Job Description
Job Posting Organization:
The ITER Organization (IO) is a pioneering international project aimed at demonstrating the feasibility of nuclear fusion as a large-scale and carbon-free source of energy. Established to advance the development of fusion energy, the organization operates in a multi-cultural environment and encourages diversity among its workforce. The ITER project is a collaborative effort involving multiple countries, and the organization is committed to fostering an inclusive workplace that values different perspectives and backgrounds. The ITER Organization is dedicated to creating a fair and equitable environment across all areas of the project, including compensation and benefits, and actively promotes applications from under-represented nations and women candidates.

Job Overview:
The position of Systems Engineer, Functional Integration is situated within the Engineering Services Department (ESD) of the ITER Organization. This role is crucial for ensuring the functional integration of various systems throughout their lifecycle, which includes managing technical requirements and ensuring that deliverables are produced according to project schedules and budgets. The Systems Engineer will work closely with discipline managers to develop their skills and contribute to the overall success of the ITER project. The role requires a systematic approach to work, ensuring compliance with design standards and project requirements while fostering collaboration among team members. The Systems Engineer will also be involved in the validation of requirements during the commissioning phase, ensuring that all systems meet the specified requirements throughout their lifecycle.

Duties and Responsibilities:
The primary responsibilities of the Systems Engineer include managing the functional integration of one or several systems across the entire lifecycle, authoring and reviewing requirements documentation, and ensuring that the system design fulfills all technical requirements. The engineer will perform configuration management tasks, including the technical assessment of Project Change Requests (PCRs), Design Reviews (DRs), and Non-Conformance Reports (NCRs). Additionally, the engineer will identify and resolve transverse technical issues and functional integration challenges, ensuring compliance with design standards and project requirements. The role also involves partnering with technical units to prepare design gate reviews, managing the optimization of design requirements, and providing expert criteria for functional integration-related problems. The position may require shift work and on-call availability to maintain continuous operations and ensure high service levels for stakeholders.

Required Qualifications:
Candidates must possess proven experience in the design and functional integration of nuclear systems within large international nuclear projects. Essential qualifications include expertise in Systems Engineering and Functional Integration, nuclear engineering principles, problem-solving skills, technical resolution capabilities, and knowledge of industry codes and standards. Continuous improvement and quality management systems experience are also essential. Desirable qualifications include familiarity with requirements management software and plant life cycle management, as well as skills in reporting, follow-up, and management of actions. Organizational savvy and the ability to optimize work processes are also beneficial.

Educational Background:
A Master’s degree or equivalent in Mechanical, Process, or Nuclear Engineering, or a related discipline is required for this position. Additional certifications such as INCOSE certification, PMP certification, or similar qualifications are desirable. The required educational background may be substituted by extensive professional experience involving similar work responsibilities and/or additional training certificates in relevant domains.

Experience:
Candidates should have a significant level of experience in nuclear engineering, particularly in the context of large international projects. This includes experience in defining, implementing, and managing end-to-end systems and their functional integration, as well as ensuring compliance with specified requirements throughout the system's lifecycle. Experience in problem-solving, technical coordination, and applying industry standards is essential for this role.

Languages:
Fluency in English, both written and spoken, is mandatory for this position. Proficiency in additional languages may be considered an asset but is not required.

Additional Notes:
The position offers an initial employment contract of up to five years, with the possibility of extension. The entry grade for this position begins at P1, and the final grade offered to the selected candidate will be determined by the IO Director General. The selection process aims to fill the current vacancy and create a reserve list of candidates for future positions. The reserve list will initially remain valid for two years, with the possibility of extension at the Director-General's discretion. The role may require shift work and on-call availability, including nights, weekends, and public holidays, depending on project needs. A valid driving license in France is required for staff expected to perform on-call or shift work.
