Responsibilities

Own the end-to-end delivery of the spacecraft from kick-off to final handover, ensuring compliance with mission specifications, technical baselines, and cost constraints.
Develop and maintain space segment schedule, budget, and resource plans.
Define, flow down, and trace the space segment technical requirements from mission-level objectives with support of Systems engineering.
Author the comprehensive Verification and Validation (V&V) matrix to systematically prove spacecraft compliance through analysis, inspection, demonstration, and environmental qualification testing.
Manage critical interfaces between the satellite bus and the payload, driving resolution of technical conflicts across hardware and software teams.
Support Assembly, Integration, and Testing (AI&T) flows, guiding environmental ground testing (vibration, thermal vacuum) and launch campaign preparations.
Direct the acquisition and management of major bus contractors, payload providers, and subsystem suppliers, including statements of work (SOWs) and acceptance reviews.
Track technical performance metrics, define risk mitigation strategies, and manage the Integrated Master Schedule (IMS) to prevent schedule slips.
Serve as the primary technical point of contact for stakeholders, communicating design status and handling programmatic deliverables.
