Millennium is a DoD-contracted cybersecurity firm built around offensive and defensive operations, with 300+ staff split heavily toward senior security roles (8 of 17 current openings). The stack reflects dual concerns: adversarial tooling (Metasploit, Cobalt Strike, Burp Suite, Bloodhound) for red team work, plus enterprise infrastructure (VMware, NetApp, SAP, Oracle, Deltek) for customer deployments and program management. Active hiring acceleration in security and engineering, combined with projects spanning penetration testing, exploitation research, and cloud connectivity, suggests scaling existing contracts rather than platform pivots.
Millennium Corporation provides cybersecurity services to Department of Defense and federal civilian agencies since 2004. The company operates across red team operations (penetration testing, exploitation research), defensive cyber operations, software engineering, and technical engineering. Work spans customer network assessments, domain-specific tool development, enterprise network deployment, and cloud connectivity implementation. The organization manages acquisition programs and compliance frameworks alongside operational delivery, serving clients across defense and federal civilian markets.
Offensive tools (Metasploit, Cobalt Strike, Burp Suite, Bloodhound, Nessus, Nmap), systems administration (PowerShell, Bash, Ansible, Red Hat), enterprise platforms (VMware vSphere, NetApp, SAP, Oracle, Deltek Costpoint), and frameworks (MITRE ATT&CK, Kali Linux).
Headquarters in Arlington, Virginia. Current hiring is limited to the United States market.
