Infrastructure Administrator

You will help lead the infrastructure layer of a growing, multi-site logistics business. The work spans cloud and on-premises systems, identity, networks, backup and recovery, monitoring, and security controls. You will work closely with the IT Systems Manager and operations, development, data, and cybersecurity teams.

WHY THIS ROLE MATTERS:

When infrastructure is unstable, every other technology initiative becomes noise. Your work will create the reliability and capacity the business needs to serve customers, support our agents, and grow and integrate new locations without adding unnecessary complexity.

What you will own:

• Designing and improving hybrid infrastructure standards across XGS sites and future acquisitions.
• Capacity, availability, and performance planning that identifies risk before it becomes an outage.
• Backup, disaster recovery, and recovery testing that prove systems can be restored, not merely that jobs completed.
• Business-aware monitoring and alerting, with actionable thresholds, accountable owners, and usable runbooks.
• Modernization and migration playbooks for a mixed environment that includes Microsoft 365, Azure, Entra ID, Windows, Linux, networking, IBM i (AS/400), and legacy platforms.

What success looks like:

Critical systems are available and scalable. Recovery targets are proven through testing. Single points of failure and noisy alerts are being removed, not documented and ignored. Infrastructure decisions, dependencies, and configurations are clear enough that the business is not dependent on one person., * You simplify and standardize instead of adding another tool, exception, or workaround.

• You bring options, trade-offs, and a recommendation that connects technology decisions to business impact.
• You document operating decisions, prioritize business value and risk, and reduce key-person risk through shared knowledge.

You have practical experience operating and improving a business-critical infrastructure environment. You make technical trade-offs, explain them in business terms, and stay calm when an incident demands clear decisions.
