• Active or eligible SECRET security clearance (must be willing to obtain and maintain).
• Bachelor’s Degree in Cybersecurity, Computer Science, Information Systems, or related technical discipline; equivalent work experience considered.
• 5+ years of SOC/NSOC or cyber defense experience, with demonstrated IR and threat hunting expertise.
