RANGE POSITION DESCRIPTION

The primary purpose is to provide software development related to modeling and simulation systems that support developmental and operational test and evaluation (DT&E and OT&E) test programs. These systems consist of primarily of computer networks, and system integration laboratories (SIL), but could also involve hardware-in-the-loop (HITL) facilities integrating digital and analog processors, cockpit displays and controls, aircraft, weapons, environmental, and threat models, databases, and operational flight program software related to interactive man-in-the-loop battlespace environments.

  • Proficient in C++, Python, Linux or similar programming languages.
  • Knowledge and understanding of Windows, Linux and any related operating systems, SQL databases.
  • Knowledge with software modeling and simulation integrating one or more of the following: sensors, electronic warfare systems, communication links, databases, aircraft, threat models, databases and weapons systems.
  • Knowledge with integrating software and modeling environments consisting of digital and analog processors, cockpit displays and controls, mechanical and electrical interfaces and flight program software.
  • Knowledge with testing, deployment, configuration management and software sustainment.
  • Ability to program (various languages and protocols), integrate/manipulate models and generate computer networks for virtual, live, and constructive simulation of combat aircraft avionics, armament, or electronic warfare systems. (C++, LINUX, WINDOWS, QT SQL, etc)

The primary duties required are those necessary to provide technical expertise in the area of software development, integration of models, armament, sensor and electronic warfare systems for a complex integrated battlespace modeling and simulation environments consisting of digital & analog processors, cockpit displays & controls, mechanical & electrical interfaces, and operational flight program software. Integrate with civilian/military professionals engaged in software development, flight simulator development, engineering, operation, and maintenance.

The incumbent develops software and will support the verification and validation of software, models and data from avionics, sensor, Electronic Warfare and weapons r
