  • Deep knowledge of thermoplastic resins (COC, COP, PC, PP) and elastomers (TPE/TPU).
  • Experience with CAD (SolidWorks/Creo), PDM systems, and simulation suites.
  • Familiarity with Risk Management (ISO 14971), FMEA, and Gage R&R.

Responsibilities

  • Lead architecture and design of complex biotech consumables (injection molded plastics, over-molding, LSR, assembly techniques).
  • Drive development of fluidic and microfluidic systems, ensuring integration with instrument hardware.
  • Utilize FEA, tolerance analysis, and CFD for robust design.
  • Design for compliance with ISO 13485, FDA 21 CFR Part 820, and RUO; contribute to Design History Files.
  • Own critical subsystems from concept to high-volume manufacturing.
  • Champion Design for Manufacturing (DFM) and Design for Assembly (DFA).
  • Act as primary technical contact for external molding partners and material suppliers.
  • Identify and pursue patentable innovations in fluid handling, sealing, and consumable-to-instrument interfaces.
  • Lead root cause analysis for plastic component failures.
  • Mentor junior engineers and serve as mechanical voice in cross-functional teams.
