The Mechanical Engineer (Ground Systems Equipment) will play a critical role in designing, developing, and optimizing packaging equipment for our missile systems. You will be responsible for creating robust, reliable, and efficient mechanical systems that ensure the safe transport, storage, and deployment of advanced defense technologies. This role demands technical excellence, creativity, and ownership, as you will work across the full design lifecycle to deliver mission‑critical solutions in a fast‑paced environment.

• Design, develop, and test ground equipment for missile systems, ensuring durability, reliability, and compliance with defense standards.
• Create detailed 3D models, engineering drawings, and specifications using CAD software (NX Preferred, other experience OK).
• Optimize designs for manufacturability, weight reduction, and environmental resilience, including shock, vibration, and thermal considerations.
• Collaborate with electrical engineers, software engineers, and manufacturing to ensure seamless integration of packaging equipment with missile systems.
• Perform structural, thermal, and dynamic analyses to validate designs under various operational and environmental conditions.
• Develop prototypes, conduct testing, and iterate designs to meet performance, reliability, and safety requirements.
• Troubleshoot and resolve mechanical design issues and see solutions through.
• Identify opportunities for innovation proposing designs that enhance system efficiency, modularity, cost, and scalability. Knowledge of existing commercial systems is a plus.
• Contribute to process development, effectively communicating technical challenges, risks, and solutions to cross‑functional teams.

• Proficiency in CAD software (e.g., NX, CATIA, or equivalent) for designing complex mechanical systems.
• Experience designing mechanical systems or equipment for high‑reliability applications, with a focus on structural integrity and environmental resilience.
• Strong understanding of mechanical engineering principles, including statics, dynamics, materials science, and thermal management.
• Ability to execute in a fast‑paced, high‑iteration environment, delivering designs that meet tight timelines.
• Familiarity with the full design lifecycle, from concept and prototyping to testing, manufacturing, and deployment.
• Demonstrated extreme ownership and ability to drive projects to completion with minimal oversight.
• Experience with finite element analysis (FEA) and computational tools is a plus but absolutely must know how to do hand calculations and free body diagrams.
• Ability to work on‑site in Huntington Beach, CA.

• Significant experience designing reliable and robust ground equipment for defense, motor sport, and/or film industries.
• Expertise in designing for extreme environments, including shock, vibration, and temperature extremes.
• Hands‑on experience with prototyping, testing, and validation of mechanical systems using tools like CNC machines, 3D printers, or environmental test chambers.
• Familiarity with defense industry standards (e.g., MIL‑STD‑810) for environmental and operational testing.
• Experience with materials selection for lightweight, high‑strength applications, including composites and advanced alloys.
• Strong understanding of human factors and what leads to design that prevent errors.
• Knowledge of robotics and UAVS.
• Strong feel for and interest in…
