Senior Mechanical Engineer; Generation; Nuclear

WSP is growing its nuclear engineering capability to support the next generation of nuclear projects across the United States. We are seeking a Senior Mechanical Engineer (Generation) - Nuclear who can bring proven engineering judgment and practical delivery experience to complex nuclear assignments, from operating-plant modifications and life-extension work to new nuclear and advanced reactor programs. This role is suited to an engineer who has developed meaningful depth in one or more mechanical disciplines and can apply that expertise across multidisciplinary projects, working directly with clients, technology providers, suppliers, and project teams to turn technical requirements into safe, constructible, and executable solutions.

You will have the opportunity to take ownership of challenging engineering scopes, influence design decisions, and help strengthen WSP's growing nuclear engineering practice.

• Independently plan, execute, and deliver mechanical engineering assignments in accordance with applicable quality programs, codes, standards, regulatory requirements, budget, and schedule.

• Perform or lead mechanical engineering for operating nuclear facilities, plant upgrades and modifications, new nuclear projects, small modular reactors, and advanced-reactor assignments, based on the project requirements.

• Develop and review design criteria, design bases, system descriptions, calculations, specifications, datasheets, equipment requisitions, technical evaluations, design change packages, drawings, and engineering reports.

• Apply mechanical engineering principles to plant systems and equipment such as piping, pumps, valves, pressure vessels, heat exchangers, HVAC, fluid systems, material handling equipment, and reactor or balance-of-plant components.

• Perform engineering analyses appropriate to assigned work, which may include equipment sizing and selection, hydraulics, heat transfer, piping or pressure-boundary evaluations, operability reviews, condition assessments, and design-basis calculations.

• Evaluate design alternatives with consideration for safety, performance, constructability, reliability, maintainability, operability, life-cycle cost, and applicable nuclear quality and licensing requirements.

• Support the equipment and supplier lifecycle, including technical requisitions, bid evaluations, vendor document reviews, resolution of design deviations and nonconformances, fabrication or test support, and verification that supplied equipment meets design requirements.

• Support project execution from concept through detailed design, procurement, fabrication, construction, commissioning, plant modification, maintenance, or outage execution. Participate in site walkdowns, field verification, troubleshooting, and resolution of emergent technical issues when required.

• Coordinate requirements and interfaces across mechanical, process, civil/structural, electrical, instrumentation and controls, safety, construction, suppliers, reactor technology providers, and client teams. Support design reviews and resolution of technical interfaces.

• Prepare scope, schedule, level-of-effort estimates, assumptions, and technical inputs for project planning and proposals. Provide technical guidance and review to less-experienced engineers and designers, consistent with the candidate’s level of expertise.

• Bachelor's degree in mechanical engineering or a closely related engineering discipline from an accredited institution.

• Professional Engineer license in at least one U.S. jurisdiction.

• Minimum 10 years of relevant mechanical engineering experience, including minimum 7 years in nuclear power.

• Demonstrated experience in at least one nuclear mechanical area, such as plant…
