Responsibilities
Support development of plant site/layout and design of buildings/structures through final design and construction of the Xe-100 plant
Perform, manage, and oversee engineering and construction of the site and building structures for the Xe-100 project. This includes planning, monitoring, and directing of the complete engineering efforts through all development life cycles
Apply engineering principles, codes and standards and best practices to design the site, buildings and structures for hazards including seismic, flood and wind
Define, manage, and verify the requirements for the site, buildings and structures. Ensure the buildings and structures perform required functions throughout the plant life cycle. Ensure that the requirements in the full life cycle are timely addressed in the system design (e.g., constructability, testability, reliability, maintainability, safety, flexibility, interoperability, etc.)
Develop innovative concepts that can be implemented in a cost-effective and schedule-considerate manner while meeting the needs of customers
Develop and implement risk-informed performance-based (RIPB) design criteria. Assist other teams to perform risk and hazard assessments, such as probabilistic risk assessment (PRA), failure modes effects analysis (FMEA) and hazard and operability analysis (HAZOP)
Work with construction teams to evaluate constructability, sequencing, material take-off, cost estimate, schedule development, and modularization concepts for the Xe-100 plant
Identify, define, and manage interfaces with internal and external teams to advance the Xe-100 design
Ensure compliance with all applicable local, national, and international codes, regulations, and quality standards
