IT Infrastructure Specialist

About the role

This is a generalist role in a small IT team. The successful candidate will work across all four domains: core infrastructure, network & firewall, M365 & cloud, and cybersecurity. They will operate alongside managed service partners and be accountable for executing the infrastructure and security controls defined in Atalco’s NIST CSF framework and IT & Cybersecurity Strategic Plan.

Responsibilities

• Hands-on technical owner of Atalco’s server, virtualization, network, and cloud platforms across Gramercy, Louisiana and St. Ann, Jamaica.
• Core infrastructure: Windows Server, Active Directory, VMware vSphere, and the in-flight Nutanix hyperconverged migration, Veeam backup and restore testing, server lifecycle and licensing.
• Network & firewall: Cisco Catalyst switching and VLAN design, Meraki MX firewalls, dual-carrier WAN, site-to-site VPN between plants, wireless, and network documentation.
• M365 & cloud: Microsoft 365 tenant administration, Entra ID identity lifecycle and hybrid sync, MFA and conditional access, Intune, and Azure-hosted workloads.
• Cybersecurity: MTSA cybersecurity support under 33 CFR Part 101, vulnerability and EDR management.

Qualifications

• Education: Bachelor’s degree in IT, Computer Science, Information Systems, or related field. An associate degree plus two additional years of relevant experience, with a qualifying certification, may substitute.
• Experience: Minimum five (5) years hands-on infrastructure administration in production, with demonstrated ownership of servers, virtualization, and networking — not ticket handling alone. Multi-site support experience required, including one site supported remotely. Manufacturing, industrial, energy, or other 24/7 operating environment strongly preferred.
• Skills: All requirements in this section must be met to advance to interview. Required capabilities include Windows Server, Active Directory, VMware vSphere, Nutanix, Veeam, Cisco IOS, Meraki, Microsoft 365, Entra ID, Intune, Azure, MTSA, and cybersecurity practices.

Skills

• Windows Server: Install, harden, patch, and troubleshoot Windows Server 2016–2022; PowerShell for routine administration and reporting.
• Active Directory: AD DS administration, replication troubleshooting, Group Policy design, DNS and DHCP.
• Virtualization: VMware vSphere/vCenter host and cluster management, vMotion, resource allocation, patching.
• Nutanix: Hyperconverged platform management.
• Backup & recovery: Enterprise backup administration (Veeam preferred): job design, replication, immutable/offsite copies, and performing documented restores.
• Networking: Cisco IOS switch configuration, VLANs, trunking, spanning tree, routing fundamentals, and structured troubleshooting from the physical layer up.
• Firewall & VPN: Firewall rule administration and site-to-site VPN on a commercial NGFW platform; Cisco Meraki is a direct match.
• M365 Tenant administration: Microsoft 365 Tenant administration across Exchange Online, SharePoint, OneDrive, and Teams via admin centers and PowerShell.
• Identity & endpoint: Entra ID administration, hybrid directory sync, MFA and conditional access; endpoint management via Intune or equivalent MDM.
• Cybersecurity: Applied patch and vulnerability management, EDR, least privilege, and network segmentation; familiarity with NIST CSF, CIS Controls, or ISO 27001.
• Documentation: Produces network diagrams, runbooks, and change records that withstand audit review; prepared to show a redacted sample.
