Simulator Engineer

Position Title: Simulator EngineerPosition Description: Protingent Staffing has an exciting FTE Simulator Engineer opportunity.Job Responsibilities:

• Develop, maintain, and enhance dynamic models of reactor systems, including primary sodium coolant loops, intermediate circuits, decay heat removal systems, and associated instrumentation & control (I&C) logic using FORTRAN, C++, and Python.
• Configure, maintain, and troubleshoot real-time simulation platforms (R*Time and RTP), and support integration with control room hardware, digital I&C, and interface systems.
• Employ 33 Key Master tools for model version control, configuration management, performance benchmarking, and change tracking.
• Collaborate with reactor design engineers, I&C engineers, training specialists, and human factors experts to ensure simulator fidelity across normal operations, transients, and off-normal conditions.
• Participate in simulator upgrade or replacement projects, including rehosting, model enhancements, digital I&C adaptation, and improved visualization.
• Perform acceptance testing, validation, debugging, and model verification to ensure simulator behavior aligns with plant calculations, design basis events, and training needs.
• Support training sessions by diagnosing simulator issues, implementing corrective model actions, and minimizing downtime during training.
• Produce and maintain detailed engineering documentation, model descriptions, test records, and change logs in compliance with nuclear quality assurance (QA) standards and configuration control processes.
• Align simulator development with applicable standards such as ANSI/ANS-3.5, NRC licensing requirements (10 CFR 55), and INPO accreditation.

Job Qualifications:

• Bachelor’s degree in Nuclear Engineering, Mechanical Engineering, Electrical Engineering, Computer Science, or related technical discipline OR relevant work experience
• Minimum 3–5 years of experience in training simulator engineering, real-time simulation, or plant system modeling—preferably in a nuclear or heavily regulated environment.
• Proficiency in FORTRAN, C++, and Python programming languages.
• Experience working with real-time simulation platforms (R*Time and/or RTP).
• Familiarity with 3 Key Master or equivalent configuration management/version control environments.
• Strong analytical, debugging, and problem-solving skills.
• Excellent communication and documentation skills.
• Travel Required: 0-10%

Preferred Skills:

• Direct experience supporting nuclear simulator development for advanced reactor technologies (fast reactors, sodium-cooled systems) or first-of-a-kind plants.
• Understanding of fast reactor physics, liquid-metal thermal/hydraulics, sodium coolant system behavior, or similar advanced reactor technologies.
• Knowledge of ANSI/ANS-3.5 simulator standards, NRC licensing processes (10 CFR 50/52), INPO simulator accreditation, or nuclear QA (NQA-1)
• Experience in the training organization of a nuclear power plant or working with digital I&C integration, human-system interface (HSI) validation, or plant commissioning.

Key Competencies:

• High technical aptitude and adaptability, especially in emerging nuclear technologies.
• Demonstrated commitment to safety, quality, and regulatory compliance.
• Strong collaboration skills—able to work effectively with instructors, engineers, designers, and training staff.
• Ability to manage multiple tasks and priorities under tight timelines in a fast-paced environment.
• Self-driven learner with strong initiative for technical improvement and innovation.
• Clear and effective verbal and written communication, capable of articulating complex technical topics to diverse audiences. #TerraPro
