JDC Power Systems is seeking a Junior Mechanical Engineer to join our Hackettstown, NJ office. This is an excellent opportunity for a recent graduate or early-career engineer to develop practical mechanical design skills in the switchgear and power distribution industry.
In this role, you will support the mechanical design and coordination of low- and medium-voltage switchgear, power distribution equipment, and control enclosures. Working under the mentorship of senior engineers, you will gain hands-on experience with 3D CAD modeling, drawing interpretation, enclosure design, and bus bar layout verification.
This position offers structured on-the-job training, exposure to real manufacturing challenges, and the opportunity to contribute to build-ready designs that ship to customers worldwide. You will work closely with electrical engineers, controls specialists, manufacturing, and field service teams to understand how mechanical design impacts the entire product lifecycle.
Assist in developing 3D CAD models and assemblies for switchgear and enclosure designs under senior engineer guidance
Learn to interpret electrical drawings and coordinate mechanical layouts with electrical intent
Support verification of bus bar alignment, phase spacing, supports, and clearances within enclosures
Participate in identifying dimensional conflicts and conflicts between bus bars, breakers, CTs, and other components
Support the creation of mechanical drawings from 3D models under review by senior engineers
Evaluate designs for manufacturability, assembly, and maintenance access with guidance from mentors
Attend design reviews and manufacturing discussions to understand real-world engineering challenges
Communicate findings and design questions to senior team members and cross-functional partners
Bachelor's degree in Mechanical Engineering or related engineering discipline (graduating students or recent graduates welcome to apply)
0 to 3 years of mechanical engineering experience; fresh talent with strong fundamentals preferred
Academic or internship experience with 3D CAD modeling (any platform) is a plus
Exposure to electrical concepts, tolerancing, or enclosure design is helpful but not required
