Astronomer / Near-Earth Object (NEO) Observer

Company Details

Expanding frontiers

Main Duties:

  • Support the development, testing and integration of the data processing software for Flyeye, Test-Bed Telescopes (TBT) as well as other telescopes available to the Planetary Defence Office.
  • Support the testing, integration and commissioning of the Flyeye telescope. In particular: review and update documentation, analyse test image data, preparare plans for testing and commissioning, participate in factory and site acceptance tests.
  • In cooperation with the Space Debris team, support the testing and use the two TBTs for survey and follow-up observations.
  • Remote scheduling the TBTs and Flyeye telescope and ensure proper data analysis.
  • Preparation and coordination of astrometric observations of NEOs for all collaborating telescopes.
  • Perform astrometric measurements when needed.
  • Support the preparation of physical properties observations of NEOs, when needed.
  • Support all observation-related discussions in the Planetary Defence office.
  • Inform the observations manager of any issues.
  • Present observational successes at conferences and workshops.
  • The activities will mostly be done during nominal working hours; however, you are expected to do night and/or weekend shifts, such as:
    • Typically, 4 nights per month are dedicated to the use of ESA’s OGS telescope.
    • At least once per month urgent observations may require a (partial) night shift.
    • Part of the Flyeye testing, integration, commissioning and/or calibration campaigns will be carried out at night.
    • On-call service for the Flyeye operations: you may be contacted in case of emergency, e.g. you may be required to restart or update the foreseen schedule.
    • Most of the observations are executed remotely. However, you are expected to travel to participate in relevant meetings and observational campaigns if required.


  • Master’s degree in physics, astronomy or closely related fields. Higher level education (e.g. a Ph.D. in a related discipline) is an asset.

Professional Experience:

  • From junior to senior, preferably senior

Technical Requirements:

  • Expertise in using optical telescopes and their data reduction is mandatory.
  • Experience in carrying out NEOs observations and astrometric analysis is an asset.
  • Expertise in optical detector system integration, test, validation and calibration is an asset.
  • Familiarity with software languages, in particular Python.

Language Skills:

  • Fluency in English, both written and spoken, is mandatory.

Personal Skills:

  • Good communication skills.
