Euclid Mission OU-EXT scientific programmer (1.0 FTE)


Kapteyn Astronomical Institute


Rijksuniversiteit Groningen

OmegaCEN invites applications for a temporary position for a scientific programmer / researcher in the Euclid Organisational Unit External Data (OU-EXT) within the OmegaCEN center. OmegaCEN is the expertise centre for astronomical data science and information technology at the Kapteyn Astronomical Institute of the University of Groningen. The Kapteyn Astronomical Institute is the university’s department for research and education in astronomy, astrophysics and astronomical instrumentation.
The Euclid Mission is the European Space Agency's next cosmology flagship mission to be launched in 2022 aimed at studying the dark universe and cosmology. OU-EXT is part of the Euclid Science Ground Segment that delivers all space- and ground-based calibrated data ready for scientific analysis. It is being developed by a large international consortium including OmegaCEN-Kapteyn as a member of the Netherlands Research School for Astronomy (NOVA).
The Euclid OU-EXT team is an international team co-led by G.A. Verdoes Kleijn at Kapteyn Institute and includes team members at the Ludwig Maximilian University of Munich and Max Planck Institute for Extraterrestrial Physics.

Job description

Euclid’s External Data observing programme includes massive ground-based imaging surveys such as the Dark Energy Survey, CFHT, LSST, Pan-STARRS and the Javalambre Survey Telescope. The Organisational Unit External Data coordinates the multi-band photometric and astrometric calibration of these ground-based surveys, is responsible for the data quality assessment against Euclid requirements and for the software producing the products ready for combination with the optical and near-infrared data from the Euclid satellite. The EXT team at OmegaCEN has delivered, together with the EXT team at the Max Planck Institute for Extraterrestrial Physics and Ludwig Maximilian University in Munich, a qualified initial version of the software system for production. The coming 4 years, the international team will focus on finalising the software system for data validation, improving calibration algorithms, performing system integration and extensive qualification run and then do early operations around Euclid’s launch.

The appointee can be involved in:
● Development of framework software for software and data validation:
o Software for data quality assessment: automated and interactive
o Implementation of interactive visualisation
o Support infrastructure: interfaces between databases and pipelines

● Development astrometric validation and calibration:
o Algorithms
o Production code
● Qualification of data and related software through iterative cycles of testing and improvement
o Lead operations for massive data production and validation
o Test data releases.

The appointee will be embedded in a team of two dozen experts in information technology and astroinformatics. There is therefore some flexibility in the appointee’s existing balance between expertise in astronomical calibration algorithms and in software engineering. The team has two decades of experience in this area with technologies used in the Astro-WISE system and has a leading role in the Euclid Archive System and the national Science Data Center.


We are looking for the following qualifications and experience:

● a university degree in astronomy
● experience with astronomical image processing and software in the optical or near-infrared strongly preferred
● software engineering experience: setting up and maintaining development environments for software prototyping and software testing
● affinity with databasing, detailed software design and data modelling
● mastery of Python, C++ and XML, affinity with visualisation software, Jupyter
● proactive and independent working attitude
● team player, communicative, experience with distributed software project teams is a plus
● flexibility in dealing with different organisational cultures and structures
● prepared to travel several times per year to international partners
● good mastery of the English language.
