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 DevOps mindset to network operations (NetDevOps), 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., * Develop, maintain, and optimize our monitoring and observability infrastructure - including monitoring, logging, and tracing capabilities - to ensure high availability, scalability, and security * Design and build automation to streamline deployment, configuration, monitoring, and incident response, reducing manual effort and improving consistency across the environment * Apply DevOps practices to network operations - including version control, infrastructure-as-code, CI/CD pipelines, and automated testing and validation - to deliver changes faster and more reliably * Manage network configurations and automation code in source control, with peer review, change tracking, and repeatable, auditable deployment workflows * Build and maintain security monitoring, alerting, and telemetry that improve threat visibility, support detection and response, and feed security operations and incident response workflows * Automate security-related tasks such as configuration compliance, firewall and access policy validation, device hardening, and patch and firmware remediation to enforce cybersecurity standards at scale * Apply AI-based technologies and analytics to improve anomaly detection, event correlation, root cause analysis, and predictive network operations * Serve as a hands-on technical resource for complex configuration, troubleshooting, and escalation activities in production environments * Execute automation and observability initiatives end to end - scoping, scheduling, tracking milestones, and delivering on commitment dates * Partner with Cyber Security and plant engineering teams on secure network operations, including visibility and segmentation between IT and operational technology (OT) environments * Support network security operations by providing the monitoring data, automation, and integrations needed for firewall, NAC, VPN, and segmentation technologies * Continuously research, evaluate, and recommend new automation, DevOps, observability, security, and AI-driven tools and technologies that improve the reliability, security, and supportability of the network environment * Report project status, risks, and operational and security metrics to leadership on a regular cadence * Support a 24x7x365 fast-paced operational environment, including participation in on-call escalation * Travel to other Cleveland-Cliffs locations as required (approximately 10%) * Perform other duties as assigned; responsibilities may evolve with business needs, technical developments, or operational requirements ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Creating a routing app with Google Maps API from scratch](https://www.wearedevelopers.com/videos/831-creating-a-routing-app-with-google-maps-api-from-scratch) - [Your Infrastructure Is Not a Playground: AI Agents for Infra Done Right](https://www.wearedevelopers.com/videos/2084-your-infrastructure-is-not-a-playground-ai-agents-for-infra-done-right) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) - [Computer Vision from the Edge to the Cloud done easy](https://www.wearedevelopers.com/videos/263-computer-vision-from-the-edge-to-the-cloud-done-easy) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence) - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Best Paying Jobs in Technology](https://www.wearedevelopers.com/magazine/256-best-paying-jobs-in-technology) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Events like RSAC Get You CISOs.
