What are the responsibilities and job description for the Mechanical Engineer -- Switchgear and Power Systems position at JDC Power Systems Inc?
JDC Power Systems is seeking a mid-level Mechanical Engineer to join our Hackettstown, NJ office. This role focuses on the mechanical design and coordination of low- and medium-voltage switchgear, power distribution equipment, and control enclosures—with particular emphasis on electrical-mechanical integration using EPLAN and industry-standard design tools.
The position combines practical mechanical engineering with the coordination of complex electrical layouts. You will translate electrical schematics and control requirements into mechanically sound enclosure designs, verify bus bar routing and phase spacing, and ensure all components fit within enclosure constraints.
The role requires attention to detail, comfort working with incomplete or legacy drawings, and the ability to translate multiple inputs into coordinated, manufacturable designs.
Responsibilities and Duties
Develop electrical and mechanical designs for switchgear, power distribution, and control systems
Create accurate 3D CAD models from electrical schematics and mechanical requirements
Verify bus bar alignment, phase spacing, supports, and clearances within enclosures
Coordinate EPLAN layouts with 3D CAD models to ensure electrical intent is mechanically feasible
Identify and resolve dimensional conflicts between bus bars, breakers, CTs, wiring gutters, and enclosure features
Evaluate designs for manufacturability, installation access, serviceability, and maintenance clearance
Produce production-ready mechanical drawings from 3D models
Support design revisions based on manufacturing feedback, FAT results, and field conditions
Coordinate with electrical, controls, manufacturing, and field service teams
Education and Experience
Bachelor's degree in Mechanical Engineering or related field
3 to 6 years of mechanical engineering experience, preferably with switchgear or electrical enclosure design
Demonstrated experience with EPLAN (or equivalent design software), electrical schematics, and electrical-mechanical coordination
Demonstrated experience reconciling multiple drawings and reference documents into a coordinated design
Required Skills
Strong proficiency in 3D CAD modeling and assembly creation
Experience with switchgear or MCC (NEMA Class 891) systems
Solid understanding of dimensions, tolerances, and mechanical fit
Experience working with sheet metal and enclosure-based designs
Ability to interpret electrical schematics, bus bar routing, and three-phase systems
Ability to manage multiple tasks and priorities
Strong communication skills and ability to work cross-functionally
Preferred Skills
Deep familiarity with low- or medium-voltage switchgear design standards (NFPA, IEEE, NEC)
Familiarity with bus bar systems and power equipment layouts
Hands-on experience with EPLAN (or equivalent design software)
Experience with CAD platforms such as Solid Edge, SolidWorks, or AutoCAD
Exposure to ERP systems such as NetSuite
