Probabilistic Risk Assessment (PRA) Engineer – Entry Level (Contract)

Location: Remote
Pay Rate: $37-$74/hour
Position Type: Long-Term Contract

Position Overview

System One is seeking an Entry Level Probabilistic Risk Assessment (PRA) Engineer to support the development of next-generation advanced nuclear reactor technology. This role offers an excellent opportunity to work with a multidisciplinary engineering team performing probabilistic risk assessments, severe accident analysis, and safety evaluations that support reactor design, licensing, and regulatory compliance.

The selected candidate will contribute to the development and maintenance of PRA models, perform risk analyses, support hazard evaluations, and collaborate with engineering teams to ensure safe, reliable, and innovative reactor designs.

Responsibilities

• Support internal and external Probabilistic Risk Assessment (PRA) activities.
• Develop and maintain event trees, fault trees, and PRA models using CAFTA.
• Perform risk integration studies, importance measures, and risk metrics.
• Support severe accident and consequence analyses.
• Participate in hazard analyses, PIRT evaluations, SSC classifications, Licensing Basis Events (LBE), and Defense-in-Depth (DID) evaluations.
• Collaborate with multidisciplinary engineering teams to establish system reliability, safety, and performance requirements.
• Prepare engineering calculations, technical documentation, and analytical reports.
• Participate in design reviews and engineering evaluations.
• Present technical findings to project teams, management, and regulatory organizations.
• Support continuous improvement of PRA methodologies, computational models, and engineering processes.

Required Qualifications

• Bachelor's degree in Nuclear, Mechanical, Electrical, Aerospace Engineering, or related discipline.
• One or more years of Probabilistic Risk Assessment (PRA) experience.
• Understanding of PRA principles and familiarity with ASME/ANS PRA standards.
• Knowledge of risk-informed, performance-based regulatory approaches.
• Experience with PRA software such as CAFTA, FRANX, SAPHIRE, RiskSpectrum, or similar tools.
• Strong technical writing, analytical, and communication skills.
• Ability to work effectively on multidisciplinary engineering teams.

Preferred Qualifications

• Experience with GOTHIC, MELCOR, RADTRAD, or similar analytical software.
• Experience with sodium-cooled or advanced reactor technologies.
• Knowledge of severe accident analysis, human reliability analysis, source term evaluations, and accident progression.
• Familiarity with nuclear licensing and regulatory requirements.

This is an outstanding opportunity to contribute to the development of advanced nuclear technologies while working remotely on innovative, first-of-a-kind engineering projects.
