Job Description This position sits within the Infrastructure organization and reports through IT Operations. This team is looking for a highly autonomous Senior Network Engineer who can immediately step into a hands-on role supporting enterprise network infrastructure. The engineer will be responsible for maintaining and enhancing networking operations across 65 locations, including 20 office locations and 45 job sites, while partnering closely with Infrastructure, Security, and IT Operations teams. The ideal candidate will serve as a true hands-on technical resource, owning firewall administration, routing, switching, wireless networking, network monitoring, and network security initiatives. They will work primarily within a large on-premises environment that is gradually adopting cloud technologies and expanding its Azure footprint. Success in this role will require someone who can take initiative, influence technical direction, solve complex infrastructure challenges independently, and operate effectively with minimal supervision.

We are a company committed to creating diverse and inclusive environments where people can bring their full, authentic selves to work every day. We are an equal opportunity/affirmative action employer that believes everyone matters.
