GPO, OU design, delegation models, Kerberos encryption policy, forest trust (or no-trust) architectures, and hands-on hygiene remediation * Azure infrastructure administration - IaaS resource management, hybrid identity and connectivity, Azure Backup, and day-to-day subscription operations * Experience with SCOM and SCCM administration at enterprise scale * NetApp ONTAP familiarity - storage provisioning, datastore management, and ONTAP integration with virtualization platforms * PowerShell scripting proficiency - able to write production-grade, maintainable scripts without supervision * Comfort operating within formal change management processes (CAB, RFC workflows) Preferred Experience * Hypervisor management and migration * Delinea Secret Server or comparable PAM platform administration * Entra ID / hybrid identity management alongside on-premises Active Directory * Freshservice or comparable ITSM platform experience * Experience using AI tools (Copilot, Claude, etc.) to accelerate documentation and runbook production ## Description vSphere Version Upgrades * Assess and upgrade legacy vSphere environments (currently running 6.7 and 7.0.3) across production vCenter environments covering ~560 VMs at Glenview HQ and Westmont colocation * Plan upgrade sequencing across ESXi hosts, vCenter Server, and dependent workloads (NetApp ONTAP, vSAN) - accounting for compatibility matrices and workload risk per site * Validate upgrade readiness, manage pre/post validation checklists, and produce runbooks for each site phase * Work within the CAB change management process - submitting RFCs, supporting approval workflows, and owning change execution windows VMware to Alternative Hypervisor Migration * Lead technical planning and phased execution of migrating workloads from VMware vSphere to an alternative hypervisor platform * Assess VM inventory, identify migration waves by workload criticality, and produce a detailed migration runbook * Validate storage integration (NetApp ONTAP) and network compatibility across migration targets * Identify and document platform-specific gaps (HA behavior, DRS equivalents, backup/snapshot integration, tooling changes) * Coordinate with storage and application teams to validate workloads post-migration * Produce clear before/after documentation suitable for handoff to permanent staff Active Directory Hygiene & Identity * Design, maintain, and remediate Active Directory across multiple untrusted forests - including GPO architecture, OU structure, security delegation, and encryption policy enforcement * Drive AD hygiene initiatives: stale object cleanup, OU rationalization, privileged account audits, and group membership reviews across ITW.COM and ITWCONNECT.NET * Evaluate authentication protocols, enforce encryption standards (AES Kerberos, RC4 remediation), and remediate misconfigurations before they become incidents * Operate identity and secrets infrastructure including Delinea Secret Server, service account lifecycle, and rotation automation across untrusted forests * Adopt and expand gMSA usage to reduce reliance on manually managed service account passwords SCOM & SCCM * Manage and evolve SCOM and SCCM across the environment - service account hygiene, gMSA migration, alert management, and agent health Server Infrastructure * Plan and execute server deployments end-to-end - from build templates and hardening scripts through rack, stack, and production handoff across both physical and virtual infrastructure * Administer VMware vSphere and Hyper-V platforms and NetApp ONTAP storage - VM provisioning, datastore management, and performance tuning for Windows workloads Azure Infrastructure Management * Manage Azure infrastructure - resource administration, subscription hygiene, tagging, cost awareness, and access control * Maintain hybrid connectivity between on-premises environments and Azure - ensuring consistent identity, DNS, and routing across the boundary * Administer Azure Backup - backup policy management, vault configuration, and recovery validation for both Azure-hosted and hybrid workloads * Support Azure infrastructure buildout for ongoing migration and modernization projects (SharePoint, server workloads) Automation & Tooling * Build and maintain PowerShell tooling for audit, remediation, and operational reporting - writing production-grade scripts that the team can maintain and extend Documentation & ITSM * Produce and maintain project runbooks - translating complex infrastructure work into clear, repeatable procedures that the broader team can follow * Manage infrastructure support tickets in Freshservice - owning incidents and requests from triage through resolution, with clear communication to stakeholders throughout, Join a dynamic team as a Software Engineer specializing in COBOL, where you will play a crucial role in enhancing high-quality training data for advanced AI systems.
