The Very Large Telescope Interferometer (VLTI) is an ESO flagship infrastructure and facility combining the light from the four 8.2-meter Unit Telescopes and the four associated movable Auxiliary Telescopes. Its development recently included the GRAVITY and MATISSE instruments, and the planned final commissioning phases of GRAVITY+ will mark a milestone for its scientific performance and capabilities.

ESO is inviting applications from motivated and visionary scientists for the position of VLTI Project Scientist. We are especially keen to welcome applicants who bring a collaborative spirit and a passion for advancing science and technology at the highest level with expertise in instrumentation for optical/infrared interferometry or related fields. The ESO VLTI Project Scientist will support instrumentation developments in the Instrumentation Programme (in particular GRAVITY+), as well as activities within ESO's Technology and Developments programme.

This Project Scientist will interface with groups at external institutes or consortia working on developments or upgrades. This position provides a unique opportunity to play a key role in advancing a world-class astronomical facility while working at the heart of a vibrant, cross-disciplinary team. You will join ESO's supportive and globally connected research environment, where collaboration and innovation are deeply valued.

You will have the freedom to drive forward your own scientific research, benefit from robust professional development opportunities, and contribute to cutting-edge developments in optical/infrared astronomy. ESO fosters a workplace culture rooted in inclusion, fairness, and scientific excellence.
