Essential Functions: 

  • Lead and manage an internal tool shop with toolmakers and mold design engineers on staff. 
  • Lead DFM review on new product designs, identifying draft requirements, parting lines, undercuts, shut-offs, wall transitions, and tooling risks. 
  • Design and/or review injection molds for medical connector components, over-molded strain reliefs, and cable assemblies. 
  • Support tooling concepts including gating, venting, cooling, steel conditions, surface finishes, slides, lifters, and other mold actions.
  • Partner with product engineering to ensure designs are manufacturable, robust, and cost-effective. 
  • Interface with external domestic and offshore mold shops during tool design, build, debug, and qualification. 
  • Assist sustaining engineering teams with tooling-related issues, yield improvements, and design updates.

  • 10+ years of progressively responsible experience in mold design, tooling, or toolmaking. 
  • Associates' degree or higher in engineering, manufacturing, or related technical field (or equivalent hands-on experience).
  • Working proficiency with SolidWorks 3D CAD software. 
  • Ability to conduct effective DFM and tooling feasibility reviews with engineering and suppliers. 
  • Strong background in medical device or regulated manufacturing environments. 
  • Experience working with global manufacturing partners. 
  • This position is not eligible for employer-sponsored work authorization. Applicants must be authorized to work in the US without sponsorship. 

Desired Skills/Qualifications: 

  • Experience in medical connector and cable assembly mold design, tooling engineering, or toolmaking. 
  • Background as a journeyman toolmaker or significant shop floor experience.
  • Familiarity with medical validation environments (IQ/OQ/PQ awareness).

  • An opportunity to join a growing team dedicated to making a difference.
  • Competitive salary and comprehensive benefits program, including medical, dental, vision, short and long-term disability, 401(K), PTO, HSA, FSA, employee discounts, life insurance, and employee activities.
