Network Architect
This position is no longer accepting applications(closed Jun 21, 2026).
The Planet Group has partnered with a Milwaukee, WI based company to locate a Sr. Network Engineer for a contract to hire role.
We're seeking a Senior Network Engineer who will take ownership of the organization's core network infrastructure, including switches, routers, firewalls, wireless networks, and secure connectivity solutions.
This role is ideal for a networking professional who enjoys balancing hands-on technical work with project leadership, infrastructure improvements, and mentoring less experienced team members.
The position will require five days a week onsite in Milwaukee to start but will eventually be a hybrid role with only two days a week onsite. As it is a contract-to-hire role, we can only accept candidates who do not require sponsorship of any kind either now or in the future.
