• Active TS/SCI with Poly security clearance 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 including iOS/Android
• Ability to work independently and collaboratively within a small, mission-focused team under tight timelines
• Linux development experience

Base pay range $106,300–$206,200 USD for specified states (California, Colorado, Connecticut, Hawaii, Illinois, Maine, Maryland, Massachusetts, Minnesota, New Jersey, New York, Ohio, Vermont, Virginia, Washington, and District of Columbia). Compensation varies based on office location, role, skill set, and experience level. Benefits package available.
