Senior Mechanical Design Engineer

About the Role

As the Responsible Engineer for Reactivity Controls – Mechanical, you will lead
the design, development, testing, and validation of the mechanical systems that
govern reactor reactivity and ensure the safe operation of the reactor. You will
architect and build the mechanical mechanisms that interface with electrical and
software subsystems, collaborating closely across disciplines to define system
architecture, requirements, and documentation.

The ideal candidate has a strong track record in designing and developing
precision control mechanisms, preferably with experience in robotics or
electromechanical systems. You will also contribute to system-level architecture
trade studies and support the evaluation and selection of key vendors.

Roles and 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

Basic Qualifications:

Bachelor's degree in engineering

5+ years of experience in 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

Preferred Skills & Experience:

Master's degree in engineering

7+ years of experience in 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

Additional Requirements:

Ability to work long hours and weekends as necessary to support critical milestones
