  • Factory Acceptance Testing (FAT)
  • Site Acceptance Testing (SAT)
  • RF performance testing
  • End-to-end satellite-to-ground testing
  • Operational readiness demonstrations
• Lead RF troubleshooting, anomaly resolution, and root cause analysis during integration, test, launch, and on-orbit operations.
• Coordinate with satellite manufacturer teams to ensure compatibility between spacecraft RF payload, TT&C systems, and ground infrastructure.
• Support development of operational procedures, maintenance plans, configuration documentation, and sustainment processes.
• Provide technical oversight of anchor station reliability, redundancy, availability, and disaster recovery capabilities.
• Support cybersecurity implementation efforts for RF ground infrastructure, including protection of command and control pathways.
• Participate in customer technical reviews, design reviews, readiness reviews, and program milestone assessments.
• Mentor junior engineers and provide technical guidance across the RF ground engineering team.

Who You Are:

You are a highly experienced RF and satellite communications engineer with deep expertise designing, integrating, and operating mission-critical ground infrastructure supporting GEO communications systems.
