Employment Opportunities

CTA is a global endeavour to build the world’s largest and most sensitive high-energy gamma-ray observatory, which is expected to cost in the region of €300 million for equipment and an additional 1,500 person-years of effort. Imminent site preparations and construction of CTA’s first telescopes have prompted a significant recruiting effort.


The project office is responsible for the functions of general project management, technical coordination and system integration for the CTA construction project. While most positions will be located in Bologna, some will be located on the CTA sites in Chile and La Palma.


In addition to CTAO gGmbH/Project Office employment opportunities, this page features some of the available CTA-related positions with CTA’s Consortium institutes.

CTA Consortium Positions

The Institute of Space Sciences is offering two Junior Postdoctoral Fellowships.

Candidates should be within 2 years after the PhD, excluding maternity/paternity leaves. The appointments are for 2 years. The fellow is expected to develop her/his independent research and to interact with one or more of the research lines within the Institute.


Mobility rule: candidates should not be affiliated to the Institute of Space Sciences nor have carried out her/his PhD or initial postdoc at the Institute.
To apply, interested persons should send (to the contact below and with subject Junior Postdoc 2021)


  • Curriculum vitae
  • Full publications list (for candidates working within large collaborations, please distinguish those in which you have done a substantial contribution, and explain which was it)
  • A minimum of 2 reference letters (to be sent separately by email to the address below)
  • A research statement (maximum 3 pages)

The research statement should include commentary on the appropriateness of developing your research line at the Institute, how this can positively impact your career, and the prospects you see for collaboration with the established groups here.


Email applications are welcomed. Positions will be open until filled, but initial screening will start on October 30th and a decision is expected before the end of the year. Starting date during 2022 is flexible, but sooner dates are preferred.


The Institute of Space Sciences is an institute of the Consejo Superior de Investigaciones Científicas (CSIC), and is affiliated with the Institut d’Estudis Espacials de Catalunya (IEEC).

As part of a project to develop a new camera for the CTA’s Large-Sized Telescope (LST) based on silicon photosensors (SiPMs) and associated innovative readout electronics, the Department of Particle Physics (DPNC) at the University of Geneva is seeking an electronic engineer with a specialization in ASIC design. She/he will be involved in the specification, design and schematic, layout, test and qualification, commissioning and operation phase of the silicon photomultiplier amplification and analog signal shaping chips within the framework of the LST Advanced SiPM Camera project. She/he will perform ASIC development and prototyping for the front-end electronics of the LST Advanced SiPM Camera, carry out the commissioning, the monitoring of operation and the study of the performances of ASIC for the front-end electronics as well as develop HDL firmware blocks (FPGA target) to configure and interact with the designed ASICs and test PCBs to test and characterize the designed ASICs.



  • Engineering degree or equivalent with additional training and relevant experience
    oriented towards electronics, computer science and development of ASICs suitable for
    particle physics.
  • A few years of professional experience in the development of complex ASICs.
  • Good knowledge of electronics and excellent knowledge of computer tools for ASIC design
    (Cadence) and simulation.
  • Mastery of VHDL and/or Verilog languages used in ASIC (digital synthesis) and FPGA
    firmware development.
  • Knowledge of printed circuit board design and a strong desire to learn in this field.
  • Ability to master the electronic and technical aspects of the FLARE: LST Advanced SiPM
    Camera project.
  • Written and oral proficiency in English and French to perform all tasks described in both
  • Mastery of office automation tools (Word, Excel, Powerpoint, Project, etc.).


Starting Date: September 2021.

The University of California, Los Angeles (UCLA) invites applications for a postdoctoral research position in the area of particle astrophysics and dark matter. While the candidate will carry out research with the GASP experiment, s/he might have the opportunity to perform complementary research with the currently operative ground-based gamma-ray experiment, VERITAS, and the next generation high-energy facility and  first ground-based gamma-ray observatory, the Cherenkov Telescope Array (CTA).


Candidates working in the areas of particle/nuclear physics, particle astrophysics or astronomy and having a strong background in experimental/instrumental techniques area encouraged to apply. A Ph.D., or equivalent degree, in physics or astronomy is required. The regular duration of the position would be two years, with the possible extension of one or two more years.


Applicants should send/email a CV and a statement of research interests (1-2 pages) to:

Professor Rene Ong

Department of Physics and Astronomy

University of California, Los Angeles

Los Angeles, CA 90095-1547


Applicants should also arrange for three letters of recommendations to be sent to the above email address.


Deadline: October 15, 2021 (applications arriving after this date will be considered if the position has not yet been filled).

The Astrophysics Department of CEA Paris-Saclay, IRFU, invites applications for a postdoctoral research position in the area of high-energy astrophysics in the context of the start of the construction of the CTAO’s telescope arrays and the first real data analysis.


The objective is to contribute to the improvement and go toward finalisation of the CTA data pipeline software, aiming at producing sky images from the telescope array data. The development will be made in the context of the early science phase of CTA, giving the opportunity to cover science subjects to be discussed with the candidate.


The candidates should hold a PhD in subatomic physics, astroparticle or astrophysics with a strong motivation in software and algorithm developments as well as formal code release and documentation, the understanding of experimental data and physics analysis. The software will be written in Python and experience in object-oriented programming is appreciated. The position is available from end 2021 for a period of up to 3 years.


The applicant should send the following documents in a digitized format to Thierry Stolarczyk, head of the group (

– A letter of motivation;

– A curriculum vitae, a list of relevant publications;

– The names of at least two references and at least two letters of recommendation


Deadline: Selection will start on October 1st, 2021 and will remain open until filled.
