ, etc.).
• Own the interfaces and interactions between processes and determine product integration risks.
• Lead risk assessments and risk burn‑down activities for process interfaces and interactions.
• Provide input into product and process design based on an understanding of the integration risks.
• Apply statistical methods and science‑based decisions to design experiments and implement improvements.
