A Spanish leader company in Aerospace Engineering and Scientific services with more than 45 years of experience working for NASA and 35 years working for ESA seeks a candidate for a System and Software Engineering for Science Operations. Work Package Overview This work package is intended to provide a number of specialised services to support ESA in developing the Gaia missions Science Operations Centre at ESAC. ESAs Gaia mission is designed to create an accurate and complete astrometric catalogue which will serve for decades to come More than 1000 Million objects mostly stars in our Milky Way down to apparent magnitude 20 will be repeatedly observed from the second Lagrange point L2 during the satellites nominal lifetime of 5 years. This will yield a raw data volume of about 100 TB 1 PB total from which each stars position, trigonometric parallax, and proper motion for a smaller subset also radial velocity th will be determined to microarcsec accuracy typically 25 as for parallax at 15 magnitude. The data processing and catalogue creation is carried out by the Gaia Data Processing and Analysis Consortium DPAC formed by around 400 individuals and six main data processing centres distributed across Europe. The Gaia SOC at ESAC is an integral part of DPAC and plays a key role in designing the overall system architecture and developing and operating parts of the Core Processing systems viz. Initial Data Treatment IDT, First Look FL, and the Astrometric Global Iterative Solution. ESAC will also form the hub for data exchange via the Main Database MDB. This MDB 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 will continue through operations to final catalogue production around 2019. The SOC maintains core software but also receives packages from external entities to be integrated and run in SOC. For any service provider experience in interacting with the science community would be an advantage. The selected provider must be willing render the service in a team environment and to travel. Good interpersonal and communication skills are an advantage. The service provider should be comfortable in an international working environment and be fluent in written and spoken English, one of the official languages of ESA. Service Support Positions SSCO101210 Support to Gaia Operations. Service Specific Tasks Contribute to procedure writing and the implementation of those procedures Follow procedures and operate Gaia SOC systems Test SOC systems for the daily processing of raw Gaia data Test SOC systems for the generation of payload operations request Further test and scale SOC products such as MDB Participate in the optimisation of software processing Gather operational constraints for software running at SOC Interact appropriately with and support the providers of all software SOC systems Interact appropriately with the users of DPCE data products and other Data Processing Centres Assist in automation of SOC procedures nominally Gaia SOC will only be manned normal working hours. Contribute to the maintenance of the overall system, including configuration control and versioning Provide support for testing, particularly for EndtoEnd E2E and operational rehearsal campaigns. Report on operational activities including the gathering and presentation of processing summary statistics Output and Service Performance Monitoring ESA will formally define the service delivery in terms of delivery times, performance targets and similar measurable parameters Key Performance Indicators. This shall be agreed with the service provider and shall be assessed, and modified as needed, during regular progress meetings typically monthly. The service provider shall manage the service provision and provide ESA with the necessary data and corresponding evidence. The service provider shall be measured and assessed on the basis of Documents generated in the period at the dates required by the project milestones and internal plans. The assessed completeness of the documents and any analysis contained within. Reporting inlinein time with the approved schedule. Presentations made in the reporting period e.g. to astronomers at workshops Helpdesk tickets handled number and work effort associated with resulting investigations. Bug reports raised and analysed Working group attendance and presentations Interactions It is expected that the service support provider will be able to interact freely with any member of the Data Processing and Analysis Consortium DPAC. Interactions with general international community of astronomersusers are also expected via workshops and the helpdesk. Specific Qualification Requirements Preferred experience Past astronomical instrument or spacecraft support with a major international space or Groundbased observatory Support to the professional astronomical community for a spacebased mission Experience in operating large and distributed data processing systems Use of spacebased scientific data in support of science research. ECSS standards for software development Database interaction using JDBC Subversion Large Databasesdata processing 1TB LaTeX Positions covered by this package will require at least a graduate degree Masters or Ph.D. in a relevant subject area. Level of Service Support Start Date 1 June 2015 Support End Date 31 December 2016 Number of man years Estimated of about 1 man year per year Location It is expected that the service is provided at ESAC Other Information na APPLICATIONS Interested candidates should send cv and cover letter to seleccionisdefe.es. The job code must included on the subjet.
