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.

Are you looking for an exciting opportunity at the heart of an ambitious fusion energy project?

Join our Fusion Technology and I&C Division (FTIC) Division, within the Engineering Service Department (ESD) as a Systems Engineer, Functional Integration

As a Systems Engineer, Functional Integration, your goals will include:

• • • • Ensuring functional integration by managing technical requirements.
      • 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 Engineering Services Department (ESD) provides the required skilled engineering resources or services, which are necessary for the successful completion of the ITER Project.

FTIC Division provides technical support to the ITER project in the field of design, analysis, and lifecycle management of critical fusion and I&C systems.

Being a member of the FTIC Division, you will have the opportunity to share and develop your expertise with other colleagues working in the same discipline on different ITER units.

Primary Responsibilities

• Is responsible for the functional integration of one or several systems across the entire lifecycle.
• Authors and/or reviews requirements documentation and interface documentation.
• Ensures that the system’s design fulfills all technical requirements in the context of the global ITER environment.
• Performs configuration management tasksincluding the technical assessment of Project Change Requests (PCRs), Design Reviews (DRs), and Non-Conformance Reports (NCRs).
• Identifies and resolves transverse technical issues and functional integration challenges, ensuring compliance with design standards and project requirements.

Additional Responsibilities

• Partners with technical units in preparing design gate reviews to verify the functional integration of the system and the requirements implementation.
• Manages the optimization of design requirements and ensures that transverse requirements are well defined and implemented in the design.
• Supports the validation of requirements during commissioning according to the scope of activity’s final design phase.
• Provides expert criteria for functional integration-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;

Essential:

• Proven experience in design and functional integration of nuclear systems within a large international nuclear project.
• Systems Engineering and Functional Integration: defining, implementing, and managing an end-to-end system and its functional integration, and ensuring the system meets specified requirements throughout its lifecycle, managing associated risks and changes.
• Nuclear engineering; applying nuclear principles to engineering activities such as design, analysis, and operation of systems and processes.
• Problem Solving: assess problems, identify root causes, and propose solutions to reach project objectives within time and cost.
• Technical Resolution: Technical coordination of transverse technical topics to ensure global functional integration for the scope of activity.
• Codes and Standards: Understanding and applying industry, discipline or job-specific codes, standards, and regulations to ensure that products, services, and processes comply with applicable requirements and legal frameworks.
• Continuous Improvement: proposing changes to processes and systems to enhance efficiency, quality, and productivity over time.

Desirable:

• Software for requirements management software and/or plant life cycle management.
• Reporting, Follow-up, and Management of Actions: summarize and communicate in writing to a large audience on processes, procedures, reports, technical assessments, engineering documents, record, check and ensure implementation based on evidence.
• Scope Management: Defining, controlling, and managing the work scope of a project or activity, planning, measuring, and reporting on progress, including the identification and management of risks and changes.
• 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.

Essential:

• Master’s degree or equivalent in Mechanical, Process of Nuclear Engineering field or other relevant discipline.

Desirable:

• INCOSE certification, PMP certification, or similar.
• The required education degree(s) may be substituted by extensive professional experience involving similar work responsibilities and/or additional training certificates in relevant domains.
