Some engineering opportunities focus on maintaining mature products.

Others provide the opportunity to help design, develop, validate, and improve highly engineered products that operate in some of the most demanding industrial environments in the world.

This opportunity falls squarely in the second category.

Our client is expanding a specialized engineering organization responsible for the design, development, testing, and continuous improvement of large AC traction motors and generators used in heavy industrial electric drive applications.

These are not commercial products.

These are large-scale rotating equipment systems measured in hundreds of kilowatts and megawatts where reliability, durability, manufacturability, and performance are critical.

We're seeking a Principal Electrical Motor Design Engineer who wants to be involved in the complete product lifecycle, from concept development and electromagnetic design through manufacturing support, testing, validation, and continuous product improvement.

You'll join a highly experienced engineering team focused on electric drive technology, rotating equipment, and next-generation motor and generator development.

This role offers the opportunity to work closely with mechanical engineers, manufacturing personnel, testing teams, drafting resources, and technical leadership while helping advance strategically important electrification initiatives.

If you're looking for an opportunity where your work gets built, tested, and improved in real-world environments, this role deserves your attention.

Unlike many engineering roles that focus on a narrow portion of the product lifecycle, this position offers broad ownership and direct involvement from concept development through manufacturing, testing, validation, and continuous improvement.

• Ownership across the entire product lifecycle
• Direct interaction with manufacturing and testing teams
• Exposure to large-scale motors, generators, and rotating equipment
• A highly collaborative, low-ego engineering culture
• Strong technical leadership and mentorship
• Meaningful influence on product design and engineering decisions
• Variety of work spanning design, manufacturing support, testing, troubleshooting, and product improvement
• Long-term technical and leadership growth opportunities

• Lead electromagnetic design of large AC traction motors and generators
• Define motor performance requirements including torque, efficiency, thermal performance, and durability
• Develop stator, rotor, winding, insulation, and cooling system designs
• Perform electromagnetic analysis and design optimization
• Support prototype development and production implementation
• Partner closely with manufacturing teams to improve quality and producibility
• Support testing, validation, and performance analysis activities
• Investigate root cause and reliability issues
• Analyze test data and drive continuous improvement initiatives
• Provide technical leadership on complex rotating equipment programs

• Bachelor's degree in Electrical Engineering or related discipline
• Significant experience designing large AC motors, generators, or related rotating equipment
• Experience supporting products through manufacturing and testing
• Strong knowledge of electromagnetic design principles
• Understanding of insulation systems, cooling…
