Reactor Operations Engineer

About the role

Radiant is developing portable nuclear microreactors and seeks a Reactor Operations Engineer to design and implement mission‑critical procedures for reactor operators. This position bridges engineering, operations, and human‑factors to ensure safe, compliant execution of test, commissioning, and operational activities.

Key responsibilities

• Qualify as a reactor operator to gain hands‑on experience and validate procedures.
• Collaborate with engineers to improve operator interfaces, procedural workflows, and software tools.
• Support testing and iterative improvement of digital‑twin scenarios, operator systems, and human‑machine interfaces.
• Maintain compliance with DOE and NRC standards, ensuring procedural documentation is clear, correctly formatted, and usable.
• Develop and refine operational procedures that integrate software and hardware‑in‑the‑loop testing.

Required profile

• 4+ years of full‑time professional experience in engineering problem‑solving, including system design, analysis, or testing.
• Proficiency in managing or optimizing complex hardware and software processes for testing and operations.
• Ability to apply first‑principles thinking to solve problems in uncertain or ambiguous situations.
• Background in highly regulated industries such as nuclear, aerospace, aviation, or maritime.

Required skills

• Experience with complex hardware and software process optimization.
• Knowledge of DOE and NRC regulatory requirements for procedural documentation.
