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.

CTA Consortium Positions

The Centre for Space Research at North-West University, Potchefstroom, South Africa, is inviting applications for a postdoctoral research associate in high-energy / multi-wavelength / multi-messenger astrophysics. The successful candidate will work in the group of Prof. Markus Boettcher and is expected to carry out research in astrophysics relevant to the group’s active involvement in H.E.S.S. and CTA. The candidate must have obtained his/her Ph.D. not more than 5 years before the starting date of the appointment, with research experience either in high-energy astrophysics theory or multiwavelength observations. Applicants with experience in radio interferometry data analysis for a possible link with the MeerKAT project in South Africa, are also encouraged to apply.
The starting date is January 1, 2021, or any mutually agreed-upon date thereafter.
The appointment will be initially for one year and may be extended to up to 3 years, depending on satisfactory performance and availability of funds. Interested applicants please send a CV, list of publications, statement of  research experience and interests, and the contact information of 3 references,  to Markus Boettcher ( by October 10, 2020.

The High-Energy Astroparticle Group of the Particle Physics Department of IRFU-CEA Paris-Saclay
is calling for applications for a two-year Postdoctoral Research Position.
The group is involved in the H.E.S.S. array and the CTA project. On H.E.S.S., the group has expertise
in dark matter, primordial black holes, transient sources and other topics. It contributes to the Medium
Sized Telescopes of CTA with major contributions to the NectarCAM camera and mirror design.
The IRFU institute has a broad expertise in nuclear and particle physics, astroparticle physics,
astrophysics and cosmology. It has also a well-recognized expertise in building detectors for colliderbased
experiments such as ATLAS and CMS, satellites (XMM, INTEGRAL) or astroparticle physics
The successful candidate will be involved in the NectarCAM project for CTA and the physics program
of H.E.S.S. and CTA. He/she will be responsible for the verification of scientific performances at the
NectarCAM integration site. He/she will contribute software development for the calibration, data
quality monitoring and analysis of data of the NectarCAM instrument. The qualification model of
NectarCAM is expected to be installed early 2022 at the Northern Site of CTA. The candidate will thus
have the opportunity to work on the early science of CTA.
Young scientists are particularly welcome to apply. To qualify, candidates are required to have a PhD
in Physics. Candidates should have programming skills in C, C++ and python and possibly be familiar
with data analysis in Imaging Cherenkov Telescopes. Experience in testing equipment and performing
laboratory experiments is considered an asset.
Interested applicants should submit
• a curriculum vitae including the description of research experience,
• the list of publications
• contact information of two reference persons.
The limit for application is October 15 2020.
Applications should be sent by email to: (Dr Jean-François Glicenstein, PI of NectarCAM) (Dr François Brun)
