Brendan Thomas

Salary: $110,000 - $135,000 per year

This is a confidential search on behalf of a well-established, multi-site product design and engineering firm with deep expertise in bringing complex electro-mechanical and plastic products to market. The company partners with global brands and manages the full product development cycle — from ideation through production launch — across a range of end markets including consumer electronics and medical devices.

Why This Role Stands Out:
You'll own the full product design lifecycle — from early concept to tooling validation to medium-volume production — and serve as the definitive technical authority on plastic part and electro-mechanical assembly design across two engineering sites.

• Work on real products that ship — 10,000 to 100,000 units per year, across industries including consumer and medical device applications
• Collaborate with a global design team, including support engineers in Taiwan and a worldwide supplier network
• Two-site presence across the Kansas City metro and St. Louis metro areas — variety, visibility, and impact
• Mentor the next generation of engineers and set the bar for CAD standards and DFM best practices
• Join a well-resourced, product-focused company where engineers are respected as core contributors to business outcomes

Required:

• B.S. in Mechanical Engineering, Plastics Engineering, or related field
• 10+ years of hands-on product design experience with a strong focus on plastic injection molded parts
• Expert-level 3D CAD proficiency — Solid Works preferred;
  Creo or NX considered
• Deep understanding of injection mold design, moldflow analysis, and tooling processes
• Experience with assembly design techniques: fasteners, snap-fits, adhesive bonding, ultrasonic welding
• Proven track record of launching products in medium-volume production environments (10k–100k units/year)
• Strong FEA and structural analysis skills — using simulation to optimize design, not just validate it
• Ability to travel regularly between the Kansas City metro and St. Louis metro engineering sites

• Experience with additional plastic processes: blow molding, thermoforming, or extrusion
• Familiarity with materials used in medical device applications, including skin-contact-rated materials
• Exposure to various metal fabrication techniques: machining, casting, extrusion, bending/forming

• Competitive salary
• Comprehensive medical, dental, and vision coverage
• 401(k) with company matching
• Company-paid life insurance
• Short- and long-term disability insurance
• Flexible Spending Account (FSA) / Health Savings Account (HSA)
• Generous paid time off
• Employee Assistance Program (EAP)
