Contractor - Mechanical Engineer 4 (NSSS Vessels & Structures)
Quick Summary
Perform and document structural and stress analyses of pressure vessels and primary equipment supports in accordance with ASME Boiler and Pressure Vessel Code (BPVC) Section III.
As a Mechanical Engineer 4 specializing in Nuclear Steam Supply System (NSSS) vessels and structures, you will perform advanced design and stress analyses for pressure vessels and primary equipment supports used in modular advanced light water reactor systems. You will apply your expertise in finite element analysis and nuclear engineering standards to ensure component integrity, safety, and regulatory compliance. Working within a multidisciplinary engineering environment, you will evaluate pressure, mechanical, and thermal loads while optimizing component designs. You will also provide technical leadership, mentor fellow engineers, and help resolve complex engineering challenges. Your work will follow rigorous nuclear quality assurance requirements and applicable U.S. regulatory guidelines. This fully remote contract opportunity is expected to continue through 2027, offering experienced engineers the chance to contribute to technically demanding nuclear engineering projects.
As a senior technical contributor within the NSSS Component Engineering organization, you will lead component analysis activities, ensure compliance with applicable engineering codes, and support high-quality design decisions. Your responsibilities will include:
-
Perform and document structural and stress analyses of pressure vessels and primary equipment supports in accordance with ASME Boiler and Pressure Vessel Code (BPVC) Section III.
-
Evaluate components under pressure, mechanical, and thermal loading conditions, including primary stress, primary-plus-secondary stress intensity ranges, and fatigue.
-
Use ANSYS finite element analysis software and CAD tools to assess component performance, support engineering decisions, and optimize designs.
-
Interpret project scope, technical requirements, design specifications, and applicable industry standards and regulations.
-
Ensure engineering evaluations comply with relevant ASME Section III requirements, including Subsection NB and/or NF, as well as applicable regulatory guidelines.
-
Provide technical leadership and engineering oversight for the NSSS Component Analysis Group, taking responsibility for results and technical quality.
-
Mentor and guide less experienced engineers, support their professional development, and maintain relevant training and technical qualifications.
-
Collaborate with colleagues and multidisciplinary engineering teams to coordinate design activities, resolve technical issues, and ensure effective project execution.
-
Communicate complex technical findings clearly to management, senior stakeholders, and other engineering disciplines.
-
Apply nuclear quality assurance requirements, including ASME NQA-1, 10 CFR Part 50 Appendix B, and 10 CFR Part 21.
-
Manage project tasks, timelines, and competing priorities independently while maintaining accuracy, dependability, and a strong safety culture.
-
Adapt to evolving project needs and perform additional engineering duties as required.
