Job description

Description

Position Summary:  The duties of a Mechanical Engineer will primarily consist of designing and developing products in the load bank and fuel supply lines to meet the exacting requirements of our customers. Proficiency will be attained on the job including the acquisition of a working knowledge of our products and the application of them. This is a technical position involving engineering knowledge and application of that knowledge to interpret requirements and develop design solutions. The engineer is expected to grow quickly in knowledge and ability to the point of assuming independent work in a period of 3-6 months and demonstrate continual growth thereafter.  



Key Responsibilities:

  • Work closely with the Engineering Manager and other senior engineering personnel to complete design work assigned in a timely manner 
  • Analyze sales orders and customer specifications to design equipment consistent with customer requirements
  • Analyze designs to verify equipment adherence to ASME, UL, NEMA, or other applicable specifications
  • Create detailed engineering drawings and documentation to support the manufacturing of industrial equipment
  • Accurately enter and manage design information within proprietary software systems


This is not intended to be a comprehensive list of job duties. Other job related responsibilities will be assigned as needed. 


Requirements

  • Technical background including education and/or experience equivalent to 4 year degree in Mechanical Engineering
  • Strong attention to detail
  • Thorough understanding of mathematics and mechanical design principles, as well as a basic understanding general principles in electrical systems and sheet metal design and manufacturing 
  • Ability to create and maintain detailed 2D and 3D CAD models and drawings. Familiarity with AutoCAD and/or SolidWorks - design simulation experience or CAD software certifications are a plus 
  • Ability to identify (through both observation and conversation) key requirements needed to develop products that will meet the demands of our customers
  • Moderate computer skills including familiarity with Office and ability to learn proprietary software quickly and accurately 
  • Problem solving skills and ability to work effectively under demanding deadlines
  • Ability to remain seated and work from a computer for extended periods of time
  • Ability to receive and retain instructional information 
  • Must be able to communicate (read, write and speak) the English language clearly
