Mechanical Engineer Switchgear and Power Systems

Job Description

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 switch gear, 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.

• Develop electrical and mechanical designs for switch gear, 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

• Bachelor’s degree in Mechanical Engineering or related field
• 3 to 6 years of mechanical engineering experience, preferably with switch gear 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

• Strong proficiency in 3D CAD modeling and assembly creation
• Experience with switch gear 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

• Deep familiarity with low‑ or medium‑voltage switch gear 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, Solid Works, or AutoCAD
• Exposure to ERP systems such as Net Suite
