Position Overview

The Mechanical Engineer III is responsible for leading and supporting the design, development, and integration of electromagnetic rotating machines, including AC/DC motors and generators. This role plays a critical part in ensuring mechanical integrity, performance optimization, and compliance with aerospace standards. The ideal candidate brings deep technical expertise, hands-on experience with rotating equipment, and the ability to collaborate cross-functionally across engineering and manufacturing teams.

Key Responsibilities

• Lead or support the mechanical design and integration of electromagnetic rotating machines (e.g., AC/DC motors, synchronous and asynchronous generators)
• Design, develop, and validate mechanical components including stators, rotors, laminations, end caps, bearings, and housings
• Create detailed 3D CAD models, engineering drawings, and bills of materials for rotating machinery
• Perform mechanical analyses (e.g., FEA) to optimize performance, durability, and reliability
• Collaborate with electrical engineers to ensure alignment between electromagnetic and mechanical systems
• Support material selection for magnetic, structural, and thermal performance requirements
• Develop and execute qualification plans, including prototype builds and verification/validation testing (e.g., vibration, environmental, core loss testing)
• Ensure compliance with applicable aerospace and industry standards (FAA, EASA, MIL-STD, DO-160)
• Provide hands-on support for manufacturing, assembly, and troubleshooting on the shop floor
• Lead or contribute to root cause analysis and corrective actions for design or test failures
• Drive continuous improvement initiatives across design, manufacturing, and testing processes
• Mentor junior engineers and provide technical leadership and guidance
• Adhere to all safety protocols, 5S standards, and contribute to a strong EHS culture
• Perform additional duties as assigned

Qualifications

• Bachelor’s or Master’s degree: in Mechanical Engineering, Aerospace Engineering, Mechatronics, or a related field
• 7+ years of experience: in mechanical design and development of electromagnetic rotating machines, preferably within aerospace or a related industry
• Proven experience: supporting testing, validation, and troubleshooting of motors, generators, or similar systems
• Proficiency in 3D CAD software: (e.g., CATIA, SolidWorks)
• Strong knowledge: of GD&T and mechanical analysis tools (e.g., ANSYS or similar FEA software)
• Solid understanding: of material properties relevant to electrical machines, including magnetic, thermal, and structural considerations
• Working knowledge: of electromagnetic principles and their interaction with mechanical systems
• Familiarity: with aerospace standards and regulatory requirements (FAA, EASA, MIL-STD, DO-160)
