Job summary

Antares seeks a Responsible Engineer for Reactivity Controls – Mechanical in Torrance, CA to lead design, development, testing, and validation of mechanical systems that govern reactor reactivity and ensure safe operation.

You will architect and build mechanisms interfacing with electrical and software subsystems, collaborating across disciplines to define system architecture, requirements, and documentation. The role targets precision control, robotics or electromechanical experience.

Qualifications

• Bachelor's degree in engineering.
• 5+ years of experience in full-cycle design engineering roles 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.
