Role Overview And Responsibilities

The Principal Process Development Engineer will lead the development, optimization, and validation of manufacturing processes for electromagnetic assemblies used in medical products, including sensors, motors, coils, and electromagnetic subsystems. In addition to developing scalable and compliant production methods, this role includes mechanical engineering responsibilities related to product design, device integration, tooling, and system performance. The engineer will collaborate closely with R&D, Quality, and Manufacturing to drive innovation, reliability, and efficiency in product realization.

• Lead development and validation of manufacturing processes for electromagnetic components such as coils, solenoids, actuators, and integrated assemblies in medical products.
• Develop robust, scalable, and cost-effective processes including coil winding, soldering, potting, encapsulation, EMI shielding, and thermal bonding in medical products.
• Design process fixtures, tools, and jigs to support precise assembly and alignment of electromagnetic components.
• Implement automated and semi-automated solutions for high-complexity assemblies.
• Lead equipment selection, installation, and qualification (IQ/OQ/PQ).
• Conduct process feasibility studies, risk assessments (PFMEA), and design of experiments (DOE).
• Collaborate with R&D, Quality, and Manufacturing teams to ensure manufacturability and regulatory compliance.
• Identify and implement cost-reduction and process optimization opportunities.
• Interface with suppliers and contract manufacturers on process capabilities and technology transfers.
• Support design and testing of mechanical components and subassemblies used in electromagnetic medical devices.
• Apply mechanical design principles, including DFM/DFA, GD&T, stress/thermal analysis, and materials selection.
• Participate in failure analysis and root cause investigations for process- and design-related issues.
• Serve as the technical lead in cross-functional teams through concept development, design transfer, and production phases.
• Generate and maintain technical documentation including work instructions, SOPs, PFMEAs, process flow diagrams, and validation reports.
• Mentor junior engineers and act as a subject matter expert in electromagnetic and mechanical process development.
• Partners with the Sales team and outside customers for specific designs and new business opportunities.
• Assists in building product prototypes and production process debugging.
• This position requires approximately 20% sales-oriented travel and a consistent on-site presence.
• Other duties as required and/or assigned.
