IT Systems Administrator

Position Overview

As an IT Systems Administrator, you’ll keep the Americas and Asia Pac side of our technology — Windows servers, Azure, Microsoft 365, and the network — patched, protected, and healthy, so small problems never get the chance to spread. And when something does break, you’ll fix it, find out why, and show the Service Desk how to handle it next time.

This role supports, maintains, and improves the enterprise infrastructure and systems platforms that serve global operations. This role resolves moderately complex technical problems independently, works within established architecture, standards, and priorities, and contributes to project delivery and continuous improvement. It escalates the most complex or architectural issues to senior engineers and develops toward greater technical depth and independence.

What You’ll Be Doing

1. Systems, Infrastructure, and Cloud Platform Operations

o Operate, configure, and maintain Windows/Linux servers, virtualization hosts, cloud workloads, Microsoft 365 services, and management tooling to keep infrastructure stable, supportable, secure, and reliable.

o Monitor infrastructure, cloud workload health, capacity, performance, platform alerts, and service health, and take action or escalate when thresholds, failures, or reliability risks are identified.

o Administer collaboration platforms, including Teams, SharePoint, OneDrive, Exchange Online, and supporting policies in partnership with Cybersecurity.

o Monitor and support Azure cloud resources, usage, tagging, lifecycle status, and operational health; identify and recommend opportunities to improve reliability, simplify administration, remove unused resources, and reduce unnecessary cost in alignment with approved cloud standards.

2. Network and Connectivity Operations

o Operate global LAN, WAN, Wi-Fi, internet, VPN, firewalls, and site-to-site remote access connectivity across offices, manufacturing, warehouse, and remote workforce locations.

o Monitor circuits, latency, packet loss, device health, wireless coverage, certificates, guest access, and connectivity issues, and coordinate restoration with carriers, vendors, and internal partners.

o Maintain DNS, DHCP, IP address management, scopes, reservations, zone records, and IP allocation standards.

3. Endpoint, Device, and Workplace Technology Operations

o Package, test, publish, retire, and troubleshoot business applications on endpoints, and deploy operating system and application patches while monitoring and remediating compliance failures.

4. Incident, Backup, and Operational Recovery Support

o Diagnose and resolve moderately complex, multi-step incidents escalated from the Service Desk, including infrastructure, network, endpoint, cloud, backup, and collaboration platform issues.

o Monitor backup jobs, agents, infrastructure integrations, restore readiness, and failures; remediate issues, coordinate operational follow-up, and escalate risk when needed.

o Identify and perform root-cause analysis on recurring issues and coordinate resolution with application owners, vendors, carriers, and senior engineers as appropriate.

5. Security, Risk, Compliance, and Lifecycle Maintenance

o Plan, test, deploy, validate, and remediate operating system, firmware, hypervisor, server platform, endpoint, and application updates according to established schedules and standards.

o Support access provisioning, licensing hygiene, encryption operations, vulnerability remediation, and control evidence activities in line with lifecycle, least-privilege, SOX, licensing, and audit requirements, as needed.

o Follow data classification and access best practices so AI tools and other systems do not expose sensitive information.

6. Data Center, Documentation, and Knowledge Management

o Operate and maintain data center and server room operations, including rack layout, power, cooling, cabling, remote hands coordination, and physical infrastructure checks.

o Maintain accurate support diagrams, runbooks, procedures, dependency maps, operational knowledge articles, inventories, asset records, ownership, location, lifecycle state, and configuration records.

o Document procedures, troubleshooting steps, known issues, and lessons learned to improve Service Desk handoffs, peer support, and operational consistency.

o Maintain infrastructure records, diagrams, configuration standards, dependencies, ownership, lifecycle status, and runbooks to support reliable, secure, and well-documented IT infrastructure operations.

7. Automation, Project, Change, and Partner Support

o Leverage approved AI technologies, automation tools, and scripting capabilities where appropriate to improve IT Operations, streamline existing processes, reduce manual effort, improve service quality and consistency, and enhance operational efficiency.

o Automate routine administration and provisioning tasks using approved scripts and tools, ensuring solutions are appropriately tested, documented, secure, supportable, and compliant with established standards. Validate any AI-generated code or configuration for accuracy and security before use.

o Deliver assigned technical tasks within infrastructure and systems projects, migrations, upgrades, and rollouts; follow change and release practices; document changes; and support handover to operations.

o Partner with Applications, Cybersecurity, Data & Analytics, business users, vendors, and support providers to understand needs, resolve issues, and recommend improvements to processes, tools, and runbooks.

What You’ll Bring to the Role

• 2+ years in IT, with hands-on infrastructure work — whether as a systems administrator or in a Service Desk role where you’re ready for the next step.
• Hands-on experience with Windows Server, Azure, Microsoft 365, and networking fundamentals (TCP/IP, DNS, DHCP, VLANs, switching, routing, firewalls). Experience with Linux, virtualization, endpoint management, backup, and monitoring tools is a plus.
• Experience working within ITIL/change management, security, and audit practices — and the judgment to know which calls are yours and which belong with senior engineers or Cybersecurity.
• PowerShell scripting — you can write a script from scratch and adapt someone else’s, and you know AI-generated code needs checking before it runs.
• A knack for explaining a technical problem to a non-technical colleague clearly and calmly — without making them feel like they caused it — and a habit of teaching what you know.
• Real curiosity: you want to know why something broke, and you’re comfortable that a lot of this job is the routine work that keeps everything running.
• Associate’s or Bachelor’s degree, or equivalent experience; technical certifications and ITIL certification are a plus.

About the Team

You’ll join a lean global infrastructure team spanning the Americas and EIMEA, where everyone gets broad exposure. Day to day, you’ll work alongside our Americas senior engineers — including a dedicated network engineer — who own architecture and the toughest escalations, and you’ll grow toward that depth yourself through vendor calls, global projects, and hands-on time with them. You’ll also partner with the Service Desk, Cybersecurity, Applications, and Data & Analytics teams, along with the vendors and carriers who keep our sites connected. It’s a team that values ownership: picking up the work in front of you, seeing it through, and leaving things better documented than you found them.
