What You’ll Be Doing


As a Mechanical Engineer, specialising in Valve Engineering, you’ll support all valve engineering activities for the Hinkley Point C (HPC) Project within the Joint Design Office (JDO), ensuring designs are compliant, constructible, and fit for operation in a nuclear environment.


Key Responsibilities



  • Provide technical clarification on valve-related deliverables required for construction, working closely with Back Office design teams (EPR-E, EDVANCE, CNEPE and valve suppliers).

  • Gather, review and assess engineering inputs, design assumptions, technical specifications, equipment data sheets and supporting documentation.

  • Review valve design documentation to ensure compliance with project requirements, nuclear codes and applicable standards.

  • Carry out valve engineering assessments, including:

  • Functional and operational reviews

  • Assessment of operational requirements

  • Qualification and environmental requirement reviews

  • Identification and implementation of design modifications

  • Manage and close valve-related technical queries and open points.

  • Assess and provide technical responses to issues arising during manufacturing, testing, installation and commissioning activities.

  • Review and integrate valve design modifications requested by project stakeholders following JDO handover.

  • Perform engineering assessments and hand calculations to determine the feasibility and impact of proposed changes.

  • Review and verify technical documentation produced by suppliers and engineering subcontractors.

  • Identify opportunities to improve and optimise valve designs and associated documentation.

  • Collaborate closely with system engineers, layout engineers, CAD designers and multidisciplinary teams to support valve integration across plant systems.

  • Lead technical meetings and manage interfaces with a wide range of stakeholders.

  • Provide subject matter expertise on valve operation, maintainability, reliability and nuclear safety requirements.


Coordination Responsibilities



  • Acting as the primary point of contact for valve-related queries from the HPC site, you will:

  • Coordinate technical activities across multiple valve packages and systems.

  • Drive alignment and consistency of technical solutions between stakeholders.

  • Monitor, manage and support the resolution of valve-related open points.

  • Facilitate communication between design teams, suppliers, construction teams and the client.

  • Support project delivery by ensuring valve engineering activities are executed in line with project schedules, quality standards and delivery objectives.
