About The Position

Senior IT Network Administrator - Madison, WI
Full-Time | Global Engineering Environment | Travel Opportunities
At Baird, you’re not just maintaining systems, you’re building the backbone of a global organization.
If you’re someone who enjoys owning infrastructure end-to-end, solving complex technical challenges, and shaping how systems evolve, just maintaining them—this Senior Network Admin role is designed for you.
We’re a growing international coastal engineering consulting firm with teams and projects around the world. Our work depends on fast, secure, and reliable technology and that’s where you come in.
You’ll take the lead on our global IT environment, balancing hands-on technical work with forward-looking strategy.
Own and evolve our infrastructure
You’ll manage a hybrid environment across on-prem and cloud systems—Windows Server, Linux (RHEL/CentOS/Ubuntu), Active Directory, Microsoft 365 (Exchange, Teams, Entra), and more. You’ll also oversee virtualization (VMware/Hyper-V), storage, backups, and disaster recovery.
Support high-performance technical teams
Our engineers and scientists rely on powerful computing environments. You’ll help optimize systems, software, and workstations to keep their work running efficiently across both Windows and Linux platforms.
Design and manage networks that just work
You’ll build and maintain secure, reliable networks across offices and remote project sites—LAN/WAN, VPNs, firewalls, and wireless. When issues arise, you’ll troubleshoot quickly and implement long-term solutions.
Lead cybersecurity and compliance efforts
You’ll take ownership of our CMMC 2.0 readiness and alignment with NIST SP 800-171, helping assess gaps, implement controls, and support audits. You’ll be the go-to resource for keeping our environment secure and compliant.
Shape what’s next
You won’t just maintain what exists, you’ll help define what comes next. From new office setups to evaluating cloud and network technologies (SD-WAN, VPLS), you’ll play a key role in scaling our infrastructure.
Support people, not just systems
You’ll provide Tier 2/3 support, help users solve complex issues, and create documentation and processes that make everyone more effective.
