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, and will host and operate the southern array of the Cherenkov Telescope Array, the world's largest and most sensitive high energy gamma-ray 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.
Due to the need for additional resources associated with its programmes, the Optical Engineering Department within the Directorate of Engineering at ESO Headquarters in Garching, near Munich, Germany is advertising the position of
We are looking for a photonics engineer/physicist to support ESO's laser guide star (LGS) activities, with a focus on: system testing, installation, and commissioning of the six laser guide star units for the ELT; supporting the ongoing operation of the laser guide stars at the VLT and upgrades for new instruments; participating in the development and on-sky testing of test benches for new laser guide star applications. Experience with laser optical systems (for example in the fields of remote sensing, laser communication, lithography, or astronomy) would be an advantage for this position. Applicants should have a good understanding of laser physics and be able to follow the latest developments in the field, applying them to LGS systems. This position provides the opportunity to work in a collaborative international environment and hands-on participation to large scale optical and photonic systems for astronomy.
The Optical Engineering Department comprises a team of 20 engineers. The department provides engineering expertise to ESO's projects within the ESO matrix organisation, in the areas of optical design for telescopes and instruments, active optics and wave front control, metrology for telescope alignment, laser guide stars, optical fibre technology and Assembly Integration and Testing of optical systems and instruments. In addition, the department manages 900m2 of optical and opto-mechanical integration laboratories at ESO headquarters and supports the observatory in solving optical problems arising in systems in operation. The laser and photonics group within the optics department has its roots in the development and deployment laser guide stars for ESO observatories. It also has capabilities in optical fibres and other laser applications for astronomical instrumentation.
Main Duties and Responsibilities
Participate in the assembly and system test of laser guide stars for ESO projects such as the ELT. Perform system and sub-system (laser source, projector, laser pointing camera, etc) tests, prepare test reports, and provide inputs to the compliance matrix.
Support the installation of the LGS on ESO telescopes in Chile. Participate in the commissioning and provide inputs to commissioning reports.
Support the ongoing operation of the LGS at the VLT and contribute to the design and specification of upgrades for new instruments. Examples of upgrades could include incremental performance improvements, complete additional LGS units, or overhauls.
Monitor new developments in lasers and optics relevant to laser guide stars; identify where they could be applied to ESO's LGS systems. Contribute to ESO's Technology Development programme and participate in R&D activities where new developments can be tested in the lab and on sky. Currently, the main experimental activity is a development called "CaNaPy".
You may be involved in scientific collaborations with European and non-European institutes. Extended missions to ESO's observatories in Chile may be required for the installation and commissioning of laser systems on ESO telescopes.
Head of the "Lasers and Photonics" group in the Optical Engineering Department as functional manager within ESO's matrix structure.

Candidates should have at least 3 years' experience designing, assembling, and testing laser optical systems (e.g. laser guide star, remote sensing/LIDAR, lithography, free-space communications).
Laboratory experience with high-power lasers and nonlinear frequency doubling would be an advantage.
Essential educational level: A university degree (master) in photonics engineering, physics, or a related technical field. A PhD degree or postgraduate experience in a relevant field would be an advantage.
The position requires a good working knowledge of English.
