Frontline Support: Interface directly with users of fielded systems to capture feedback, assist with technical support, and translate operational needs into software requirements.

Project Execution: Manage multiple tasks concurrently, meeting critical deadlines through self-directed planning, tracking, and reporting.


Advanced Range Systems & Cybersecurity


Real-Time Systems: Develop and modify software that provides real-time control of external devices (radar systems, target tracking, communication channels) and real-time graphical presentations of range operations.

Simulations & Modeling: Support the delivery of simulations, software models, and prototypes for targets and multi-spectral threat systems (RF, UV, IR, EO) for Air Combat Training Systems (ACTS).

Secure Development: Ensure all products meet strict DoD cybersecurity standards. Utilize static code analysis and support vulnerability assessments and penetration testing to provide technical evidence of software security
