Provide engineering oversight on plant mechanical systems including piping, pumps, heat exchangers, valves, HVAC, and other balance-of-plant equipment. Collaborate with project management, station engineering, procurement, and construction to ensure successful execution of projects. Coordinate engineering responses, resolve technical issues, and assess vendor submittals across all project phases—from scope development to implementation. Interface with internal stakeholders to ensure vendor alignment with plant configuration control, QA, and licensing requirements. Participate in technical discussions, root cause evaluations, and system health assessments. Ensure application of ASME codes, nuclear standards, and NRC regulations in all engineering reviews and decisions. Stay current on EPU-related technologies, trends, and performance implications to support plant modernization. Qualifications: Bachelor’s degree in Mechanical Engineering from an ABET-accredited program. Minimum of 7 years of progressively responsible commercial nuclear experience. Prior experience with Extended Power Uprate (EPU) projects is highly preferred. Demonstrated knowledge of mechanical systems in nuclear plants and familiarity with the applicable ASME codes, NRC regulations, and QA processes. Ability to critically evaluate engineering calculations and design packages prepared by external organizations. Strong communication skills with the ability to interface with vendors, contractors, project teams, and plant leadership. Experience in a leadership or oversight role, ideally representing plant owner interests. Professional Engineering (P.E.) License is preferred but not required. Ref: #161-Managed Staffing Charlotte
