End-to-End Instrument Processing Chains System Architect

Reference nr: 101

Location: Darmstadt, Germany

Application deadline: 23 September, 2015


RHEA is currently recruiting an End-to-End Instrument Processing Chains System Architect to support EPS-SG at our client’s premises in Darmstadt, Germany.


Tasks and Activities

The scope of work will include:

  • Ensure that the operational processors which are developed as part of the EPS-SG Ground Segment are consistent with the EPS-SG System architecture and able to meet the EPS-SG system requirements
  • Review and contribute to the preparation of the processing specifications (Product Generation Specifications (PGSs), Product Format Specifications (PFSs) and Auxiliary Data Specifications (ADS)) to confirm and ensure their consistency with the System requirements;
  • Review space segment and instrument documents (e.g. S2GICD, Instrument ICDs, APIDs/VCIDs allocation) to identify implications for the System when related to instrument data processing; review of instrument data processing algorithms and calibration concepts defined by industry with emphasis on their implications on data processing interfaces and architecture;
  • Review ground segment documentation dealing with requirements, design and technical analyses of relevance for data processing to ensure consistency with system requirements and design;
  • Assess implications of/contributions by the data processing chains to End-to-End (E2E) performance requirements (spectral, radiometric and geometric requirements) and contribute to the compilation of E2E performance budgets; any non-compliances with the EPS-SG System E2E performance requirements need to be identified and resolved;
  • Participate in formal reviews and technical meetings at system, space segment and ground segment level when relevant for instrument data processing;
  • Prepare documentation for System reviews;
  • Coordinate interdisciplinary meetings relevant for instrument data processing chains;
  • Support studies (internal or external) and the evaluation of their results when relevant for instrument data processing.


Skills and Experience

The following skills and experience are mandatory:

  • University degree in the domain of engineering, science, or equivalent;
  • At least 5 years of experience in engineering of on-ground data processing elements, including requirements specification, architecture and detailed design, definition of interfaces and testing concepts for space-borne observing systems as imaging and/or sounding instruments;
  • Demonstrated ability to perform analyses of a System (combined space and ground segment) top down and to perform syntheses.

The following skills would be highly desirable:

  • Experience in verifying and validating complex real-time data processing systems for space-borne observing systems as imaging and/or sounding instruments;
  • Experience in specification, development and/or procurement of instrument test data sets and processor prototypes for space-borne observing systems as imaging and/or sounding instruments;
  • Knowledge of relevant space-borne observation instruments (EPS-SG satellites will embark sounders and imagers from the ultraviolet to the microwave range, a scatterometer and a radio-occultation instrument);
  • Mission performance analysis, budgeting and verification for space-borne observing systems as imaging and/or sounding instruments;
  • Experience in specification of operational products for earth observation missions.



Preference will be given to candidates eligible for an EU or national personal security clearance at the level of SECRET or above.
