Description

SAIC is seeking cleared IT Systems Engineer and Network Administrator to lead the deployment, configuration, and sustainment of secure, mission-critical infrastructure and communication systems for a new Navy C4I lab. This is a senior, hands-on role-not suited for junior or entry-level candidates-where you will work alongside a Government Lab Manager to build the lab from the ground up. The selected candidate will be relied upon for expert-level knowledge, sound engineering judgment, and independent execution in a highly visible, mission-critical environment.

You will design, implement, and manage a classified lab environment supporting Command and Control (C2), secure communications, and data exchange across tactical and enterprise networks. This role also involves integration with coalition partner systems to enhance joint interoperability and mission success.

Job Summary:

Work is primarily performed on site in San Diego, CA and has some hybrid remote flexibility. You must live in the local area to frequently come on site.

Responsibilities:

• Design, deploy, and manage secure LAN/WAN networks, routers, switches, firewalls, and encryption devices per DoD standards
• Configure Cisco ASA with Firepower Threat Defense (FTD) for perimeter security and intrusion prevention
• Manage Cisco Catalyst Edge Routers and deploy Cisco SD-WAN for WAN integration and SATCOM communications
• Provide Tier I-III support for end-user devices (thin/zero clients, laptops, collaboration systems) in a classified environment
• Configure and maintain C2 application servers (DNS, chat, email) and unified communications platforms
• Integrate, configure, and sustain coalition communication systems such as Link 16, Link 22, TTNT, MIDS-JTRS, and Mission Partner Environment (MPE) for joint and combined operations
• Support interoperability with systems like CENTRIXS, CJSMPT, and NATO Improved Link 11 (NILE) as required for mission objectives
• Implement and manage timing and synchronization devices to ensure network integrity
• Deploy and monitor next-gen encryption devices (e.g., TACLANE)
• Manage physical data center infrastructure-racks, PDUs, airflow, and remote KVM access
• Collaborate with cybersecurity teams to implement STIGs and maintain systems in continuous ATO compliance
• Develop comprehensive technical documentation, network diagrams, and system support guides
• Serve as a key point of contact with government stakeholders and coalition partners for lab buildout and operations
