The Principal RF Ground System & Anchor Station Engineer will serve as the technical authority responsible for the design, integration, test, deployment, and sustainment of the RF ground system and anchor station infrastructure supporting a major U.S. Government GEO satellite communications program. Operating within a Government‑Owned, Contractor‑Operated (GOCO) environment, this role will lead the technical execution of mission‑critical RF ground capabilities that enable secure, resilient, and high‑availability satellite communications services.

Working closely with the Ground Segment IPT Lead, spacecraft providers, network teams, cybersecurity organizations, and mission operators, the successful candidate will own RF architecture development, feeder link connectivity, TT&C implementation, and operational readiness across the full ground segment lifecycle. This position requires deep expertise in satellite communications systems, anchor station operations, and large‑scale RF infrastructure, along with the ability to translate mission requirements into practical engineering solutions that balance performance, availability, cost, and schedule.

• Serve as the principal technical authority for the RF Ground System and anchor station supporting GEO satellite communications operations.
• Lead engineering activities associated with the design, development, integration, and deployment of mission‑critical RF ground infrastructure, including:
  • Large aperture antenna systems
  • RF chains and associated subsystems
  • Frequency conversion equipment
  • High‑power amplification systems
  • Low‑noise receive systems
  • Modems and waveform processing systems
  • Monitoring and control systems
  • RF monitoring and spectrum management capabilities
• Develop and maintain RF ground segment architecture, requirements, interface control documents (ICDs), and technical baselines.
• Support the Ground Segment IPT Lead in coordinating technical execution across spacecraft, ground segment, network, cybersecurity, and operations teams.
• Lead engineering activities supporting satellite feeder link connectivity, including:
  • Link budget development and validation
  • RF performance analysis
  • Carrier planning
  • Spectrum coordination
  • Availability and resiliency assessments
  • End‑to‑end communications performance verification
• Provide technical leadership for TT&C ground system implementation, including command path design, telemetry reception, tracking support, and operational interfaces.
• Support development and execution of ground segment integration and test activities, including:
  • 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…
