Job Summary: 

New product development:

Take design concept of prospective product and turn it into a manufacturable product. Generate all design documentation that defines and supports how the prototype and/or final product are to be built.  Support in building and testing of prototype and/or final product in order to validate the concept and/or function of the product meets Deliverables. Use results of prototype/final product testing to make any changes necessary to meet all design objectives of product.  Revise engineering documents to reflect these changes.

 Sustaining Engineering:

Support all required aspects of existing product enhancement, from improving build process efficiency, cost reduction alternatives, reliability improvements, and customer and service support. This also entails Sales support tasks from a technical standpoint.

 Essential Job Duties and Responsibilities:(Additional duties may be assigned)

  •  Prepare engineering documentation for all projects such as Electrical schematics, P&ID (Process & Instrumentation diagram), BOM’s (Bill of Materials), Design assumptions, MS (Mechanical Schedule), SOO (Sequence of Operation), etc.


  • Perform thermodynamic modeling on refrigeration systems for new products for the purpose of selecting refrigeration components used to build these products. Components specified include: Compressors, heat transfer coils, refrigeration system components (such as expansion device, receiver, filter-drier, etc.), air moving components, such as motors, fans, impellers, etc.  
  • Research and analyze data such as client design proposals, specifications, and manuals to determine feasibility of design or application. 
  • Evaluate field installations and applications and recommend design modifications required to eliminate/correct machine or system malfunctions. 
  • Assist test engineer during testing phase on prototypes of new products. 
  • Collaborate with manufacturing to revise design of products and parts used in the building of these products so as to improve cycle time and product cost. 
  • Meet with vendors to discuss improvements and updates to their product lines for the purpose of keeping up to date with new technology. 
  • Participate in engineering meetings and meetings with other departments as needed to discuss how to best introduce new products into manufacturing and also meet cost targets for these products.
