Overview

Space and Propagation Engineering Officers design and implement over the air transport operations for Marine Air-Ground Task Force, combined and joint task force, and coalition communication networks. They integrate spectrum dependent systems, design secure and resilient transport architectures, analyze waveform capabilities, and develop electronic warfare concepts for electronic protection and electronic support.

Minimum clearance: Secret, often with SCI exposure

Core Skills

  • Resilient communications design for degraded environments
  • Military and commercial space communications integration
  • Waveform analysis and spectrum-dependent systems integration
  • Electronic protection and support operational planning

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Telecommunications Engineering Specialists

Designing over-the-air transport architectures and integrating spectrum-dependent systems transfers directly to planning and implementing telecommunications system changes.

How to prepare: Build a sample commercial telecommunications upgrade proposal that documents user requirements, an architecture diagram, and capacity and resilience tradeoffs.

What the civilian work involves
  • Consult with users, administrators, and engineers to identify business and technical requirements for proposed system modifications or technology purchases.
  • Implement system renovation projects in collaboration with technical staff, engineering consultants, installers, and vendors.
  • Assess existing facilities' needs for new or modified telecommunications systems.
Civilian tools and software (examples)
  • Microsoft Visio
  • Microsoft Excel

Computer Network Architects

Designing secure, resilient transport networks under bandwidth and connectivity constraints provides a foundation for civilian network architecture and network problem solving.

How to prepare: Build a routed-network lab using Border Gateway Protocol BGP and document how the design maintains connectivity during a transport-link failure.

What the civilian work involves
  • Develop disaster recovery plans.
  • Develop and implement solutions for network problems.
  • Coordinate network operations, maintenance, repairs, or upgrades.
Civilian tools and software (examples)
  • Border Gateway Protocol BGP
