The BIS Infrastructure department at Argonne National Laboratory has an opportunity for a junior to mid-level Network Engineer within the Enterprise Network Infrastructure group at its Lemont, IL campus. The Networking team is responsible for designing, installing, operating, and troubleshooting the high-speed network infrastructure for the laboratory. This includes local area (LAN), wide area (WAN), wireless networks, datacenter networks, and security devices that provide firewall and VPN capabilities. Due to the nature of the work, the position will require primarily an onsite presence, with some remote work flexibility, and requires occasional off-hours work to minimize interrupting normal operations.
