• ACTIVE TS/SCI SECURITY CLEARANCE REQUIRED**

D2 Consulting is looking for a skilled Senior Firewall Engineer to join a high-impact team protecting mission-critical infrastructure. You'll work side-by-side with both corporate and government leadership — meaning your work gets noticed, and your voice matters.

What You'll Actually Be Doing

This isn't a \"maintain the status quo\" role. You'll be solving real security challenges at enterprise scale:

• Design & build state-of-the-art secure network architectures — from concept to implementation
• Protect the network by managing WAN, LAN, CAN, and remote security environments, handling incidents with speed and precision
• Own the security stack — firewalls, F5 load balancers, web/mail gateways, IDS platforms, and management tools
• Lead incident response — investigate, document, and drive corrective action when it matters most
• Shape security operations by developing SOPs that the broader team will rely on
• Stay ahead of threats by researching and evaluating emerging network security technologies
• Be the expert in the room — serve as a trusted liaison to contract leadership, customers, and government DAA stakeholders on security posture, policies, and procedures

What You Bring to the Team

Required Clearance & Certifications:

• Active TS/SCI clearance (must be current)
• Ability to pass a U.S. Government Polygraph (post-hire)
• DoD 8140.01 / 8570.01-M IAT Level II compliant certification (current)
• CSSP Infrastructure Support certification — or the drive to earn it within 120 days of starting

Experience:

• 5+ years in Network Security within large-scale enterprise or global environments
• BA/BS degree preferred — but strong hands-on experience can speak just as loudly. You can substitute a degree with 4 years of additional experience
• Firewalls: Palo Alto, Juniper, Cisco
• Routers/Switches: Juniper, Cisco
• IDS/Threat Tools: FireEye, F5 Load Balancer, Cisco FTD
• OS/Platforms: Unix, RHEL, Windows Enterprise AD, VMware

Why This Role?

You'll be part of a team that works on problems that actually matter — supporting government missions at the highest levels. If you're a network security professional who wants scope, challenge, and the chance to influence enterprise-wide security decisions, this is the place.

Additional Information

All your information will be kept confidential according to EEO guidelines.
