• Review and approve RF designs, analyses, simulations, test plans, and verification results.
• Lead the development and execution of TT&C integration and verification plans , including component, subsystem, spacecraft-level, and end-to-end testing.
• Support spacecraft integration, test, troubleshooting, launch readiness, commissioning, and on-orbit TT&C operations .
• Lead resolution of complex RF and communications system issues and coordinate technical decisions across engineering disciplines.
• Establish and maintain TT&C architecture documentation, requirements, interface control documents, link budgets, CONOPS, trade studies, test plans, and verification matrices.
• Identify technical risks and develop mitigation strategies throughout the TT&C development lifecycle.
• Work with program and systems engineering leadership to establish team staffing, technical capabilities, and resource requirements for the RF/TT&C organization.
• Mentor engineers and develop the technical capabilities of the RF communications team.
