Mechanical Engineer

Principal Motor Design Engineer (Mechanical Engineer)

This role serves as the principal technical leader for the design, development, and qualification of advanced electric motor systems that support next-generation aerospace and defense platforms. You will own the full motor development lifecycle for high-performance Permanent Magnet Synchronous Motors, Brushless DC motors, and AC synchronous machines used in mission-critical applications. Acting as the senior technical authority, you will translate complex system requirements into innovative, manufacturable, and highly reliable motor solutions while guiding multidisciplinary teams through requirements development, modeling and simulation, prototype manufacturing, qualification testing, certification, and production release.

Responsibilities

• Lead the end-to-end design and development of advanced electric motor systems for aerospace and defense applications, from concept through production release.
• Serve as the principal subject matter expert for Permanent Magnet Synchronous Motors, Brushless DC motors, AC synchronous machines, and related electric machines.
• Translate system-level requirements into detailed motor specifications, ensuring performance, reliability, and manufacturability for high-reliability environments.
• Evaluate motor designs as integrated electromechanical systems, balancing electromagnetic performance with mechanical integrity, thermal management, structural durability, rotor dynamics, bearing design, material selection, and drivetrain integration.
• Perform detailed modeling, simulation, and analysis of electric machines using ANSYS Motor-CAD and related tools for electromagnetic, thermal, structural, and mechanical behavior.
• Develop and review CAD models, engineering drawings, GD&T, tolerance stack-ups, and dimensional fits for precision rotating assemblies.
• Guide designs through the complete product lifecycle, including requirements review, specification development, concept design, detailed analysis, CAD and drawings, prototyping, test, qualification, and transition to production.
• Collaborate closely with multidisciplinary engineering teams, providing technical leadership, mentoring, and strategic direction to ensure successful program execution.
• Define and oversee motor test and qualification plans, ensuring compliance with applicable aerospace and defense standards and customer requirements.
• Assess and select materials for high-performance electromechanical hardware, ensuring compatibility, durability, and performance in demanding operating environments.
• Integrate motor designs with drive electronics, applying a strong understanding of motor control fundamentals and system-level interactions.
• Conduct troubleshooting and root-cause analysis for motor and system-level issues, using first-principles engineering to resolve technical challenges.
• Prepare clear technical documentation, reports, and presentations that communicate design rationale, analysis results, and test findings.
• Present technical designs and analyses in internal design reviews and to customers and government stakeholders, effectively defending technical decisions and trade-offs.
• Ensure designs and development activities align with relevant aerospace and defense standards, including MIL-STD-810, MIL-STD-461, MIL-STD-704, AS9100, and related requirements.

Essential Skills

• Bachelor's degree in Electrical Engineering, Mechanical Engineering, Electromechanical Engineering, or a closely related field.
• 10+ years of experience designing electric motors, rotating electromechanical systems, or other high-performance machinery, preferably in aerospace, defense, or similar high-reliability industries.
• Demonstrated expertise in Permanent Magnet Synchronous Motors, Brushless DC motors, AC synchronous machines, or similar electric machine designs.
• Strong understanding of magnetic circuits, winding design, motor losses, efficiency, torque production, and thermal management in electric machines.
• Hands-on proficiency with ANSYS Motor-CAD for motor design and analysis.
• Experience using ANSYS or equivalent tools for electromagnetic, thermal, structural, and mechanical analysis of electric machines…
