Simulator Design Engineer III
Holtec International, Camden, NJ, United States
Simulator Design Engineer III
Holtec International and its subsidiary companies are developing the SMR‑300, a small modular reactor designed to provide an unfailingly safe and secure source of clean energy through nuclear fission. This position is offered by SMR LLC, a member of the Holtec International family—a global turnkey supplier of equipment and systems serving the nuclear, solar, geothermal, and fossil power generation sectors. Join a growing, multidisciplinary team of designers and engineers working on the next‑generation nuclear power plant. Holtec International is seeking applicants for the role of the Simulator Design Engineer III. This position is responsible for the development and maintenance of software used in the SMR‑300 simulator. The Engineer will apply industry best practices, regulatory guidance, codes and standards, and engineering expertise to support control strategy development and simulator‑assisted design activities. The Engineer will be part of a dynamic team executing a U.S. Government cost‑shared development program, requiring efficient completion of engineering assignments. The role involves working with advanced simulation tools, integrating system models, and ensuring simulator fidelity for operator training and engineering applications.
Locations: Camden, NJ; Covert, MI; or North Pittsburgh, PA.
Primary Responsibilities
Simulator Development & Maintenance:
Design, develop, and maintain high‑fidelity nuclear plant simulators, ensuring compliance with industry standards.
Implement control logic, thermal‑hydraulic models, and system responses for real‑time simulation.
Integrate RELAP5, S3R, and 3KeyMaster into simulation environments.
Ensure simulator configuration control and model validation.
System Modeling & Integration:
Develop and update thermo‑hydraulic, electrical, and mechanical system models to improve simulator accuracy.
Interface simulators with digital control platforms and plant control systems.
Support the integration of I/O systems for seamless data communication.
Testing, Validation & Troubleshooting:
Conduct verification and validation (V&V) testing to ensure simulation accuracy and compliance.
Diagnose and resolve software, model, and control logic discrepancies.
Perform regression testing to verify simulator performance after updates.
Collaboration & Technical Support:
Work with cross‑functional teams, including engineers and training personnel.
Support operator training programs by ensuring simulator responsiveness and reliability.
Requirements
Bachelor's degree in Mechanical, Electrical, or Nuclear Engineering, or a related field.
Experience with nuclear power plant systems and process modeling.
Strong proficiency in simulator tools, such as 3KeyMaster, RELAP5, MELCOR, or equivalent.
Understanding of plant control logic, I&C systems, and human‑system interface (HSI) concepts.
Eligible to work in accord with Department of Energy 10 CFR Part 810.
Preferred Qualifications
Experience with nuclear power plant systems and process modeling.
Experience in CFD modeling and multi‑physics simulation.
Ability to analyze plant operation data and translate it into simulation models.
Knowledge of digital twin technology and real‑time data integration.
Familiarity with NRC regulations and ANS‑3.5 standards for simulator certification.
Strong problem‑solving, troubleshooting, and analytical skills.
Compensation
Annual compensation based on skills and experience ranging from $145,000.00–$165,000.00.
Additional compensation earned through incentive structure.
Benefits
Medical, dental, and vision insurance.
401(k) retirement plan with company match.
