Senior Network Engineer

Location:

Cleveland, OH

Cleveland-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. Reporting to the IT Network Manager and working alongside a team of experienced Network and Network Security Engineers, this senior role is automation-first - treating manual, repetitive work as a problem to be solved through code, orchestration, and intelligent tooling.

The engineer brings a Dev Ops mindset to network operations (Net Dev Ops ), applying version control, infrastructure-as-code, CI/CD pipelines, and automated testing to how the network is built, changed, and validated. Security is embedded in the work: the engineer builds visibility and automation that strengthen the organization’s security posture and support rapid detection and response across corporate, mining, and steelmaking operations in a multi-site environment.

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. This position is critical in supporting the success of Cleveland-Cliffs and provides excellent opportunity for career growth and progression.
