Principal Mechanical Engineer

Responsibilities:

• Own mechanical architecture and integration of launcher systems across multiple platforms (ground and maritime)
• Define and manage mechanical and electro-mechanical interfaces between missile, canister, and platform
• Develop solutions for environmental protection and blast, plume, and thermal effects including gas management, shielding, and structural protection
• Ensure compliance with safety interlock requirements and launch sequencing constraints.
• Design mechanical safing features and contribute to system-level hazard analyses.
• Design and develop mechanisms and actuation systems for deployment, retention, and release
• Ensure compliance with relevant military standards
• Serve as a primary technical hardware interface with customers, platform providers, suppliers, and manufacturing partners. Perform make/buy assessments
• Lead integration of launcher systems onto mobile ground and maritime platforms, accounting for structural loads, motion environments, corrosion, and installation constraints
• Support production transition, configuration control, and fielded system sustainment, including investigation and resolution of integration issues
• Minimum Requirements:
• Bachelor’s degree in Mechanical Engineering or a related discipline
• 10+ years of progressively responsible experience in mechanical design and system integration for aerospace or defense
• Demonstrated experience designing missile launcher systems or closely related hardware
• Strong background in structural design, mechanisms, and ruggedized hardware for harsh environments
• Experience with electro-mechanical integration, including power and data interfaces and connector systems
• Working knowledge of blast, thermal, and dynamic loads associated with rocket or missile systems
• Familiarity with system safety principles, including safe-and-arm or fuzing interfaces and launch interlocks
• Strong proficiency with CAD tools (e.g., SolidWorks or equivalent) and experience designing large assemblies
• Solid understanding of mechanical interfaces, tolerancing, alignment, installation practices, and interface control documents (ICDs)
• Experience interpreting and applying military standards (e.g., MIL-STD-810) and environmental qualification practices
• Demonstrated ability to lead technical decisions and resolve cross-disciplinary integration challenges
• Strong communication skills and ability to operate across multiple programs
• Ability to obtain and maintain a U.S. security clearance
• Preferred Requirements:
• Master’s degree in Mechanical Engineering or a related field
• Prior experience serving as a mechanical technical authority on a program
• Experience planning, instrumenting, and executing hardware tests
• Experience with designing and integrating mechanisms and actuation systems
• Experience with system-level requirements allocation
• Familiarity with vehicle integration constraints, including shock, vibration, transport, and operational loads
• Experience with at least one commercial FEA or multiphysics simulation package (NASTRAN, ABAQUS, ANSYS, CFD codes, COMSOL, etc.)
• Knowledge of manufacturing and assembly processes for mobile or deployable mechanical structures and mechanisms
• Experience with prototyping, additive manufacturing, CNC machining, and other fabrication techniques
• Familiarity with military-style connectors (e.g., mil-circular 38999, ARINC, micro-D)
