• Regularly interface and communicate component requirements with other disciplinary teams including nuclear design, reactor systems, reactor coolant auxiliary systems, safety analysis, remote handling, and manufacturing.
• Maintain knowledge of and assess compliance with applicable codes and standards such as ASME, ANSI, ASTM, and others.
• Engage with manufacturing, assembly, and operations teams to support build, install, and maintenance operations.
• Perform design verification and validation activities to ensure system performance meets functional and safety requirements.
• Participate in hazard and failure analyses (HAZOP, FMEA, FTA) and incorporate safety insights into design iterations.
• Contribute to configuration management by maintaining design baselines, revision control, and traceability of changes.
• Assist in cost, schedule, and risk assessments related to mechanical design and plant layout activities.
• Participate in peer design reviews and technical audits to ensure compliance with quality and performance objectives.
• Other duties as assigned.

Requirements

• Bachelor’s or advanced degree in Mechanical, Nuclear, or Systems Engineering (or related discipline).
• 10+ years of experience in nuclear plant design, system integration or complex facility layout.
• Proven ability to lead cross-disciplinary integration and resolve technical and spatial conflicts.
• Demonstrated experience in system integration, equipment layout and standardization, and 3D CAD model management.
• Experience in reactor component fabrication and life cycle management processes including equipment qualification, in-service inspection, and other programs.
• Experience with configuration management systems or PLM tools.
• Experience with prototype or test rig development for mechanical systems.
• Experience working to a quality standard, such as ASME NQA-1 or ISO 9001.
