Fusion, the nuclear reaction that powers the sun and the stars, is a promising long-term option for a sustainable, non-carbon emitting global energy supply.
The ITER Organization (IO), based in the southern France, welcomes best talents who can together prepare the way to this new energy in a truly multi-cultural work environment.
We offer challenging assignments in a wide range of areas and encourage applications from candidates will all levels of experience. Applications from under-represented ITER Members' nations and women candidates are strongly encouraged, as IO strongly believes that a diversified, equitable, and inclusive workplace is crucial in solving one of the most complex scientific and engineering projects in the world today.
As the IO attracts and retains people coming from a vast array of different backgrounds and cultures, discrimination and exclusion cannot be tolerated. The IO believes it is our diverse perspectives and background that gives unique strength and value to the ITER mission, regardless of race, member nation, gender, religion, status, sexual orientation, or disability - all are welcome and respected at ITER.
The IO is committed to fostering a fair and equitable environment across all areas of the project, including compensation and benefits.
ITER CARE Values (Collaboration / Accountability / Respect / Excellence):
We perform our work with care, we care for the well-being of colleagues, our families and ourselves, and we care about the health of the planet for generations to come. CARE drives our work and our behaviors at ITER.

Overview
Are you looking for an exciting opportunity at the heart of an ambitious fusion energy project? Join our Plant & Process Engineering Division (PPED) within the Engineering Service Department (ESD) as a Mechanical Engineer.
As a Mechanical Engineer, your goals will include:
Performing the entire engineering life cycle (specification, design, qualification, procurement, installation, integration, commissioning and maintenance) for the scope of activity. Providing engineering input and technical support for the scope of activity. Ensuring deliverables are produced according to project schedule and budget, within a quality-assured environment that requires rigor and a systematic way of working. Developing, under the leadership of your discipline manager, your skills and experience for the benefit of the Project.
The ESD provides the required skilled engineering resources or services, which are necessary for the successful completion of the ITER Project.
PPED provides technical support to the ITER project in the field of design and analysis, procurement and delivery along the full engineering lifecycles of plant systems. Being a member of the PPED, 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 & Responsibilities
Primary Responsibilities:
Contributes to the delivery of mechanical designs and supports engineering activities for the scope of activity (e.g. vacuum, cooling, buildings, remote handling, rotating machinery etc.). Performs mechanical analyses, in addition to thermal and structural analyses of piping systems and mechanical components to validate the design. Writes technical documentation as required for the procurement, fabrication, qualification and testing of the equipment, prepare relevant tenders, and updates documents as needed. Follows up on the design, manufacturing for the scope of activity including qualification tests and final acceptance tests (FATs). Collects and verifies input data for the design of the assigned scope and reviews the deliverables produced by external design contractors.
Additional Responsibilities:
Provides assistance to the Domestical Agencies, contractors and ITER groups to carry-out engineering, R&D, interface control and procurement work as required. Reviews detailed workshop drawings or any Installation Procedures, Inspection & Test Plans and the installation testing issued by the installation Contractor. Issues inspection and observation reports when and where required. Provides expert criteria for mechanical and structural discipline related problems and follows-up on the resolution of the field engineering changes and installation non-conformances.
Please note that job descriptions cannot be exhaustive, and the staff member may be required to undertake other duties, which are broadly in line with the above primary responsibilities.
This position is shift and/or on-call based, and crucial to maintaining continuous operations and ensuring the highest level of service for our stakeholders. This requires shift rotation and/or availability including day, evening, and night shifts, as well as weekends and holidays, depending upon project or team needs;
Experience & Competencies
Essential:
Proven experience in Mechanical Engineering and/or mechanical components in the field of nuclear installations, within complex international environments or projects. Rotating Machinery: Technical background in centrifugal pumps selection, design, manufacturing, operation and maintenance (including instrumentation and DCS/PLC aspects), Stress Analyses: Modeling the structure, analyzing its response to loads using various methods like finite element analysis, calculating stresses, evaluating against design criteria, and optimizing the design based on analysis results Mechanical Engineering: Specifying, designing, testing, installing and maintaining mechanical components, systems and interfaces. Manufacturing Follow up: Experience in the follow-up of manufacturing of mechanical parts, including working knowledge of mechanical manufacturing techniques including qualification of structures and components. Continuous Improvement: proposing changes to processes only when necessary and systems to enhance efficiency, quality, and productivity over time. Quality Management Systems (QMS): apply the applicable procedures related to your field of activity.
Desirable:
Knowledge of software for mechanical engineering (e.g. ANSYS, ABAQUS, CAESAR II, STAAD PRO or similar). Knowledge of software for process engineering (e.g. Fathom AFT, ECOSIM PRO, or similar). Piping and equipment supporting systems technologies, as well as fixation systems for nuclear plants. Organizational Savvy: maneuvering comfortably through complex policy, process, and people related organizational dynamics. Optimizes Work Processes: knowing or identifying the most effective and efficient processes to get things done, with a focus on continuous improvement.
Qualifications
Essential:
Masterโs degree or equivalent in Mechanical, Energetic or Nuclear Engineering field or other relevant discipline. The required education degree(s) may be substituted by extensive professional experience involving similar work responsibilities and/or additional training certificates in relevant domains.
