Job ref: N/A


The European Gravitational Observatory (EGO) seeks an optical physicist/engineer for the Virgo injection system (INJ), pre-stabilized laser (PSL), auxiliary system laser (ASL). EGO is a French-Italian consortium founded by INFN and CNRS to foster European collaboration in gravitational wave research. EGO is located in Cascina, near Pisa - Italy, and hosts and operates the gravitational wave detector Virgo, a 3 km-long laser interferometer (ITF). Virgo and the two LIGO ITFs in the US are the most large and sensitive gravitational-wave detecting instruments in the world. The Virgo project involves the collaboration of about 20 laboratories with more than 300 scientists, engineers and technicians in France, Italy, the Netherlands, Poland, Hungary and Spain.


The selected candidate will work as an Optical Physicist/Engineer within the EGO optics group. She/he will collaborate with other team members to the design, realization and commissioning of different Optical Systems related to the upgrade of Advanced Virgo Plus, in particular to the realization of the SHG sources for the ALS, and the improvement of Optics related to INJ and PSL subsystems. Other duties include:

  • Critically analyzing the design, the definition of requirements, the error budgets, the definition and verification of performances of the interferometer and optical benches, especially in view of next upgrades of the interferometer.
  • Proactively seeking problems and proposing solutions to solve issues found.
  • Possibly planning and implementing the required solutions for efficient long-term operations, as well as new upgrades for improving performances.
  • Monitoring technology development activities in the fields of optics, interferometry and laser systems.

  • The post may require the selected candidate work outside of normal working hours, sometimes including nights, weekends and public holidays, and may require shift work and participation in a regular on-call service, ability to adapt quickly and resourcefully to shifting priorities and constraints. It may happen to cope with technically difficult situations, and to work within strict deadlines.

    Essential required qualifications and experience:

  • A PhD related to experimental Optics or Optics/Opto-Electronics is required, with hands-on experience in Optics. PhD must have been earned within the past 5 years
  • Experience in the field of advanced scientific instrumentation at a University institute or similar institution, with operational experience
  • Knowledge in laser physics and Non-Linear Optics and scientific/industrial laser equipment
  • Proficiency in the operation of Optics-related control electronics and diagnostic instrumentation
  • Capacity to communicate efficiently with colleagues from different countries, good sense of team spirit and proactive attitude
  • Good knowledge of English
  • Knowledge of Python or Matlab programming languages and basic knowledge of UNIX/LINUX operating systems

Desired qualifications and experience

One or more of the following will be an asset:

  • Experimental knowledge of control systems
  • Competence with optical software design (Zemax or equivalent).
  • Working knowledge of Italian and/or French

General requirements

  • No criminal convictions
