We provide very competitive compensation, attractive benefits, and a great work environment with lots of opportunities for professional growth. JOB DESCRIPTION The XMMNewton Science Operations Centre SOC, located at the European Space Astronomy Centre ESAC, is, since March 2012, responsible for the scientific data processing of raw data products obtained from the XMMNewton satellite telemetry, done with a dedicated Pipeline Processing System PPS. The final products are archived and made available to the scientific community. The processing may include interaction with several scientific institutes of the consortium Survey Science Centre SSC in Europe and shared responsibility for data quality screening of the products and with the Centre de Donnes astronomiques de Strasbourg CDS, for data crosscorrelation. PPS is a subset of the Scientific Analysis System SAS, an interactive analysis package distributed to the observers for optimum scientific exploitation of the XMMNewton observations performed. The individual SAS programs, known as tasks, are mostly written in C and Fortran 90. Wide use of the Perl scripting language is made for concatenation of tasks in metatasks. PPS is composed of modules and scripts written also mainly using Perl, but also Python, Cshell and SQL. It uses Sun Grid Engine SGE for scheduling and management of jobs on a computer farm. A Database system Postgres SQL is used for storing toplevel pipeline configuration, and accessed by web management tools for steering and monitoring pipeline processing. A data transfer system DTS takes care of all the data moves, including packing and unpacking of data, between the different nodes involved in the processing, including the SSC and the CDS. The maintenance and further development of the SAS at the XMMNewton SOC is a responsibility of the SOC Science Support Team SST. Currently, the SAS Team is the unit within the SST in charge of the SAS. The postholder of this position will be a member of the SST and part of the SAS team. In July 2013, the SOC took over from SSC full responsibility for future PPS development and maintenance. Scientific requirements and priorities are set by the Pipeline Scientist one of the SST community support scientists following recommendations from the Project Scientist, who is advised by the Users Group. Responsibilities Duties Tasks The main service activities of this position may include but are not limited to, Software maintenance of the whole PPS XMMNewton Pipeline Processing System. PPS comprises o PPS modules, suite of Perl scripts containing the whole of the data reduction schemes for all the XMMNewton instruments and modes o Pipeline Control Management System PCMS, the control unit using a Sun Grid engine to distribute the processes across as many processors as available for maximizing the processing efficiency o PCMS DB, a Postgres Database storing all the configuration information o RUNDAT DB, a Postgres metadata storing processed data information o Pipeline Operations Engine POE, a web management tool for operating and monitoring the data reduction execution o Data Processed Screening System DPSS, the system used by screeners for efficient manual data quality and problem screening o Data Transfer System, used for transferring data between the different SSC nodes for screening, and for transfer and return of source lists to the Archival Catalogue and Database Subsystem ACDS in Strasbourg for crosscorrelation against archival catalogue data. Data Processing of the XMMNewton Data, including all of the following o running PCMS from raw Observation Data Files ODF for pointed observations to event files, images, spectra, lightcurves, source lists, etc, o running PCMS from raw Slew Data Files SDF for slew observations to images o generation of serendipitous source catalogues from the generated source lists, both for pointed as for slew observations o in general, support and coordination of Science Products Generation o delivery of the processed, screened Science Products to the XMMNewton archive Completeness checks of the Science Products, including the screening reports before delivery to the XMMNewton archive Maintenance tasks will include both first and second line maintenance. The post holder will keep a strong interaction not only within the SAS team, but also with the SOC and SSC screeners, as well as with the CDS. Maintenance activities include the setup and run support to the several pipeline chains eventually under use Operational, Reprocessing, Validation, Development. The post holder will be integrated in the SAS team, and as such, keep the flexibility to assume eventually also SAS maintenance or integration activities, not exclusively linked to the Pipeline Processing System. Qualifications University degree or equivalent in computer science or a related field. Background in a scientific discipline is desirable. Required knowledge Specific knowledge is required in the following areas Proven experience in the development andor maintenance of space observatory science analysis systems is an advantage. The candidate should be open minded and be able to understand the different subsystems as a whole integrated systems. Proven experience on data processing systems for space astronomy missions. Experience with Data Base management tools mostly POSTGRES and protocols for information access from SOC systems. Good command of modern programming languages CC, F9095, Perl, TclTk, Good knowledge of UNIX operating system. The selected candidate must be willing to operate in a international team environment. Good interpersonal and communication skills are an advantage. Candidates should be systemminded, flexible and able to work as a member of a small interdisciplinary team. The contractor should be comfortable in an international working environment and be fluent in English, one of the official languages of ESA. Other Information The service shall be provided during normal office hours. Location and reporting Together with other XMMNewton SOC staff, the Contractors key person will be based at ESAC. WHAT DO WE OFFER? As soon as they join the organization our professionals are given the chance to tackle technological challenges in an innovative environment, to work in multidisciplinary teams and deal directly with clients. This helps them to mature quickly as professionals. We provide continual topup training to keep our career professionals perfectly abreast of all technologies used.
