Full Time
5 - 10 years of experience
Basic Purpose and Objective of the Position

This position supports the New Product Introduction (NPI) Engineering team through the programming, fabrication, building, testing, troubleshooting, and modification of prototypes along with establishing machining, methods, and tool sequences to meet required customer specifications and work instructions.

Major Responsibilities - reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions:

  • Develop/modify NC programs of medium/complex NPI projects for various types of machines such as CNC lathes, CNC mills, multi-axis machines (3, 4, and 5 axis), CNC mill/turn, wire EDM, sinker EDM, and Jig-grinding.
  • Setup and operate powered machines such as 5-axis CNC mills, CNC lathes, wire EDM, sinker EDM, Jig-grinding, and surface grinders by holding extremely tight tolerances (+/- 2 microns) to customer drawing and quality specifications. Work is done in a low volume high mix environment.
  • Establishes appropriate machining methods and tool sequences. Determines the necessary fixturing and tooling to maintain tight tolerances.
  • Possesses working knowledge of CAD (Solidworks/AutoCAD) and CAM software (Mastercam) to create efficient and repeatable toolpaths.
  • Employees will use advanced inspection equipment, ex. CMM and digital optical measuring.
  • Create and maintain job documentation files. Collects and analyzes process data and provides input to the project team.
  • Trains and assists in the development of personnel (cross-training).
  • Conduct preventative maintenance, 5S and housekeeping duties.
  • Participate in the product development process and provide input during concept development and feasibility testing.
  • Handle engineering model shop schedule in coordination with the Manager, and NPI Project leads
  • Handle engineering model shop safety program, including PPE and training requirements
  • Assess the manufacturability of new designs and provide improvement feedback to Engineers.
  • Perform other duties as required.
