Intern, Mechanical Engineer (Spring/Summer 2027)

The role

You will design, develop, and validate medium-voltage power electronics systems. You will design parts and assemblies using a first principles design approach through CAD, analysis, prototyping, and testing.

What you will do

• Design parts and assemblies for power converters including enclosures, plastics, heatsinks, insulators, transformers, connectors, PCBAs, bolted joints, and adhesive joints
• Employ manufacturing processes such as fastening, sheet metal bending, stamping, injection molding, diecasting, extruding, and dispensing
• Design with a first principles approach, optimizing parts through analysis
• Create 3D designs and 2D drawings using CATIA V6/3DX
• Perform hands-on work such as prototyping and testing
• Collaborate with different engineering disciplines and external partners and suppliers
• Own parts and assemblies from initial concept to high volume production

Required qualifications

• Currently pursuing a Bachelor's, Master's, or PhD in Mechanical Engineering, Mechatronics, or a related field
• Will maintain student status throughout the duration of the internship
• Strong history of designing mechanical parts or assemblies through individual or group projects
• Proficiency with at least one 3D CAD program
• Strong engineering fundamentals including a basic understanding of electronics
• Familiarity with a first principles design approach
• Excellent communication and interpersonal skills
• Ability to work independently and as part of a team
• Strong problem-solving skills and attention to detail

Nice to have

• Prior internship, co-op, or research experience in mechanical design or validation
• Experience with high volume manufacturing and processes such as fastening, sheet metal bending, stamping, injection molding, diecasting, extruding, and dispensing
• Experience with PCBAs, connectors, fuses, and other electronic components
• Experience designing outdoor-rated industrial enclosures
• Experience with FEA, CFD, multi-physics modeling, or associated software (Ansys, MATLAB, Python, Simulink, StarCCM, etc.)
• Experience with GD&T and tolerance analysis
• Experience with reliability and validation testing, as well as DFMEAs
• Experience with product lifecycle management (PLM) and controlled release processes
• Experience with medium voltage (34.5kV) or grid-related products, such as converters, switchgear, circuit breakers, insulation, and shielding
• Experience with CATIA V6/3DX
