Job description

The IT Manager is the primary IT resource for our client and its jobsites, and also supports Mission Critical employees at other locations. The position has no direct reports and requires approximately 30% travel.

This is the only IT position based in that office, but it is not a solo assignment. The IT Manager is part of our client's broader IT team and is supported by it day to day. Within that structure, the IT Manager handles most of what comes up on site, which is why the role calls for a systems engineering or network administration background rather than a help desk background.

Team and Support Structure

• Part of client's larger IT team, with regular contact built into the job. The IT Manager also assists Mission Critical employees at other locations.
• Corporate IT owns the enterprise network, the Microsoft 365 tenant, and company wide standards, so this role never carries that layer alone.
• The wider IT group is available for troubleshooting, second opinions, and shared escalation, and client sends additional IT staff onsite when a job needs more people, including large projects, office moves, and jobsite mobilizations. No one is expected to solve everything alone.

Responsibilities

• Set up and configure job trailer networks at active jobsites, including internet service coordination, routers, switches, wireless access points, and VPN connectivity back to corporate.
• Own, maintain, and troubleshoot all onsite network equipment in the Dallas Mission Critical office and at jobsites, including switches, routers, wireless access points, cabling, and VoIP handsets. Escalate enterprise network and WAN matters to corporate IT.
• Decommission jobsite network equipment at project close out and return it to inventory.
• Deploy, configure, and maintain employee computers running Windows 11 and Mac OS.
• Support wireless iOS devices including iPhones and iPads, plus MiFi units and cellular hotspots.
• Install, configure, and troubleshoot printers, copiers, plotters, and related peripherals.
• Administer Active Directory and Microsoft 365 accounts for onboarding, access changes, and terminations, including equipment recovery.
• Manage tickets from intake through resolution, and escalated to corporate IT with clear diagnostic detail.
• Own IT inventory for the Dallas Mission Critical office and all associated jobsites, tracking equipment issued, in stock, in transit, and deployed in the field.
• Handle purchase requests, receiving, deployment, refresh, and secure disposal, and coordinate with vendors and resellers on quotes, orders, and delivery.
• Track software license and subscription assignments, coordinating renewals through corporate IT.
• Lead local IT projects including office moves, hardware refreshes, and jobsite mobilization and close out.
• Keep endpoints compliant with corporate security standards for patching, antivirus and EDR, multifactor authentication, and disk encryption.
• Deliver IT orientation to new Mission Critical employees, and maintain site documentation, network diagrams, asset records, and user guides.

Technical Requirements

• Network setup and troubleshooting: routers, switches, wireless access points, cabling, VPN, DNS, DHCP, and general TCP/IP. Able to stand up a working network at a remote site.
• Windows 11 and Mac OS administration, Windows Server fundamentals, and iOS device management for iPhones and iPads including mobile and cellular connectivity.
• Microsoft 365 administration at the site level, along with Active Directory and AD Manager account administration. Tenant level configuration stays with corporate IT.
• Help desk ticketing platform experience. PowerShell scripting and Microsoft Copilot use within Microsoft 365 are both strongly preferred.

Qualifications

• Minimum 6 years of IT experience, including at least 2 years as the primary IT resource for a site, or in a systems engineer, network administrator, or IT lead role.
• Hands on network setup and troubleshooting experience. This role builds and repairs networks at jobsites, with team support available for larger efforts.
• Comfortable being the only IT person onsite while collaborating daily with a remote team. Experience supporting remote or field users is strongly preferred.
• Experience managing IT inventory, procurement, and vendor relationships.
• Valid driver's license required for jobsite travel.
• College degree in Information Technology, Computer Science, or a related field is a plus. High School Diploma or GED is acceptable with equivalent IT experience and certifications.
• Strong analytical, communication, and organizational skills, with the judgment to know what to resolve locally, what to escalated, and when to pull in help. Certifications are a plus: CompTIA A+, Network+, or Security+, Cisco CCNA, or Microsoft MD-102 or MS-102.

Work Environment and Physical Requirements

• Based in the Dallas Mission Critical office with a minimum of 3 days per week onsite, plus approximately 30% travel to jobsites and other Mission Critical locations.
• Regular work at active construction sites, including uneven terrain, outdoor conditions, and required PPE. Business casual in the office, site appropriate attire in the field.
• Occasional after hours or weekend work for maintenance, office moves, and jobsite mobilization.

Ability to lift up to 50 lbs, with occasional stooping, kneeling, and crawling for cable and equipment work, plus extended screen time and repetitive keyboard and mouse use.
