VN 20/25 Optical Instrument System Engineer

EUMETSAT is developing the EUMETSAT Polar System of Second Generation (EPS-SG) that includes Metop-SG A and Metop-SG B satellites developed and procured through ESA. The EPS-SG mission will monitor weather and climate from the mid-morning polar orbit over a period of 21 years starting in 2024/25, based on three successive pairs of Metop-SGA/B satellites.

With the exception of IASI-NG and METimage, all Metop-SGA instruments are developed and procured under ESA responsibility, including two optical instruments, the Multi-viewing, Multi-channel and Multi-polarisation Instrument (3MI) and the Copernicus Sentinel-5 UV-to-SWIR spectrometer.

Reporting to the EPS-SG Instrument Systems Manager, the EPS-SG Optical Instrument System Engineer will follow up the ESA-led development of the 3MI and Copernicus Sentinel-5 instruments, acquire, maintain and share in-house knowledge on instrument design, performances and operations aspects. As a member of the EUMETSAT Instrument Functional Chain Teams involving also instrument scientists, system, ground segment and operations preparation engineers, he/she will support the development, operations preparation and commissioning of the end-to-end 3MI and Sentinel-5 instrument chains covering all functions from instrument commanding to delivery of products to users.


  • As the EUMETSAT technical interface of the ESA 3MI and Sentinel-5 instrument project teams, ensure day-to-day coordination for the timely acquisition of information and knowledge on design, test results, expected performances, and operations of the 3MI and Sentinel-5 instruments by EUMETSAT;
  • Maintain and share this information and knowledge within the EUMETSAT 3MI and Sentinel-5 Instrument Functional Chain Teams;
  • Follow-up the assembly, integration, on-ground calibration and testing of the 3MI and Sentinel-5 instruments and relevant aspects of subsequent Metop-SG A satellite tests carried out under ESA responsibility;
  • Analyse and assess results of 3MI and Sentinel-5 on-ground calibration, testing and qualification and identify issues having potential implications for the design, development, performances, operations and commissioning of end-to-end instrument chains;
  •  As a member of the EUMETSAT 3MI and Sentinel-5 Instrument Functional Chain Teams, support the assessment of the implications of non-conformances for the development and validation of instrument data processing, operations and commissioning;
  • Follow up the development of 3MI and Sentinel-5 Level 1 processing algorithms associated ground prototype processors and instrument data simulators, and assess their consistency with the instrument development and their suitability to support the development of operational Level 1 processing chains;
  • Manage the cooperation with CNES for the provision of support to the development of 3MI Level 1b processing, vicarious calibration and performance assessment tools and other relevant EUMETSAT contracts requiring knowledge of the design 3MI and Sentinel-5 instruments;
  • Support the operations preparation and commissioning of the Sentinel-5 and 3MI end-to-end instrument chains in cooperation with ESA, focusing on instrument operability and performance validation;
  • Participate in reviews at 3MI and Sentinel-5 instrument, Metop-SG A satellite and EPS-SG system levels;
  • Support reporting to EUMETSAT management and Member States.
