Register interest in developing the next giant telescope ELT

The European Southern Observatory (ESO) is building the world’s largest optical telescope, ELT, in the Chilean desert. Right now, ESO is seeking a number of persons to work on the development of the telescope.

The Extremely Large Telescope (ELT) will make it possible for researchers to study the universe in greater detail than ever before. The construction of ELT has already begun on the Cerro Armazones mountain in Chile, at a hight of just over 3 000 metres above sea level.

The Swedish Research Council and Big Science Sweden are now seeking one or two persons from Sweden to take part in completing ELT. The assignment is for 2–4 years at ESO, either in Garching outside Munich in Germany, or in Chile.

Your registration of interest should be sent to the Swedish Research Council

Please register your interest no later than 29 August 2022 via email to

The registration shall consist of a CV with information relevant to the position in question, and a brief justification. We will place great weight on long-term collaboration between ESO and Sweden. The registration may be written in Swedish or English.

What happens next?

The registrations of interest will be received by the Swedish Research Council and Big Science Sweden (BISS). Sweden is one of 16 member countries of the European Southern Observatory (ESO) that are contributing to the construction of the giant telescope ELT. Big Science Sweden (BISS) is a Swedish industrial liaison office for bodies such as ESO.

Feedback on who is eligible to submit a full application will be given no later than 9 September.

The candidates assessed as fulfilling the criteria will be asked to submit a full application in English by the end of September (exact date will follow). ESO will be arranging a digital information meeting for interested candidates, and more information will be available in August.

The candidates selected by ESO will retain their employments in Sweden, and be offered an “unpaid associate” position with ESO. The Swedish Research Council will pay for the salary during the period the person is working for ESO, and will in return receive a deduction from its membership fee. If the positions are not filled using this process, ESO will issue a call for them in the standard manner, when all persons in the member countries will be eligible to apply.
