The Engineering Technician supports system deployment and installation, operational checkout, acceptance testing, fault isolation, repair and refurbishment validation, configuration verification, technical documentation, and customer training. The position interfaces directly with Engineering, Product Support, Government customers, operators, maintainers, OEMs, and vendor support organizations to maintain technical knowledge and resolve complex system problems.

The ideal candidate is an experienced SATCOM and systems integration professional capable of rapidly diagnosing and restoring mission-critical communications systems in CONUS and OCONUS environments, while also serving as a trusted technical advisor and instructor to Government customers and contractor teammates.

Responsibilities:

System Integration, Deployment & Operational Support

• Lead and support deployment, installation, integration, setup, and operational checkout of TIGS and related tactical or strategic communications systems.
• Support prototype integration, demonstrations, engineering evaluations, operational testing, and fielding activities.
• Integrate hardware, software, RF, networking, antenna, timing, power, and environmental-control subsystems into complete operational solutions.
• Provide responsive field engineering support to diagnose and restore mission-critical communications capability.
• Support, development and operational exercises, system recovery efforts, and other customer-directed technical activities.

Troubleshooting, Maintenance & Repair

• Diagnose complex system and component failures using electrical schematics, OEM technical manuals, engineering drawings, technical procedures, and system documentation.
• Perform fault isolation and root cause analysis across RF communications, signal distribution, networking, antenna, power, environmental-control, and timing subsystems.
• Perform corrective and preventive maintenance and support repair-versus-replace recommendations as required.
• Perform cable fabrication, connector repair, soldering, weatherization, continuity testing, and related hands‑on repair activities.
• Perform calibration support, sweep testing, inspection, and validation of RF cables, waveguide assemblies, and communications hardware.
• Coordinate with OEM and vendor technical support organizations to resolve technical problems and maintain current system knowledge.

RF, Electrical & Network Test

• Conduct RF performance verification and fault isolation using spectrum analyzers, network analyzers, signal generators, oscilloscopes, multimeters, network test equipment, and other RF/electrical test equipment.
• Verify signal paths, RF performance, network connectivity, timing, and subsystem interfaces against technical requirements and approved configurations.
• Support acceptance testing and post‑repair validation of SATCOM and integrated communications equipment.
• Document test results, discrepancies, corrective actions, and final system status.

Depot Sustainment & Configuration Validation

• Perform depot-level validation, troubleshooting, acceptance testing, and return-to-service verification following repair or refurbishment.
• Support system inspections, maintenance planning, configuration validation, and readiness assessments.
• Verify installed hardware, software, cabling, interfaces, and configuration status against approved technical baselines.
• Document maintenance actions, corrective actions, configuration status, and unresolved technical risks in established program systems and records.
• Support engineering change implementation, technology refresh, modification, and sustainment activities as directed.

Technical Documentation & Engineering Support

• Provide technical analysis and support for the design, development, integration, testing, documentation, implementation, and sustainment of hardware, software, and integrated product solutions.
• Author, review, and improve technical procedures, maintenance instructions, troubleshooting guides, test procedures, and training materials.
