This role focuses on maintaining availability, enforcing security policies, executing approved changes, and responding to incidents across a large, globally distributed environment. The environment supports 1,000+ sites and 100,000+ users, including datacenters, manufacturing plants, sales offices, and customer contact centers. Technologies include Cisco, Fortinet, Zscaler, Silver Peak SD WAN, Akamai Guardicore, Tufin, Forescout NAC, Microsoft Azure, Google GCP, and related security platforms. This is a hands-on operational role working closely with global IT operations teams, security partners, and managed service providers to ensure secure, stable, and compliant network services. How you will do it: Operational Support & Maintenance Operate and support enterprise Zero Trust platforms, primarily Forescout NAC and Infoblox DDI. Perform daily monitoring, health checks, and troubleshooting of network access control services, DNS, and DHCP. Manage network access exceptions, MAC address repository (MAR) whitelisting, and device compliance checks for corporate and BYOD/Guest networks. Data Analytics & Asset Management Leverage data analytics skills to analyze, correlate, and reconcile asset data across Forescout, Infoblox, Axonius, and ServiceNow CMDB. Assist in identifying, classifying, and managing the lifecycle of over 30,000 unmanaged, IoT, and OT devices across the global network.

Execute DNS/DHCP configuration changes and IPAM updates following formal change management processes. Automation & Continuous Improvement Identify opportunities to automate repetitive operational tasks (e.g., utilizing PowerApps/Power Automate to streamline MAC address approvals). Assist with operational runbooks, standard operating procedures, and knowledge documentation for L1/L2 support teams., Job Title: Network Security Engineer Location: Devens, MA (Remote work) Duration: 4+ Months Job Summary: Seeking a hands-on Network Security Engineer to support Zero Trust Net… + 7 days ago ## 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) - [What the Heck is Edge Computing Anyway?](https://www.wearedevelopers.com/videos/593-what-the-heck-is-edge-computing-anyway) - [An Applied Introduction to eBPF with Go](https://www.wearedevelopers.com/videos/1075-an-applied-introduction-to-ebpf-with-go) - [Cyber Sleuth: Finding Hidden Connections in Cyber Data](https://www.wearedevelopers.com/videos/893-cyber-sleuth-finding-hidden-connections-in-cyber-data) - [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) - [Turning Container security up to 11 with Capabilities](https://www.wearedevelopers.com/videos/718-turning-container-security-up-to-11-with-capabilities) ## Related Articles - [9 Ways to Make Money Hacking](https://www.wearedevelopers.com/magazine/333-9-ways-to-make-money-hacking) - [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) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Top 6 Hackathons for Developers in 2023](https://www.wearedevelopers.com/magazine/263-top-6-hackathons-for-developers-in-2023) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
