Mechanical Design Engineer II - Reactivity Controls

The role

You will lead the design, development, testing, and validation of mechanical systems that govern reactor reactivity. You will architect mechanical mechanisms that interface with electrical and software subsystems.

What you will do

• 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.

Required qualifications

• Bachelor's degree in engineering
• 3+ years of experience in a full-cycle design engineering roles, encompassing hands-on 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
• Ability to work long hours and weekends as necessary to support critical milestones

Nice to have

• Master's degree in engineering
• 1+ years of experience in a full-cycle design engineering roles, encompassing hands-on experience with CAD, analysis, build and test
• Experience in the Nuclear, Aerospace, or Robotics industries
• Experience in a demanding fast-paced development environment
• Experience with design engineering tools such as NX, ANSYS or Femap, and other product lifecycle software
• Experience with engineering scripting languages such as Python and MATLAB
