What you will do

• Design and consolidate spacecraft operational concepts covering inter-satellite links, operational modes, onboard autonomy and FDIR.
• Own the operations handbook, FOP catalogue, flight rules, mission database requirements, constraints and configuration control.
• Define spacecraft configurations, command sequences, telemetry expectations, readiness criteria, hold and abort criteria, contingency actions and post-manoeuvre assessments.
• Coordinate end-to-end tests and operational rehearsals, validating procedures against the Mission Control System and test environments.
• Prepare and execute LEOP and commissioning plans as a system-level representative through handover to routine Operations.
