System One
Thermal Hydraulics Software Engineer (Nuclear Required)
System One, Bellevue, Washington, United States, 98008
System One is seeking a motivated Core Thermal Hydraulics Software Engineer for a 12-month contract to support the software development for the reactor core of the sodium-cooled Natrium Reactor program. Reporting to the Manager of Thermal Hydraulics for Core Design and Methods, you will advance thermal-hydraulics software for analyzing the behavior of advanced energy systems under various operating conditions.
The information below covers the role requirements, expected candidate experience, and accompanying qualifications.
Key Responsibilities:
Develop, test, and verify computational software to model and analyze core thermal hydraulics for the Natrium demonstration reactor.Collaborate with interdisciplinary software development teams, actively participating in all stages of the software development lifecycle, including integration into the software quality assurance (SQA) program.Work closely with QA teams to ensure that translated code meets required quality standards and acceptance criteria.Participate in code reviews, providing feedback to enhance code quality, maintainability, and validation traceability.Prepare reports and presentations to document findings, make recommendations, and communicate progress to core thermal hydraulics team managers and leads.
Qualifications and Skills:
B.S., M.S., or Ph.D. in Mechanical, Nuclear, Computer Science, or a related technical engineering field from an accredited university.A minimum of 5+ years of industry experience (nuclear or related) with a B.S. degree, or 3+ years with an M.S. or Ph.D., demonstrating expertise in software development and nuclear reactor core thermal-hydraulic analysis.Proficiency in Python programming and experience with Git or similar version control systems; preference for candidates also proficient in C++.Experience with Software Quality Assurance (SQA) programs and familiarity with Nuclear Quality Assurance (NQA-1) standards is highly preferred.Excellent verbal and written communication skills, essential for working within an NQA-1 environment and for formally documenting calculations.Experience with nuclear reactor subchannel or systems codes (e.g., RELAP5-3D, TRACE, COBRA, SLTHEN, SABRE4) is preferred.Knowledge of liquid metal thermal-hydraulics is a plus.Strong integrity, open communication, and the ability to work collaboratively within a team-focused environment.
This is an exciting opportunity to contribute to cutting-edge nuclear reactor technology and be part of a dynamic and collaborative team.
