Senior Network Engineer

Location: Cleveland, OHCleveland-Cliffs is seeking a hands-on Senior IT Network Engineer to design, deploy, and maintain the enterprise network, with a strong emphasis on the automation and observability solutions that keep it reliable, secure, and supportable.

As a senior member of the team, the engineer serves as a technical leader and mentor and is curious about how emerging AI-based technologies can improve network operations and security. Success in this role is measured by execution: automation delivered, visibility improved, and incidents detected and resolved quickly.
