CACI International is an American technology company founded in 1962 that works almost entirely for United States defence, intelligence and federal civilian agencies. It has moved from being a conventional IT services contractor toward supplying its own technology, with a substantial expeditionary electronic warfare and signals intelligence product line, photonics and optical communications for space, and secure network modernisation. Headquartered in Reston, Virginia, the company employs more than twenty thousand people, the majority holding security clearances, and has grown through a steady programme of acquisitions that add differentiated technology rather than headcount alone.

  • Develop system architectures, interface definitions, block diagrams, network diagrams, RF signal-flow diagrams, bills of material, configuration baselines, and technical operating procedures.
  • Design and integrate deployable SATCOM systems incorporating antennas, feeds, low-noise block downconverters (LNBs), block upconverters (BUCs), amplifiers, modems, waveguides, RF cabling, networking equipment, compute platforms, and mission-processing equipment.
  • Travel to operational, test, exercise, customer, vendor, and field locations to install, configure, operate, test, troubleshoot, maintain, and recover SATCOM prototype systems.
  • Create and maintain operator manuals, installation guides, troubleshooting guides, maintenance procedures, quick-reference cards, and training materials.

  • Ability to develop and interpret system architecture diagrams, RF block diagrams, network diagrams, wiring/cabling diagrams, interface-control documents, and technical procedures.
  • Experience with field installation, setup, operation, troubleshooting, and repair of communications or technical systems.
  • Working knowledge of IP networking, including routing, switching, VLANs, firewalls, addressing, throughput, latency, and network troubleshooting.
  • Ability to travel regularly and perform field work, including lifting and moving equipment, working outdoors, working from ladders or elevated platforms as required, and operating in austere or time-constrained environments.

Desired:

  • Experience with SATCOM systems operating in X-, Ku-, Ka-, C-, L-, or S-band environments.
  • Experience with commercial and/or military SATCOM terminals, hub systems, modems, and satellite network management tools.
  • Familiarity with RF test equipment such as spectrum analyzers, power meters, frequency counters, cable analyzers, and signal generators.
