Virtualization / Automation Engineer (Senior)

About the role

Computer World Services, Corp. (CWS) seeks a Senior Virtualization / Automation Engineer to design, operate, secure, automate, and modernize the virtualization and Software-Defined Data Center (SDDC) platforms supporting the USMEPCOM ENLIST program, including VMware vSphere, ESXi, vCenter, vSAN, NSX, Site Recovery Manager (SRM), and associated Infrastructure as Code capabilities.

The role owns the hypervisor and SDDC platform layers across production, development, test, COOP, disaster-recovery, and hybrid-hosting environments; guest operating systems, applications, databases, and cloud workloads remain with their respective teams. The engineer also supports the transition of applicable services to centralized DISA-hosting platforms through discovery, migration planning, migration support, validation, and stabilization.

Key Tasks & Responsibilities - Serve as senior engineering owner for the SDDC platform, establishing architecture, configuration standards, operational procedures, and engineering roadmaps.

- Build, configure, and optimize virtualization clusters, including vSphere HA, DRS, resource pools, hosts, datastores, and distributed switches, and manage ESXi and vCenter patching, upgrades, and certificates.

- Monitor platform capacity, availability, performance, and compliance, and recommend scaling, balancing, or remediation actions.

- Engineer vSAN clusters, storage policies, and fault domains, and troubleshoot vSAN performance, resynchronization, and policy-compliance issues.

- Engineer NSX segments, transport zones, gateways, routing, and distributed security controls, coordinating changes with network and cybersecurity teams.

- Administer SRM protection groups and recovery plans, develop and maintain automated failover and failback procedures, and support quarterly COOP exercises and continuity events.

- Design and implement infrastructure automation using Terraform, Ansible, PowerCLI, or APIs, with version control, peer review, testing, rollback, secrets protection, and drift detection.

- Coordinate with workload owners on resource requirements, placement, templates, and snapshots, preserving the division between platform and workload ownership.

- Provide Tier 4 engineering support for cross-platform incidents, isolate platform faults during outages, and conduct root-cause analyses and develop corrective actions.

- Maintain platform configuration backups, apply DISA STIGs and security baselines, and support RMF evidence, vulnerability remediation, and vendor-advisory reviews.

- Support technology refreshes and modernization; develop platform roadmaps, technical options, and rough-order cost estimates.

- Support DISA-hosting transitions through discovery, dependency documentation, readiness assessment, migration waves, test and rollback plans, cutover, and post-migration stabilization.

- Maintain architecture diagrams, as-built documentation, SOPs, and recovery procedures, and provide platform metrics and modernization status for program reporting.
