End-to-End Instrument Chains Performance Engineer

Reference nr: 872

Location: Darmstadt, Germany

Application deadline: 02 November, 2016


RHEA Group is currently recruiting an End-to-End Instrument Chains Performance Engineer to support the Jason-CS Programme at our client’s premises in Darmstadt, Germany.


Tasks and Activities

The scope of work will include:

  • Following-up performance requirements, allocation and budgeting performed by space segment and instrument providers.
  • Following up the definition and development of the on-ground instrument data processing specifications (e.g. algorithms and product formats).
  • Following up the development of the on-ground instrument data processing systems, test tools and test data.
  • Following-up and reviewing definition of approach for modelling of system performances, space segment and/or instrument providers; review of adequacy of related performance modelling tools.
  • Contributing to the preparation and analysis of the system performance budgets, collecting input from space segment, instruments and ground processing segment; reporting any non-compliances and following up resolution.
  • Contributing to the consolidation and maintenance of the system requirements, including tracing to space segment, instrument and/or ground segment requirements and tracking of the status of compliance; reporting any non-compliances and follow up resolution.
  • Supporting the consolidation of the verification approach for system performance requirements and contributing to the maintenance of the related verification matrix.
  • Contributing to the assessment of the ground data processing algorithms and Cal/Val algorithms developed as part of the Jason-CS ground segment and confirm that they allow meeting the System Performance Requirements; reporting any non-compliance and follow up resolution.
  • Supporting the validation of products and ground data processing algorithms.
  • Following up the verification, integration and acceptance of the on-ground instrument data processing elements.
  • Contributing to regular reviews of System, Space Segment, Instrument and Ground Segment documentation.
  • Participate in formal reviews and technical meetings at System, Space Segment, Instrument and Ground Segment level.
  • Providing input for / support preparation of documentation for System and Ground Segment level reviews.


Skills and Experience

The following skills and experience are mandatory:

  • University degree in the domain of engineering, science, or equivalent
  • At least 3 years of combined experience:
    • in the field of engineering of space and/or ground systems, in the area of Earth observation from space
    • in the field of end-to-end mission performance analysis, budgeting and verification for space-borne observing systems
  • Good knowledge of relevant space-borne observation instruments (Jason-CS satellites will embark a radar altimeter, a microwave radiometer, a GNSS receiver and a radio-occultation instrument)
  • Knowledge of ground data processing algorithms and ground processing environment

The following skills would be highly desirable:

  • Experience in verifying on-ground instrument data processing systems;
  • Experience in development of test data sets and processor prototypes;
  • 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.
