About the role
• Aubrant Digital is seeking a Senior Systems Engineer, Windows, to own the Windows Server platform in a large US-based client data center supporting a 2,000+ virtual server environment (Windows and Linux). You will own patch content and standards in Tanium and run the monthly OS patch cycle with the Infrastructure Administrators; harden Windows servers; build VMs and maintain golden images, moving build templates and post-build configuration into code; plan and run the Windows Server 2025 upgrade with application owners; lead complex work in US overnight change windows such as upgrade steps and migration cutovers; and script patch pre-checks, post-patch validation, and reporting in PowerShell. Windows carries most of the manual work in this estate, so automation is a large part of the role. You will join Aubrant's cloud and infrastructure engineering group (we call it a studio), which gives you a technical leader to escalate to, peers on other engagements to call on, and a shared catalog of scripts and hardened builds to start from. Must-Have Requirements
• 7+ years administering Windows Server in enterprise data centers.
• Enterprise patch management for Windows servers, including pre-checks, validation, and rollback.
• Windows Server security is hardening.
• Active Directory and Group Policy as they apply to server builds and hardening (the client's identity team owns the directory).
• VM builds VMware vSphere, golden images, and templates.
• Windows Server OS upgrades or migrations with application owners.
• PowerShell scripting,



with changes kept in a Git repository (the client uses GitHub).
• Networking fundamentals (server IP addressing, subnets, firewall rules) and the ability to explain a needed network change to the network team.
• Ability to triage and resolve tickets and alerts independently through incident, change, and problem management, escalating only when needed.
• Willingness to work a shift that covers US overnight maintenance windows (shift hours and on-call participation to be confirmed).
• Professional written and spoken English; clear written handoffs and regular calls with a US-based client team. Should-Have Requirements
• Tanium patch management.
• Azure IaaS (the client uses Azure for off-site backup and expects to move more workloads there).
• Working knowledge of storage and backup (Pure Storage, Rubrik).
• Familiarity with ServiceNow, Datadog, or Prometheus.
• Experience covering US overnight change windows with written handoffs to a US team. Could-Have / Nice-to-Have Requirements
• Chef or Ansible for Windows configuration.
• Relevant vendor certifications (not required; hands-on experience is valued over certificates). Ideal Candidate Traits:
• Curious, proactive, and collaborative.
• Robust communication and teamwork skills.
• Committed to delivering solutions together, not in competition.
• Works comfortably inside the client's incident, change, and problem management, keeps looking for the next thing to automate, and promotes a one-team culture.
