Nuclear Systems Engineer - Reactor Operations

Nuclear Systems Engineer

We are seeking a Systems Engineer to design and implement mission-critical procedures for reactor operators managing our groundbreaking nuclear microreactor technology. This role offers a rare opportunity to bridge engineering, operations, and human factors in a highly technical and regulated environment. You will collaborate with a multidisciplinary team to translate complex hardware and software designs into clear, executable, and DOE or NRC compliant procedures. Your work will ensure that Reactor Operators (ROs) and Senior Reactor Operators (SROs) can efficiently and safely execute test, commissioning, and operational activities.

This position goes beyond traditional systems engineering—you will also gain hands-on experience as a reactor operator, directly influencing the development of operational software, procedures, and digital twin simulations. Your contributions will enhance operator efficiency, safety, and real-world execution of our cutting-edge microreactors.

Responsibilities and Duties:

• Develop and refine operational procedures that integrate both software and hardware-in-the-loop testing.
• Collaborate closely with engineers to improve operator interfaces, procedural workflows, and software tools.
• Qualify as an operator to gain firsthand experience, ensuring procedures align with real-world execution.
• Support testing and iterative improvements of digital twin scenarios, operator systems, and human-machine interfaces.
• Ensure compliance with DOE and NRC standards, maintaining strict formatting, clarity, and usability in procedural documentation.

Required Skills and Qualifications:

• Undergraduate degree in engineering discipline.
• 2+ 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 and make decisions in uncertain or ambiguous situations.

Desired Skills and Qualifications:

• Hands-on experience in developing technical procedures, human factors engineering, or operational interface design.
• Prior operations background such as mission control room operator. 
• Background in highly regulated industries (e.g., nuclear, aerospace, aviation, maritime).
• Proficiency in Python, UNIX, for procedure testing within the simulator environments.
• Experience with human factors and user-centered instructions for operational workflows.

Additional Requirements:

• Must be willing to work extended hours and weekends as necessary to achieve company goals.
• Must work 100% onsite at El Segundo HQ.
