The role will consist of supporting all aspects of valve engineering activities related to the HPC Project within the Joint Design Office (JDO).

The Valve Engineer is responsible for:

• Undertaking technical clarifications of valve related deliverables required for construction, with support of the Back Office teams who carried out the initial design studies (EPR-E, EDVANCE, CNEPE and valve suppliers).
• Gathering and reviewing input data, analysing and updating design assumptions, technical specifications, equipment data sheets and associated documentation.
• Reviewing valve design documentation and ensuring compliance with applicable project requirements, nuclear codes and standards.
• Performing and supporting valve engineering assessments, including functional and operational reviews.
• Assessment of operational requirements.
• Review of valve qualification and environmental requirements.
• Identification and implementation of appropriate design modifications.
• Managing and closing valve-related technical queries and open points.
• Assessing and providing technical responses to issues arising during manufacturing, testing, installation, commissioning activities.
• Review and integrating valve related modifications requested by project stakeholders after JDO handover.
• Performing engineering assessments and hand calculations to evaluate the feasibility and impact of proposed modifications.
• Review and checking technical documentation produced by suppliers and external engineering subcontractors.
• Proposing technical improvements and optimisation for valve designs and associated documentation.
• Working closely with system engineers, layout engineers, CAD designers and other disciplines to support valve integration within plant design.
• Leading technical meetings.
• Managing interfaces with multiple stakeholders.
• Providing technical expertise on valve operation, maintainability, reliability and nuclear safety requirements.

The Valve Engineer will also be responsible for coordinating valve related activities within the JDO and acting as the entry point for valve queries originating from HPC site. In this capacity, the engineer will:

• Coordinate technical activities across all valve packages and systems.
• Ensure consistency of technical solutions between stakeholders.
• Monitor and support the resolution of valve related open points.
• Facilitate communication between design teams, suppliers, construction teams and the client.
• Support project delivery objectives by ensuring valve engineering activities are executed in line with project schedules and quality requirements.

• Degree in Mechanical Engineering, Nuclear Engineering, or a related Engineering or Science discipline.
• Experience in valve engineering, including specification, design, procurement, qualification, manufacturing, installation, commissioning or maintenance of industrial valves.
• Experience working on complex engineering projects within highly regulated industries such as Nuclear, Energy, Oil & Gas,…
