  • Self-starter, capable of maintaining project organization throughout the new product development (NPD) process.
  • Responsible for CAD component and assembly modeling, initial drawing package and engineering specification creation.
  • Properly applies GD&T and understands its effects on the manufacturability and inspection of parts and assemblies.
  • Able to generate tolerance stack-up studies for mechanical components and assemblies.
  • Perform stress/strain calculation by hand and through FEA (Solidworks Simulation).
  • Work with the cross-functional NPD team as the engineering design lead.
  • Participate in hands-on troubleshooting activities, cost-reduction activities, component evaluations and other manufacturing initiatives.
  • Collaborates with the test organization to define the testing requirements that align with customer specifications.
  • Highly adept at organizing projects from initial directives through fabrication, assembly, QC and initial production.
  • Occasional regional and international travel is required (up to 20%).

  • Solenoid or electrical machine design experience a plus.
  • Must have extensive experience selecting proper materials and finishes.
  • Experience with aerospace or defense applications is a plus.
  • Minimum of five years of experience doing detailed CAD design. Solidworks strongly preferred.
  • Experienced at performing stress/strain FEA, preferably using Solidworks Simulation. Thermal analysis/FEA is beneficial.
  • Hands-on troubleshooting and design for manufacturability experience
  • Understanding quality requirements and how they affect the design (AS9100 quality systems experience a plus). Understand how drawing specifications/tolerances may affect inspection requirements.
