About this job

Sapienza Consulting is recruiting an End-to-End Simulations Support to EOP for Sapienza to work on our Customers Site (ESA-ESTEC).

Sapienza has been a partner of ESA for almost 30 years, and we pride ourselves in supporting a wide range of missions including Galileo, MTG, Copernicus and ExoMars. Our team is international with activities across the U.K., the Netherlands, North Macedonia, Belgium, Luxembourg, France, Germany, Italy and Spain.

Responsibilities

• End-to-end (E2E) simulations support to the Future Missions and Instruments Division (EOP-FM) for Mission and System Studies. The Contractor will report to the H/ Mission and System Studies Section
• Support the definition and development of the End-to-End (E2E) Mission Performance Simulators for future EO missions
• Contributing to ensure the technical coherency and completeness of the simulation of the observation system, including, as needed, functional analysis, system level budgeting, system performance analyses, modelling of spacecraft and/or payload subsystems and related data processing to meet system and mission requirements
• Install and use those E2E simulators on the EOP-FM IT infrastructure for mission performance evaluation and system trade-offs for future EO missions
• Ensure consistent evolution and maintenance of the E2E simulators and proper configuration and storage of the relevant input/output datasets
• Initiate and support work in the area of modelling of system/sub-system aspects (spacecraft, payload, ground processing) for E2E simulators and System Engineering Tools
• Support the development of generic building blocks and modules, and aim at maximum synergy and reuse of those building blocks and modules from one E2E simulator to the next making use of ESA OpenSF infrastructure (http://eop-cfi.esa.int/index.php/opensf).
• Participate to the development of System Engineering Tools for preliminary analysis and sizing of future EO missions
• Use the above System Engineering Tools for system trade-offs, preliminary sizing and evaluation of future EO missions The tasks are twofold: Task 1 –E2E Simulations for Future EO missions, related to the definition, development and exploitation of E2E simulators, aiming at a coherent and representative modelling of each element of the system (satellite, payload, ground processing), contributing to the E2E mission performance, maximizing the synergies and reuse of building blocks from one simulator to the next:
• Support definition and development of the E2E Mission Performance Simulators, including the elaboration of SOW and technical specifications, participation to progress meetings and reviews
• Contributing to ensure the technical coherency and completeness of the simulation of the observation system, including, as needed, functional analysis, system-level budgeting, system performance analyses, modelling of spacecraft and/or payload subsystems and related data processing
• Install and use the E2E simulators on the EOP-FM IT infrastructure for mission performance evaluation and system trade-offs for future EO missions
• Provide feedback from E2E mission performance simulations and optimisations to the spacecraft and mission design
• Ensure consistent evolution and maintenance of the E2E simulators, configuration and storage of the relevant input/output datasets
• Initiate and support work in the area of modelling of system or sub-system aspects (spacecraft, payload, ground processing) for E2E simulators and System Engineering Tools
• Support the development of generic building blocks and modules, and aim at maximum synergy and reuse of those building blocks and modules from one E2E simulator to the next making use of ESA OpenSF infrastructure
• Task 2 –Support related to the definition, development and exploitation of system engineering tools for Future EO missions:
• Participate to the development of new System Engineering Tools for preliminary analysis and sizing of future EO missions, ensuring a coherent and representative modelling of each element of the system (satellite/platform and its subsystems, payload, ground processing) contributing to the system performance
• Participate to the evolution and maintenance of the existing System Engineering Tools used
• Use the above System Engineering Tools for system trade-offs, preliminary sizing and performance evaluation of future EO missions
• Provide feedback from mission optimization to the spacecraft and mission design

Profile

• Master’s degree in a relevant technical or scientific discipline (e.g. Space system engineering)
• At least 4 years of relevant experience
• General knowledge of ESA Earth Observation missions
• Good communication and technical writing skills
• Good organization skills
• Capability to coordinate a large amount of inputs, synthesise, summarize and draw conclusions
• A proactive approach, with initiative and capability to work independently
• Problem-solving creative-oriented attitude
• Solid background in IT and computer programming
• Good knowledge of MATLAB/ Python is required; knowledge of other programming languages is an asset
• STK, MS Excel and CAD software knowledge is an asset
• Experience in modelling and simulation observing system characteristics (spacecraft, payload, ground processing, orbit…) and how they impact mission data quality and relate to system requirements and scientific goals is desirable
• Experience with end-to-end mission performance simulation for EO missions is required
• Knowledge of error propagation techniques is an asset
• Proficiency in the English language (spoken and written)
• Candidates must be eligible to work in the EU
