Job Announcement Text: 

Paranal Staff Astronomers play a key role to optimize the scientific return of the world leading astronomical facility.

In the last years, major new systems have complemented our suite of instruments. This includes the VLTI 2nd generation instruments Gravity & Matisse, the Adaptive Optics Facility (AOF) on UT4 and the exo-planet machine machine ESPRESSO. ERIS and the MOS facilities MOONS & 4MOST are upcoming systems at the VLT.

Furthermore, preparations for the full integration of the ELT into Paranal Science Operations have started.

The successful candidate will have the opportunity to gain and provide expert knowledge on novel instrumentation and will be given the overall responsibility for an instrument at the Very Large Telescope or future ELT. Flexibility exists so as to tailor duties and responsibilities according to personal expertise and interests.

Main Duties and Responsibilities:

The successful candidate will:

  • Contribute to the science operations activities for both visitor and service mode at Paranal Observatory. This includes planning and execution of observations, supporting visiting astronomers, and the calibration of instruments.
  • Provide quality assurance and quality control of the scientific data obtained.
  • Become instrument scientist for one of the current or future instruments at VLT and ELT. Activities include
    • improve operations and scientific performance
    • definition, implementation, optimization and characterization of new observing modes
    • set-up of optimized calibration plans
    • contribute to the operations-readiness of the upcoming generation of VLT(-I) and ELT systems.

The successful candidate will be member of the ESO Science Faculty, with an appointment at the level of Assistant or Associate Astronomer. S/he will be expected and encouraged to actively conduct astronomical research.

Functional duties are carried out for the equivalent of up to 105 nights per year at the Observatory, in either day-, night- or 'classical' shifts on site. Shift length is variable, on average about 8-10 nights on site, followed by the same amount of nights rest time at home. Functional work required and pursued at the ESO campus in Santiago accordingly reduces the required nights to be spent on site.

The rest of the time is spent on personal scientific research at the ESO campus in Santiago. ESO provides various types of financial support to its faculty members, including but not limited to: conference participation and organization, scientific visits, PhD studentships.

Reports to:

The Head of the Paranal Science Operations Department in Chile.

Key Competences and Experience:

We seek a staff astronomer with excellent observing and/or operational experience in areas relevant to VLT(-I) and ELT instrumentation. Continuous expertise exchange between the astronomical community and ESO is important. In this context, applications by colleagues on temporary secondments from their home institution are welcome.

Candidates with a strong background in state-of-the-art observing techniques available at Paranal will be given particular consideration. Such techniques include interferometry and extreme adaptive optics, high resolution and multi-object spectrosopy, time-resolved photometry, etc in the optical and near-to-mid infrared wavelength regions. A keen interest in quality control of astronomical data is required.

The ideal candidate will be an active researcher and have excellent observation-oriented research records, will be familiar with instrumental, data analysis, archiving and/or observational techniques, and must be conversant with at least one major data reduction package such as IRAF or IDL. Good working knowledge of python is a must.

Candidates should preferably have a proven ability to identify technical issues and potential risks, and experience with real-time troubleshooting. Very good self-organization and time management is a must, coupled with the ability to prioritize multiple tasks. Communication and interpersonal skill are required, with the ability to adapt and to work efficiently in a multi-cultural environment, both independently and within a team.
