INSA is a leader company in Aerospace Engineering and Scientific services with more than 45 years of experience working for NASA and 35 years working for ESA. INSA seeks a candidate for a postion of Support to Science Operations Gaia located at ESAC MadridSpain. The Gaia mission is planning to map to microarcsecond accuracy 1 of the stellar population of our galaxy that is around one thousand million objects. Each object will be seen about 100 times over the fiveyear mission. The data reduction of the 100 Terabytes of downlinked data is estimated to require a Petabyte storage system. The processing will be community wide effort performed by the Gaia Data Processing and Analysis Consortium DPAC in which ESAC plays a coordination role. The ESAC team is forming Gaias Science Operations Centre SOC and is heavily involved in DPAC especially in the overall architecture and the core processing. The core processing includes initial data treatment and the Astrometric Global Iterative Solution AGIS to solve for the many unknown astrometric parameters. The processing is distributed over five locations and ESAC will form the hub for data exchange via the Main Database. This main database will form the input for all processing and will be augmented with the output of all processing to arrive at a new version. The production of processing software for Gaia has started and will continue through operations to final catalogue production in 2019. The SOC maintains core software as well as receiving packages from external entities to be integrated and run in SOC. For any candidate experience in interacting with the science community would be an advantage. The selected person must be willing operate in a team environment and to travel. Good interpersonal and communication skills are an advantage. The person should be comfortable in an international working environment and be fluent in English, one of the official languages of ESA. Specific tasks requirements for this position Work is to be carried out on the core systems provided by SOC including the Main Database and GaiaTools. These are large bodies of code and the chosen candidate will be required to quickly come to grips with the code base and implement big fixes and enhancements. The chosen language for the Gaia Core processing is Java and requires candidates to possess strong Java skills. Knowledge and experience in at least some of the following is essential large DBMS, distributed processing, numerical and statistical techniques. The candidate should be aware of required documentation for a large project. Experience working with large data volumes, ICDs, data dictionaries would be an asset.A scientific background is a strong advantage. Specific qualification requirements University degree or equivalent in computer science or related fields Basic educational or workacquired knowledge of astronomyphysics and standard numerical methods and techniques would be a strong asset Specific knowledge is required in the following areas ECSS standards for software development JDK 1.7 RMI Generics OO design Distributed processing Numerical programming in Java JUnit Eclipse Ant JDBC DBMS interaction Subversion Large Databasesdata processing 1TB In addition knowledge of the following would be beneficial LaTeX Applications Interested candidates should fill in and send Recruitment Form OEESARECRUITMENTFORM.doc to tarsicio.martinesa.int by 15022013.
