• Develop equipment solutions that enable new manufacturing process capabilities
• Lead structured technical reviews and stage-gate activities
• Develop equipment architectures supporting automation, reliability, maintainability, and facility expansion
• Apply thermodynamics, fluid mechanics, dynamics, controls, materials, and machine design principles
• Establish engineering standards for CAD, documentation, equipment design, and commissioning
• Support equipment build, integration, validation, and production deployment
• Develop technical documentation, design records, and review packages
• Support expansion of mechanical engineering and equipment development capabilities

Requirements

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a closely related field
• 5+ years of experience designing and building complex equipment or vehicle systems
• Advanced CAD experience
• Strong knowledge of GD&T

• Knowledge of mechanics, dynamics, and machine design
• Knowledge of control systems and basic programming
• Knowledge of materials science, including metals, polymers, and ceramics
• Knowledge of fracture mechanics, surface engineering, and wetting
• Experience developing linked system requirements and managing technical interfaces

Preferred Skills

• Experience developing first-of-kind manufacturing equipment
• Experience making build-versus-buy decisions for equipment and subsystems
• Experience developing equipment architectures for automation and scale-up
• Experience supporting prototype, test, validation, and commissioning activities
• Experience with equipment reliability and maintainability design
• Experience establishing CAD standards, engineering documentation practices, and equipment development processes
• Experience integrating mechanical systems with controls, automation, and process equipment
