Senior Mechanical Engineer – High-Speed Rotating Equipment

The Senior Mechanical Engineer will lead the design and development of high-speed rotating equipment and motor-generator systems, focusing on rotor dynamics, bearings, seals, and overall machine architecture. The role spans the full product lifecycle from initial concept through production and involves hands‑on work in a highly technical environment. It offers the opportunity to serve as a key technical focal point and to grow into a design leadership role, working on advanced aerospace, defense, and industrial applications.

• Lead mechanical design efforts for high-speed rotating equipment and motor-generator systems from concept through production.
• Develop and refine overall machine architecture, including rotors, bearings, seals, and supporting mechanical systems.
• Perform detailed mechanical design using Solid Works, including 3D modeling, drawings, and documentation for complex components and assemblies.
• Design mechanical solutions for electronics packaging, including controllers and power electronics, with attention to thermal management, shock and vibration robustness, environmental sealing, and EMI-conscious design.
• Conduct structural and thermal analyses using finite element analysis (FEA) and hand calculations to validate designs and ensure performance, reliability, and safety.
• Apply rotor dynamics expertise to analyze and manage critical speeds, stability, and vibration behavior of high-speed rotating systems.
• Specify and integrate bearings, seals, and related hardware appropriate for high-speed, ruggedized aerospace and defense environments.
• Support new product development activities, including concept generation, design trade studies, prototyping, and design optimization.
• Create and interpret detailed engineering drawings with proper GD&T to ensure manufacturability and assembly accuracy.
• Collaborate closely with electrical, manufacturing, and test teams to ensure cohesive system integration and to resolve interdisciplinary design challenges.
• Work directly with the shop floor to support prototyping, troubleshooting, and validation testing of mechanical and electromechanical systems.
• Ensure designs meet applicable aerospace and defense environmental standards such as MIL-STD-810, DO-160, and MIL-STD-5400, as relevant to the application.
• Contribute to continuous improvement of design practices, tools, and processes within a practical, hands-on engineering culture.
• Take ownership of assigned designs and projects, driving them through multiple phases of development and supporting them into production.
• Provide technical guidance and act as a focal point for high-speed rotating equipment design, with potential to grow into a formal design leadership position.
