As part of the Extremely Large Telescope (ELT) development, the activities for the Assembly, Integration and Verification phase (AIV) involve the installation, integration and verification of the telescope's systems and components. These activities require close coordination between engineering teams, technical specialists and support services working at Cerro Armazones and Paranal Observatory.

The selected candidate will be part of the AIV On Site Engineering Department (OED), which provides the main engineering workforce that will integrate the ELT including: installation and alignment of the mirrors and optical sensing subsystems; deployment of supporting infrastructure; control system installation and commissioning; telescope commissioning. The AIV technician will provide hands-on technical and logistical support for the preparation and execution of these activities on-site.

The successful candidate will help ensure that work areas, equipment, tools and infrastructure are ready for technical operations, while providing practical support to project teams during installation and integration activities. This includes preparing the working areas, checking the availability of equipment and infrastructure, organizing tools and consumables, supporting small procurements, checking the readiness of the facilities and providing local technical support to the teams arriving from Europe.



Local support is also needed during the activities to solve practical issues and coordinate with the different technical teams on site.

Main Duties and Responsibilities:

- Preparation of work areas prior to AIV activities.
- Mechanical and electrical support for installation and integration activities.
- Coordination of local logistical preparations with site services and other ESO departments and project teams.
- Support for minor procurements, material reception and organization of tools and consumables.
- Verification of infrastructure readiness before the arrival of project teams.
- Day-to-day technical support for visiting project teams during mobilization and demobilization.

The successful candidate must have a professional qualification in Engineering Technology or Applied Engineering (Ingeniería en ejecución) in Mechanical, Electrical, Electromechanical, Industrial or a related technical field, or an equivalent technical or engineering qualification from a recognised higher education institution. This is a project related position offered on an initial two-year fixed term contract, subject to medical clearance and successful completion of the probation period. The title or grade may be subject to change according to qualification and the number of years of experience.

Deadline for applications is 25 November 2026.
