MILSATCOM Mission Planner

Amentum is seeking a MILSATCOM Mission Planner to support critical Department of War strategic communications capabilities in the National Capital Region. This position directly supports the planning, integration, and employment of Advanced Extremely High Frequency (AEHF) satellite communications capabilities used by Combatant Commands, Joint Forces, and National-level decision makers. The selected candidate will be part of a highly skilled team responsible for ensuring secure, resilient communications supporting global military operations and strategic deterrence missions.

The ideal candidate brings operational experience from military communications, SATCOM, NC3, signal, communities and understands how strategic communications capabilities enable commanders to maintain assured communications in contested and degraded environments. Your expertise will help ensure America's most critical communications systems remain available, protected, and ready to support the warfighter whenever and wherever needed.

• Monday through Friday, standard business hours
• Full-time, on-site position in Northern Virginia
• Participation in an on-call rotation is required
• On-call support may require response outside of normal business hours to support operational requirements.

• Build, modify and maintain AEHF communications plans using the Mission Planning Subsystem (MPSS/MPE). Responsible for resource allocation, beam assignments, terminal access, and network configurations.
• Develop and maintain operational mission scenarios and communications plans and distribute them to operational crews to ensure accurate and timely implementation.
• Plan and deconflict Extended Data Rate (XDR) services across all modulations and modes to meet user priorities and throughput requirements.
• Manage spot beam allocations to support shifting operational priorities and theater demands.
• Responsible for crosslink planning and multi-satellite network configurations to ensure global connectivity without reliance on ground relays.
• Provide support to real-time requests for service, contingency operations, and anomaly resolution, rapidly re‑planning resources when conditions change.

• Build and maintain accurate terminal profiles and network membership data within the MPSS and MPE, ensuring each terminal's supported waveforms, data rates (LDR/MDR/XDR), and configuration parameters match what is fielded.
• Assess terminal RF characteristics, including antenna size and gain, EIRP, G/T, and pointing and tracking performance, and incorporate them into link budgets so plans reflect real-world terminal capability rather than nominal system values.
• Provide organizational support to operational personnel including but not limited to advanced troubleshooting, field and unit level removal and replacement, and terminal maintenance.
• Track terminal software and hardware baselines.
• Support terminal integration testing, operational readiness checks, and exercise activation, serving as the link between terminal program offices, unit operators, and satellite operations planners.
• Incorporate terminal fielding schedules, availability, and maintenance status into long‑range planning and CONOPS, identifying where terminal limitations, rather than space segment capacity, constrain operational capability.

• Understand link budget analyses accounting for EIRP, G/T, free‑space path loss, atmospheric and rain attenuation (particularly significant at EHF/SHF frequencies), pointing losses, and implementation margins.
• Assess link margins to determine whether proposed services will close under nominal, degraded, and contested conditions,…
