This is a broad role in a small IT team: on any given day you may be patching a server, tracing a network drop in the manufacturing area, hardening a firewall rule, onboarding a new hire, and closing help desk tickets. You will work closely with the IT Manager on infrastructure projects while owning the operational routines that keep the business running., Systems Administration * Administer Windows Server environments, Active Directory, Group Policy, DNS, DHCP, and file/print services. * Administer Microsoft 365 / Entra ID: user and license provisioning, Exchange Online, SharePoint, OneDrive, and Teams. * Maintain virtualization hosts and guests (Scale and/or Hyper-V), including resource monitoring, capacity planning input, and VM lifecycle. * Own backup and recovery operations: verify job completion, perform restore testing, and support disaster recovery and business continuity planning. * Manage patching and update cycles for servers, workstations, and applications; schedule and execute maintenance windows with minimal production impact. * Provide infrastructure support for line-of-business systems, including ERP/MRP, engineering and CAD/CAM applications, and shop-floor and quality systems (coordinating with vendors and application owners as needed). * Monitor system health, respond to alerts, and investigate performance issues before they become outages. Networking * Support and maintain LAN/WLAN and WAN infrastructure: switches, routers, firewalls, VPN, wireless access points, and structured cabling across office, manufacturing, and warehouse areas. * Configure VLANs, DHCP scopes, port assignments, and QoS; troubleshoot connectivity issues end to end, from the wall jack to the cloud. * Support site-to-site and remote-user VPN connectivity for satellite technical centers and traveling staff. * Maintain accurate network documentation, IP schemes, and rack/cabling diagrams. * Coordinate with ISPs, telecom, and low-voltage vendors on circuits, installs, and outages. Security * Administer endpoint protection/EDR, email security and filtering, and multi-factor authentication. * Apply least-privilege principles to accounts, shares, and administrative access; conduct periodic access reviews. * Support vulnerability management: run and interpret scans, prioritize remediation, and verify fixes. * Assist with security awareness training, phishing simulations, and incident response - containment, investigation support, and documentation. * Help maintain IT policies, standards, and evidence for customer, quality, or cyber-insurance audits. End-User Support & IT Operations * Serve as an escalation point for help desk tickets; resolve hardware, software, account, printing, mobile device, and A/V issues for employees on-site and remote. * Image, deploy, and maintain laptops, desktops, industrial PCs, mobile devices, scanners, and printers. * Execute onboarding and offboarding: accounts, equipment, permissions, and clean termination of access. * Support conference room technology and remote-meeting infrastructure. * Maintain the IT asset inventory and software license records. Documentation & Projects * Write and maintain runbooks, configuration standards, and knowledge base articles so procedures are repeatable and not dependent on one person. * Contribute to infrastructure projects: hardware refreshes, migrations, upgrades, and new-site or new-system rollouts. * Evaluate tools and make practical recommendations, including cost and effort estimates, to the IT Manager. ## 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 makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [An Applied Introduction to eBPF with Go](https://www.wearedevelopers.com/videos/1075-an-applied-introduction-to-ebpf-with-go) - [WebAssembly: The Next Frontier of Cloud Computing](https://www.wearedevelopers.com/videos/972-webassembly-the-next-frontier-of-cloud-computing) - [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) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) ## 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) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Best Paying Jobs in Technology](https://www.wearedevelopers.com/magazine/256-best-paying-jobs-in-technology) - [System change: restart as developer?](https://www.wearedevelopers.com/magazine/39-system-change-restart-as-developer) - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries)
