Information Systems Security Engineer

Second Front Systems is looking for a technically deep, mission-focused, security-first Information Systems Security Engineer to strengthen our cybersecurity and solutions architecture practice.

Operating at the boundary between engineering delivery and DoD authorization, you will be responsible for owning the security architecture and compliance engineering view of 2F's Game Warden platform and customer applications it hosts.
