What you will do

• Own plant-level interface control and maintain Interface Control Documents across reactor systems, balance-of-plant, site, and transportation packages.
• Translate plant, functional, and regulatory requirements into system-level performance requirements with bidirectional traceability to component specifications.
• Lead cross-discipline design integration reviews covering piping, structures, electrical raceways, HVAC, I&C, and shielding.
• Act as technical authority for the master 3D plant model and PLM environment, including clash detection, model maturity gates, and configuration control.
• Prepare and defend integration-related licensing documentation, respond to regulatory requests for additional information, and evaluate design changes.
• Drive constructability, operability, maintenance access, ALARA, human factors, and design-margin control through construction and commissioning.

Requirements
