• Understanding of networking fundamentals (TCP/IP, DNS, HTTP/S) and common network protocols.
• Active TS/SCI security clearance is required.

Nice to have

• Prior experience supporting the Intelligence Community, or other federal CNO/cyber mission programs.
• Experience with exploit development, binary analysis, or vulnerability research.
• Familiarity with anti-virus/EDR evasion techniques, obfuscation, and anti-forensics methods.
• Familiarity with Agile/Scrum development methodologies and modern CI/CD tooling in classified environments.
• Experience with embedded systems, firmware, or mobile platform development (iOS/Android).
