Simulator Engineer

Position Title Simulator Engineer Position 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 Job Details Job Type: Direct Hire Salary Range: $141,385 - $212,079.
