16h•$120,000 - $180,000•Onsite

About The Position

CHAOS Industries is hiring a Network Administrator to own the design, implementation, and day-to-day operation of our network infrastructure across classified and unclassified environments. This is a hands-on technical role at the core of our IT and security operations; you'll build, configure, and maintain routers, switches, firewalls, and wireless infrastructure, monitor network performance and availability, troubleshoot connectivity issues, and ensure our network remains resilient, secure, and mission-ready. You'll work closely with the ISSM, cybersecurity teams, and program security teams to support secure network architecture across a complex, multi-domain enterprise. You'll sit within the IT/Infrastructure Division, embedded alongside systems engineers, cybersecurity analysts, and program teams, operating as the subject matter expert when it comes to how our networks are built, how they perform, and how they stay online. Keeping the network running, secure, and scalable is the job, and it's foundational to everything else we do. From day one you'll own network infrastructure configuration, lead efforts to optimize performance and reduce downtime, and help build out the network architecture that supports operations across every segment of our enterprise. This role has full ownership of the network lifecycle: from design to deployment to ongoing maintenance and troubleshooting.
