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.

* Space Segment Requirements/Verifications:
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

* Subsystem and Payload Integration:
Manage critical interfaces between the satellite bus and the payload, driving resolution of technical conflicts across hardware and software teams.

* AI&T Oversight:
Supporting Assembly, Integration, and Testing (AI&T) flows, guiding environmental ground testing (vibration, thermal vacuum) and launch campaign preparations.

* Supplier Management:
Direct the acquisition and management of major bus contractors, payload providers, and subsystem suppliers, including statements of work (SOWs) and acceptance reviews.

* Risk Management:

Track technical performance metrics, define risk mitigation strategies, and manage the Integrated Master Schedule (IMS) to prevent schedule slips.

* Customer Interface:
Serve as the primary technical point of contact for stakeholders, communicating design status and handling programmatic deliverables

* Expertise in developing systems architecture and performing systems integration, verification, and validation (V&V) activities.

* Ability to contribute to corporate Systems Engineering policy and process definition and implementation.

* Demonstrated ability to work and communicate with technical and specialty subject matter expert engineers to drive systems engineering products.

* An active Secret or above U.S. Security Clearance is required

Preferred Qualifications

Technical Knowledge:

* Solid understanding of spacecraft subsystems (CDH, Comm, EPS,GNC, Prop, SMS, TCS)

* Demonstrated experience establishing and managing Space Segment TPMs, aggressively tracking subsystem margins, and implementing corrective action plans when technical budgets approach critical thresholds.

* Knowledge of orbital mechanics, space environment, and mission design.

* Familiarity with space industry standards and regulatory requirements.

* Understanding of systems engineering processes and lifecycle management.

* Experience with spacecraft test and integration processes.

Skills:

* Strong technical leadership and decision-making abilities
