What We Need From You (Required)

  • Active Top Secret clearance (U.S. Citizenship required)
  • 8–10 years of experience in software development and architecture using Microsoft .NET technologies (MVC)
  • Proven experience designing and leading enterprise‑scale application architectures
  • Strong understanding of object‑oriented design (OOD) and modern software engineering principles
  • Ability to collaborate with, influence, and communicate effectively across a diverse set of technical and mission stakeholders
  • Bachelor’s degree in Computer Science, Engineering, or a related field
