We invite expressions of interest for postdoctoral positions at the Italian Institute for Nuclear Physics (INFN) in Rome, Italy. The postdoctoral positions will be funded under the Italian Fund for Science (FIS) Starting Grant Eyes-on-GR, whose goal is testing general relativity with multiband gravitational-wave observations.

We are particularly eager to receive expressions of interest from candidates with experience in (i) data analysis with current and next-generation detectors (ii) modeling deviations from general relativity in modified theories of gravity and horizonless compact objects.

The postdocs will join the new research group Eyes-on-GR led by Dr. Elisa Maggio at INFN Rome, Italy. INFN Rome is located inside Sapienza University, one of the largest Universities in Europe. The postdocs will have the possibility to join the Virgo, Einstein Telescope and LISA groups in Rome. The INFN Virgo Rome group has about 35 researchers including PhD students, postdocs and 18 faculty.

The postdoctoral positions are expected to start between Fall 2026 and Spring 2027 and can last 2+1 years. All candidates must hold or soon be completing a Ph.D. in Physics, Astronomy or Astrophysics. Interested candidates should send (i) a motivation letter, (ii) a curriculum vitae, indicating the date the PhD was or will be awarded (iii) a research statement, and (iv) two contacts for reference letters.

Expressions of interest should be sent via the Google Form in the external link, and reference letters should be sent to Elisa Maggio (elisa.maggio[AT]roma1.infn.it).
Candidates are encouraged to apply as soon as possible. The deadline for full consideration of the expressions of interest including reference letters is June 19th, 2026.

Please, fell free to forward this announcement to potential candidates. For any other information, please do not hesitate to reach out to Elisa Maggio (elisa.maggio[AT]roma1.infn.it).

Open position for: Research associate (“logisticien.ne de Recherche”) (Gravitational waves instrumentation) University of Liège for a permanent contract (full time) starting ideally start on the 1st of September 2026. Application deadline: May 30th, 2026.

Context and missions
The Einstein Telescope (ET) will be Europe’s most advanced observatory for gravitational waves. It will allow researchers to hear black holes mergers and learn about the early universe.

The department of aerospace and mechanical engineering of University of Liège hosts the ET-CRISTAL facilities. ET-CRISTAL is an R&D facility for demonstrating crucial aspects of ET-Low Frequency. It uses innovative approaches for seismic isolation, i.e. an inverted pendulum stage on top of active seismic isolation platform and contact-free radiative cryogenic cooling of a large-scale cryogenic mirror. ET-CRISTAL is a Center of Excellence for the sub-system comprising the mirror, its suspension system, the vibration Isolation system, and cryogenic cooling of the mirror.

The Precision Mechatronics Laboratory within the Department of Aerospace and Mechanics (A&M) and from the School of Engineering at the University of Liège invites applications for an open position as a research associate in gravitational wave instrumentation at ET-CRISTAL. The facilities are installed at the Space Center (CSL) of the University of Liège and the main research offices of the Precision Mechatronics Laboratory are located within the Department.

As a Research Associate, you will have as missions to:

• Lead the management of ET-CRISTAL facilities together with the Scientific Director (Prof. C. Collette), including research logistics, participation and tutoring of Master and PhD students as well as fellow researchers.
• Develop and support research activities in fields relevant to ET-CRISTAL
• Contribute to securing new funding and develop new collaborations

Application requirements

• To hold a PhD in engineering, or an equivalent experience.
• To have proven experience in one or several of these fields:
  • cryogenic inertial sensors
  • low frequency seismic isolation
  • radiative cooling
  • thermal noise modeling
  • Newtonian noise

You must also have strong project management skills, as well as excellent written and oral communication skills in English and, if possible, in French. You should be able to take the initiative and be skilled in negotiation and consensus-building.

We offer

• A pleasant and dynamic work environment with a wide variety of assignments
• Significant freedom in how you organize your work and a degree of autonomy in decision-making
• Salary based on established pay scales and pre-determined pay Progression plans
• The opportunity to support fundamental and applied research related to a Major Big Science instrument in an international Environment

The Graduate School of Physics at Université Paris-Saclay, France, is launching the second call of its new postdoctoral fellowship program: UPSaclay-STAR-φ, supported by the EU Marie Skłodowska-Curie COFUND. The program will recruit up to 41 international postdoctoral researchers over two calls, for 24-month projects in one of the 40 laboratories of the Graduate School, working on various fields from fundamental to applied physics. The CMS group of CEA-Saclay IRFU (contact: julie.malcles(at)cea.fr) is a possible host group, among others. The application deadline for the first call is July 15, 2026 at 5pm and the expected start of fellowships early 2027 (flexible).

Applicants will have to propose their own research project, with freedom of choice (in agreement with the thematics of interest of the CEA-Saclay/IRFU CMS team).

The CMS CEA-Saclay group has contributed to the design, construction and operation of the ECAL of CMS and is involved in the upgrades of the CMS detector (ECAL, MTD and HGCal).
The group is involved in the ECAL calibration and our analysis activities in Run3 include Higgs to Zy, double Higgs in the bb tautau channel, deep learning for ECAL and MTD reconstruction and various topics related to the diphoton channel (ttH/tH and its CP properties, high mass searches, interference to constraint the Higgs boson natural width with the mass measurement).

To be eligible, applicants must not have resided or carried out their main activity in France for more than 12 months during the 3 years preceding the deadline for applications.
