Antares; Torrance, Northern (CA, KY); Hybrid; USD 145,000 - 185,000; Full time

Job summary

Antares in Torrance, CA, is seeking a Senior Mechanical Design Engineer to lead the design, development, and validation of mechanical systems that govern reactor reactivity. You will interface with electrical and software subsystems, defining architecture, requirements, and documentation.

The ideal candidate has a track record in precision control mechanisms, with robotics or electromechanical systems experience, and will support vendor evaluation and system-level trade studies.

Qualifications

• Bachelor's degree in engineering is required.
• 5+ years of full-cycle design engineering experience with CAD, analysis, build and test.
• Experience with kinematic synthesis, pneumatic/hydraulic actuation, mechatronics and instrumentation.
• Experience with FMEA including structure strength, stability, and fatigue failure modes.

Responsibilities

• Design, build, and test the reactor’s control mechanisms, hardware, and assemblies.
• Concept and develop custom actuation solutions, including mechanisms, linkages, interfaces, and instrumentation.
• Define design criteria, requirements, system architecture, and verification/validation test plans.
• Collaborate closely with cross-functional teams across thermal, structural, neutronics, controls, and simulation disciplines.
• Engineer components for high-temperature, high-stress, and radiation environments using metals, ceramics, and other advanced materials.
• Perform design-for-manufacturability (DFM) assessments and execute tradeoffs across performance, cost, schedule, and risk.
• Conduct mechanism trade studies, document findings, and present recommendations to senior leadership.
