As a Process Engineer, Chemical your goals will include:

Performing, reviewing, overseeing and accepting the design, manufacturing, testing, installation and commissioning activities of selected Tritium Plant sub-systems of ITER.

Supporting process plant solution delivery to ensure they are comprehensive and that the defined requirements are achieved and clearly demonstrated.

Using engineering analysis to inform design decisions whilst ensuring work aligns with relevant codes and standards.

Producing high-quality engineering solutions across a broad range of process engineering topics over the lifecycle of the system.

Ensuring deliverables are produced according to project schedule and budget, within a quality-assured environment that requires rigor and a systematic way of working.

The ESD Department provides the required skilled engineering resources or services, which are necessary for the successful completion of the ITER Project.

PPED Division provides technical support to the ITER project in the field of Process Engineering. Being a member of the Plant & Process Engineering Division, you will have the opportunity to share and develop your expertise with other colleagues working in the same discipline on different ITER units.

Key Duties and Responsibilities

Primary Responsibilities:

Produces and monitors the Tritium Plant sub-systems designs including system design, component selection, analysis (e.g. transient) and layout.

Prepares and/or reviews design solutions and technical specifications for Tritium Plant sub-systems equipment, in accordance with the requirements and guidance.

Performs the functional analysis of the Tritium Plant sub-systems to check that the design fulfils the requirements of full plant lifecycle including testing, commissioning, operation, maintenance and decommissioning;

Prepares and maintains design documents, in addition to communicating them with relevant interfaces and technical units.

Follows-up and reviews the design, manufacturing, testing, installation and commissioning activities of Tritium Plant sub-systems components and systems, including those performed by contractors.
