The European Organisation for Astronomical Research in the Southern Hemisphere (ESO) is the foremost intergovernmental astronomy organisation in Europe and the world's most productive ground-based astronomical observatory. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries.


ESO operates three unique world-class observing sites in northern Chile: La Silla, Paranal and Chajnantor (home to ALMA and APEX), and the ESO Headquarters are located in Garching, near Munich, Germany.


At Paranal, ESO operates the Very Large Telescope, the world's most advanced visible-light astronomical observatory. ESO is a major partner in ALMA, the largest astronomical project in existence. And on Cerro Armazones, ESO is building the 39-metre Extremely Large Telescope (ELT), which will become "the world's biggest eye on the sky" and whose operations will be fully integrated into the Paranal Observatory.


For its Project Management Department (PMD) within the Directorate of Programmes, and in the frame of the on-going construction in Chile of the ELT Dome and Telescope (Dome & Main Structure (DMS)), ESO is opening the position of

ELT DMS Deputy Site Manager


Vacancy closed on 19/03/2019

Deadline 19/03/2019

The selected candidate will be assigned to the Dome and Main Structure (DMS) team in charge of the supervision of the contract for the design, fabrication, transport, erection, commissioning and testing of the protective enclosure ("Dome") and of the telescope structure ("Main Structure") of the ELT at the Armazones site in Chile.

Main Duties and Responsibilities:

The DMS Deputy Site Manager will contribute to the supervision on- site of the activities of the DMS contractor company awarded by ESO for the construction, erection, commissioning and testing of the ELT Dome and Main Structure. The DMS Contractor has erected a construction camp on site in 2017 with workshops, dormitories and logistical facilities. Construction of the DMS has started in 2018. Excavations have been completed and civil works are starting. The design in Europe is well advanced and production in Europe of parts of the DMS has been initiated. Erection on site is due to start toward the end of 2019 with the rotating enclosure (Dome) and later of the telescope structure (Main Structure). Delivery of the finished DMS is planned for 2024.

As Deputy DMS Site Manager, the selected candidate will have the following general responsibilities in monitoring the work of the DMS Contractor:

  • To interface with the DMS Contractor on-site tasked with the construction, erection, commissioning and testing of the ELT Dome and Main Structure, representing the ESO DMS Site Manager and ESO DMS Project Manager at the Armazones site.
  • To monitor the adherence by the DMS Contractor to the Statement of Work in force. The Statement of Work covers all civil works related to the buildings and plants under construction (Dome, Auxiliary Building, Chiller plant), as well as the erection and commissioning of the rotating part of the Dome (enclosure) and of the telescope (Main Structure).
  • To hold regular coordination meetings with the DMS Contractor with formal minutes and follow the agreed actions. Ensure that any agreement reached with the DMS Contractor receives the proper contractual follow-up and written endorsement by ESO Management and ESO Contract and Procurement Department, in accordance with the contractual rules.
  • To verify the correct application by the DMS Contractor of the ESO working procedures and regulations in force, with particular attention to safety regulations.
  • To control and record the works performed on-site by the DMS Contractor in terms of quality and planning. This includes the monitoring of the quality of the work execution and the collection of quality records, supported by other ESO key specialists and/or external Quality Assurance consultant(s).
  • To review, agree or ensure improvements on the completion of DMS Contractor works for specific progress milestones, if needed.
  • To perform, participate or organize formal Test Readiness Review associated with the acceptance testing of the DMS. Lead and coordinate the DMS verification and acceptance activities with the DMS Contractor based on an agreed verification plan.
  • To coordinate the works of other ESO Contractors and external visitors on-site, and ensure the avoidance of conflict, as well as the adherence to the Cerro Armazones access policy and the safety procedure in place. This includes visits requested by ESO, and access by ESO personnel and specialists in conjunction with the commissioning and testing of the DMS.

Additional tasks as part of the ELT team will be:

  • Report to and discuss with the ESO DMS Site Manager the course of actions and issues raised and escalate where appropriate to the ESO DMS Project Manager.
  • To participate, on demand, in the follow-up and the review of the design and manufacturing of the Dome and the Main Structure developed by the DMS Contractor, by taking part (videoconference or in person) in technical meetings and/or formal design reviews. This may include shipment and inspection points.
  • Plan, organise and coordinate the works of other ESO personnel acting on-site for the DMS contract (civil engineer, site safety, erection engineer, electric engineer, testing and commissioning specialists and consultants).
  • Participate in and report at regular DMS coordination meetings.
