The "Centro de Estudios de Física del Cosmos de Aragón" (CEFCA) invites applications for a staff  position of "Data Management Researcher – Pipelines" for the management and development of the software for processing the data produced at the Observatorio Astrofísico de Javalambre (OAJ).

CEFCA is an independent research institute located in Teruel, Spain, whose main responsibilities are the development, operation, management, and scientific exploitation of the OAJ, as well as the processing and storage of the data produced by its astronomical facilities. The main telescopes at the OAJ are the 83cm Javalambre Auxiliary Survey Telescope (JAST80) and the 2.5m Javalambre Survey Telescope (JST250), both of them having large fields of view (FoV) and being equipped with panoramic instrumentation.

JAST80 has a FoV diameter of 2 deg and a panoramic camera, T80Cam, with a large format CCD of ~9.2k x 9.2k pix. The T80Cam@JAST80 system provides an effective FoV of 2 deg2. Apart from a 20% of Open Time dedicated to competitive P.I. projects, since 2016 JAST80 is primarily devoted to conduct the Javalambre Photometric Local Universe Survey (J-PLUS), whose second data release of over 2000 deg2 was offered to the community in 2020 (DR2).

The data from T80Cam@JAST80 is being used also as a test-bench for the Javalambre Panoramic Camera (JPCam) already installed at the JST250 and currently in commissioning phase. The system JPCam@JST250 provides a 4.7 deg2 FoV with 14 CCDs identical to that of T80Cam. JPCam hosts a complete new set of 54 filters of ~140Å width covering the whole optical spectral range plus two broader filters at the blue and red ends to carry out the Javalambre PAU (Physics of the Accelerated Universe) Astrophysical Survey (J-PAS). J-PAS will produce photo-spectra of hundreds of millions of astronomical objects with a wide range of applications in Astrophysics and Cosmology. In addition, since CEFCA is an official leading node of the Ground Segment OU-EXT of the ESA Euclid mission, JPCam@JST250 will conduct the Javalambre-Euclid Deep Imaging Survey in g-band (JEDIS-g) in the next years.

The Unit for Data Processing and Archiving (UPAD) at CEFCA is the department responsible for the design and implementation of the hardware and software to conduct the archiving and treatment of the OAJ images and the by-products from their analysis. To achieve this goal, the UPAD consists of astronomers, software engineers and hardware engineers working in close collaboration. The UPAD team is developing its own data reduction and data processing pipeline making use of common third-party open software like Python, Astromatic software (SExtractor, Scamp, SWarp, PSFEx) and photo-z codes like LePhare. Currently, the pipeline is in a very advanced version and has been used for the DR1 and DR2 of J-PLUS and the public data release of the mini-JPAS project (mini-JPAS PDR201912). In addition, UPAD has also developed its own tools to provide easy and flexible access to the data produced at the OAJ. The UPAD is in continue development and improvement of the data processing tools to meet the stringent scientific requirements of projects like J-PLUS, J-PAS and JEDIS-g.

CEFCA is seeking for a post-doctoral researcher with long experience in massive data reduction of optical images. The successful candidate will join the UPAD team and will be responsible, in close collaboration with UPAD software and hardware engineers, for the data reduction and data processing of all the data coming from the scientific instruments of the OAJ.

The successful candidate will become full member of the J-PLUS and J-PAS collaborations. As an important benefit, after three years of contract in this position, the researcher will get the "builder" status for the J-PLUS and J-PAS collaborations, hence having the right to appear as author of all the publications of both projects. In addition, as CEFCA staff, the successful candidate will have the right to become Euclid member.
