Primary Duties & Responsibilities

• Responsible for manufacturing engineering support, process development, production readiness, pilot build execution, and scale-up planning for advanced thermal management products.
• Lead and support manufacturing activities for semiconductor packaging hardware, liquid cold plates, thermal spreaders, advanced ceramic/diamond materials, embedded cooling structures, and related thermal assemblies.
• Develop manufacturing process flows, routings, work instructions, inspection plans, tooling requirements, and process control methods.
• Support transition of development processes into controlled manufacturing processes.
• Work with engineering and operations to identify manufacturability risks, process gaps, yield issues, cost drivers, and capacity constraints.
• Support pilot builds, customer qualification builds, and early production builds.
• Coordinate with internal teams, suppliers, and external processing partners on machining, polishing, metallization, bonding, joining, cleaning, inspection, testing, and final assembly.
• Support make-vs-buy analysis and supplier readiness for critical manufacturing steps.
• Drive yield improvement, cycle-time reduction, cost reduction, and process repeatability.
• Support root cause analysis and corrective actions for manufacturing defects, process variation, supplier issues, and customer build issues.
• Partner with quality and reliability teams to ensure manufacturing processes support customer qualification and product requirements.

• Support capital planning, equipment selection, process validation, and manufacturing readiness reviews.

  Education & Experience
