How You Will Make an Impact

As a Plastics Process Development Engineer, you will lead the development, optimization, and validation of molding processes that support Thermo Fisher Scientific’s portfolio of innovative plastic products used in life science and laboratory applications. You will leverage your deep technical expertise in Scientific Injection Molding (SIM), Design of Experiments (DOE), and process validation to deliver robust, repeatable, and efficient molding processes that meet demanding performance and quality requirements.

Your work will directly impact Thermo Fisher’s ability to deliver high-quality consumables that enable scientists worldwide to achieve breakthrough results.

What You Will Do

• Lead process development activities for new and existing injection molded components from concept through commercial production.
• Apply Scientific Injection Molding (SIM) principles to establish, optimize, and control molding parameters for consistent part quality.
• Develop and execute Design of Experiments (DOE) to evaluate process variables, establish control windows, and identify critical process parameters.
• Partner cross-functionally with tooling, quality, materials, and manufacturing teams to ensure seamless product launch and scale-up.
• Support tooling design and qualification, including review of gating, venting, cooling, and part ejection systems.
• Lead and document process validation activities (IQ/OQ/PQ) in alignment with Thermo Fisher Scientific’s quality systems and industry standards.
• Perform advanced troubleshooting of molding processes and equipment to resolve performance issues and drive continuous improvement.
• Provide technical mentorship and guidance to process technicians and junior engineers.
• Generate detailed technical reports, protocols, and documentation to support validation and regulatory submissions.

Keys to Success

Education

• Bachelor’s degree in Plastics Engineering, Mechanical Engineering, Polymer Science, or related discipline.
• Master’s degree preferred.

Experience

• Minimum 7 years of experience in injection molding process development, optimization, and validation.
• Proven track record applying Scientific Injection Molding (SIM) principles in a production environment.
• Demonstrated proficiency with Design of Experiments (DOE), process characterization, and statistical analysis tools.
• Extensive experience developing processes for high-precision, tight-tolerance plastic components.
