Mechanical Design Engineer II

Antares • Los Angeles, CA

19h • $90,000 - $150,000 • Onsite

About The Position

As a Mechanical Design Engineer in our Electronic Hardware, you'll serve as the Responsible Engineer (RE) for the mechanical design and development of hardware supporting the reactor's electronic systems. This includes the design of enclosures, equipment racks, mounting hardware, cable management features, and structural supports for control system electronics and associated instrumentation. You'll work closely with electrical, controls, manufacturing, and test engineers to define system layouts, enclosure requirements, thermal and environmental considerations, and verification plans. The ideal candidate has experience designing and releasing electronic hardware assemblies for production, creating detailed mechanical drawings and documentation, and managing CAD models, bills of materials (BOMs), and engineering data within a Product Data Management (PDM) system.

Requirements

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Nuclear Engineering, or a related engineering discipline.
• 2+ years of professional experience designing and developing mechanical hardware for electronic systems, including enclosures, mounting hardware, racks, or structural support assemblies.
• Experience creating 3D CAD models, detailed engineering drawings, and bills of materials (BOMs) for production hardware.
• Demonstrated ability to perform engineering calculations to size and validate mechanical components and support structures.
• Familiarity with geometric dimensioning and tolerancing (GD&T) and standard manufacturing processes for fabricated and machined components.
• Experience managing engineering documentation, revisions, and product structures within a Product Data Management (PDM) or Product Lifecycle Management (PLM) system.
• Demonstrated ability to collaborate effectively with multidisciplinary engineering teams, including electrical, controls, manufacturing, and test engineers, while clearly communicating technical information to both technical and non-technical stakeholders.

Nice To Haves

• Master's degree in Mechanical Engineering, Aerospace Engineering, Nuclear Engineering, or a related engineering discipline.
• Experience designing electronic enclosures, equipment racks, mounting hardware, and structural support assemblies for demanding operating environments.
• Knowledge of electronic packaging principles, including thermal management, vibration isolation, EMI/EMC considerations, nuclear radiation shielding, cable management, and environmental sealing.
• Experience performing structural and thermal analysis using engineering tools such as ANSYS, Femap, COMSOL Multiphysics, or equivalent FEA software.
• Experience designing for manufacturing and assembly (DFMA), including sheet metal, machined, welded, and fabricated components.
• Experience managing CAD models, engineering drawings, and product structures within a Product Data Management (PDM) or Product Lifecycle Management (PLM) system.
• Experience in the nuclear, aerospace, defense, robotics, or other highly regulated or high-reliability industries.

Responsibilities

• Design and develop mechanical hardware for reactor electronic systems, including enclosures, equipment racks, mounting hardware, cable management, and structural support assemblies.
• Create and maintain 3D CAD models, manufacturing drawings, bills of materials (BOMs), and engineering documentation to support fabrication and product release.
• Perform engineering calculations and analyses to validate the structural, thermal, and environmental performance of mechanical hardware.
• Collaborate with electrical, controls, manufacturing, and test engineers to define mechanical interfaces, packaging layouts, and installation requirements.
• Support prototype fabrication, testing, design verification, supplier engagement, hardware deployment, and the resolution of manufacturing, assembly, and field issues.
• Maintain engineering configuration within the Product Data Management (PDM) system and participate in design reviews throughout the product development lifecycle.
