Global Network Engineer - Classified Systems

Science Applications International Corp.; Newington (VA); Sur place; USD 80 000 - 120 000; Plein temps

Résumé du poste

SAIC seeks a Network Engineer to engineer and operate a worldwide classified network supporting diplomatic posts. The role requires navigating time-zone challenges, securing routing, switching, and transport, and performing end-to-end fault resolution under operational pressure.

You will design changes with formal controls, assess site surveys, and ensure security policies are enforced. DoD 8140/8570 IAT II certification and Top Secret clearance are required.

Qualifications

• Bachelor’s degree in a technical discipline and five years of enterprise network engineering experience.
• Working knowledge of routing and switching fundamentals — BGP, OSPF, VLANs, and convergence behavior.
• Working knowledge of WAN: VPN and tunneling, QoS, circuit troubleshooting, and working with carriers.
• Firewall and network security experience, including ACL and policy design.
• The ability to read a packet capture and reason from it across layers.
• CCNP-level knowledge or equivalent demonstrated experience.
• DoD 8140 / 8570 IAT Level II certification (for example Security+ CE), current.
• Willingness to take on-call rotation, support off-hours maintenance windows aligned to overseas time zones, and travel occasionally in support of post work.

Responsabilités

• Engineer and operate securing routing, switching, and transport across a worldwide classified network, including the encrypted transport layer and the in-line network encryptors that protect it.
• Troubleshoot complex faults end to end — distinguishing circuit, transport, encryption, routing, and device causes — and restore service to posts under operational time pressure.
• Provide Tier II and Tier III escalation support for incidents the service desk cannot resolve, including an on-call rotation that covers every time zone the mission operates in.
• Design and implement network changes through formal configuration control, with the test, back-out plan, and post-change verification done before the window opens rather than improvised inside it.
• Engineer post network architectures, including site surveys, equipment refresh, bandwidth and capacity planning, and the design compromises that constrained circuits force.
• Implement access control to sensitive network devices, and hardening standards, and remediate scan and assessment findings within the accreditation timelines.
• Operate network monitoring, performance management, and configuration compliance tooling so that problems surface before a post reports them.
• Document designs, configurations, and runbooks to a standard that lets the next engineer sustain what you built without calling you.
