Job Description

As a Project Coordination Officer (HI-ECN3), you will be responsible for the planning and coordination of dismantling/installation activities associated to the HI-ECN3 project.

The HI-ECN3 project has the mission to create a new High-Intensity facility that will be located in the ECN3 existing cavern in order to exploit fully the SPS complex availability into a new intensity frontier for Fixed Target physics in Run4 and beyond.

With this in mind, and given that the HI-ECN3 project is already underway, a detailed coordination and planning (short, medium and long-term) is required in order to fit all the dismantling and installation activities within the time and resources available.

You will have the opportunity to integrate a dynamic team in charge of the Injectors programmed stops, with a large view of CERN infrastructures. This position allows learning and understanding the general organisation of CERN accelerators during a Long Shutdown, to support major projects, but also the opportunity to learn about CERN infrastructures. You will also have the opportunity to work with project management tools like MS Project and other planning tools, and increase your technical and behavioral skills in an international environment.

Your responsibilities:

You will join the HI-ECN3 project coordination team and you will contribute to:

• A continuous and smooth communication with the different work package leaders, works and service supervisors, and on-site teams.
• The dismantling/installation preparation process, to evaluate the work progress and detect deviations with respect to the defined planning, integration and functional aspects.
• The understanding of needs towards converting an existing infrastructure in a new experimental area.
• The control of documentation (e.g. technical specifications, Engineering Change Requests, Space reservations) and to the integration checks from the coordination point of view.
• The written reports or presentations, especially for the Technical Design Report document.

In collaboration with the different stakeholders, you will:

• Plan and coordinate dismantling and installation activities that will take place during the Long Shutdown 3, ensuring all activities are carried out within agreed overall schedule and space bounderies.
• Prepare all supporting documentation and liaise between the stakeholders.
• Identify and resolve conflicting co-activity issues with the stakeholders concerned and the Project Leader.
• Collect and structure information, perform analysis of the data collected and ensure a proper follow-up with the different stakeholders.
• Work in close collaboration with different work package leaders, works and services supervisor, to ensure their follow up and implementation.

Your profile:

• Good understanding of interactions between different engineering domains.
• Demonstrated capability of dealing with unstructured information and changes along the path.
• Project management and coordination (university project, previous work).
• Working with project planning tools (MS project or similar).
• Organisation, planning and control processes.

Skills:

• Structured thinking, organised and able to work independently.
• Efficient communication.
• Organisation, planning and control processes.
• Spoken and written English or French, with a commitment to learn the basics of the other language.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• By the application deadline, you have a maximum of two years of professional experience since graduation in Engineering (mechanical/electrical/industrial/aerospace) or a related field, and your highest educational qualification is either a Bachelor's or Master's degree.
• You have never had a CERN fellow or graduate contract before.
• Applicants without University degree are not eligible.
• Applicants with a PhD are not eligible.
