Principal Mechanical Engineer

Role Overview:

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 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 Hawthorne CA.

Responsibilities:

• 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

Minimum Requirements:

• Bachelors degree in Mechanical Engineering or a related discipline
• 8 years of progressively responsible experience in platform-level mechanical design and system integration for aerospace and defense applications
• Proven experience integrating mechanical subsystems and mission systems into vehicles mobile platforms or fixed installations
• Strong proficiency with CAD tools (e.g. SolidWorks or equivalent) for large assemblies and top-down design
• Solid understanding of mechanical interfaces tolerancing alignment installation practices and interface control documents (ICDs)
• Familiarity with structural analysis methods (hand calculations FEA)
• Familiarity with ruggedized military hardware and environmental qualification considerations
• Experience interpreting and applying military standards such as MIL-STD-810 and related platform qualification requirements
• Demonstrated ability to lead technical decisions and resolve complex cross-disciplinary integration challenges
• Strong communication skills and ability to operate effectively in multi-project development environments
• Ability to obtain and maintain a U.S. security clearance

Preferred Requirements:

• Masters degree in Mechanical Engineering or a related field
• Prior experience serving as a mechanical technical authority on a program
• Experience with mechanisms and actuation systems including linkages bearings motors hydraulics and pneumatics gimbals or rotary joints
• 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)
