Desirable

• CHAOS is seeking a Principal Mechanical Engineer to provide high-value, hands-on mechanical expertise for the integration of ruggedized electronics, effectors, and mission-critical hardware into ground- and sea-mobile platforms for aerospace and defense applications
• In this role, you will own and lead the design for mechanical integration of military electronics and effector systems with critical platform structures and mechanisms. Design challenges may range from compact electronics enclosures to larger structural or mechanism assemblies, depending on platform and mission requirements
• The position spans the full product lifecycle, from early concept development and architecture through detailed design, analysis, prototyping, qualification testing, production, and sustainment of fielded systems
• The ideal candidate has strong hands-on mechanical CAD and system integration experience, demonstrated prototyping skills, a deep understanding of ruggedized hardware design, and a proven ability to work independently and guide cross-disciplinary engineering efforts
• This is a full-time, on-site position in El Segundo, CA
• Provide technical leadership and hands-on prototyping and mechanical integration of mission systems: electronics, enclosures, effectors, launchers, mechanisms, and support equipment into ground- and sea-mobile platforms
• Architect and design mechanical structures, frames, mounts, enclosures, and mechanisms subject to shock, vibration, thermal, and environmental constraints
• Develop and maintain 3D CAD models, assemblies, and interface control documentation (ICDs) to support multi-disciplinary system integration
• Perform first-order structural and thermal analyses and requirements allocations to ensure compliance with customer requirements and applicable military standards
• Lead system-level integration, qualification, and acceptance activities, including oversight of installation, alignment, and fit-check efforts
• Serve as a primary technical hardware interface with customers, platform providers, suppliers, and manufacturing partners. Perform make/buy assessments
• Support production transition, configuration control, and fielded system sustainment, including investigation and resolution of integration issues
