    Description
    **ACTIVE TS/SCI SECURITY CLEARANCE REQUIRED**
    D2 Consulting is looking for a skilled Network Security 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 / M IAT Level II compliant certification (current)
    • CSSP Infrastructure Support certification - or the drive to earn it within 120 days of starting
    Experience:
    • 2-8 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
    Tech You'll Work With:
    • 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.
    • Compensation is unique to each candidate and relative to the skills and experience they bring to the position. The salary range for this position is typically $130-140k. This does not guarantee a specific salary as compensation is based upon multiple factors such as education, experience, certifications, and other requirements, and may fall outside of the above-stated range.
    • Highlights of our benefits include Health/Dental/Vision, 401(k) match, Accrued PTO, STD/LTD/Life Insurance, Referral Bonuses, professional development reimbursement, and more
