Millennial Software is looking for a self-starting, team-oriented Mid-to-Senior Network Engineer to join our dynamic development and operations team in supporting a Government customer. The network engineer will own a medium-sized, multi-enclave network that spans several classification levels and rides across multiple commercial service providers, using VPNs and government-approved encryption to maintain end-to-end security. The environment is primarily Cisco and carries both development and operational data, so the successful candidate will be comfortable balancing fast iteration for development teams against the change discipline an operational mission requires.
