Protingent Staffing has an exciting direct hire Thermal Structural Engineer opportunity.

Job Responsibilities:

Perform thermal and structural analyses supporting the design and development of advanced microreactor systems.

Conduct heat transfer, thermal stress, fluid mechanics, and mechanical performance evaluations for reactorponents andplex systems.

Develop and execute engineering analyses using advanced simulation and FEA tools, with experience in ANSYS, COMSOL, Abaqus, or equivalent highly relevant.

Supportputational modeling, finite element analysis, and design optimization activities.

Evaluateponents and systems under steady-state, transient, and accident-condition operating scenarios.

Support mechanical design activities includingponent sizing, material selection, and design verification.

Take ownership of thermal and structural analysis activities, with opportunities for increased technical leadership based on experience level.

Prepare engineering calculations, technical reports, design documentation, and technical presentations.

Collaborate closely with nuclear, mechanical, materials, systems, and licensing teams.

Participate in design reviews, testing activities, and technical problem-solving efforts. engineering principles, ASME codes, and industry standards to support safe and reliable reactor designs.

More experienced engineers may take on expanded technical ownership, mentoring responsibilities, and leadership of analysis activities.
