Design, build, and support VMware vSphere virtualized infrastructure from the ground up, including GPU‑accelerated compute environments
Manage networking infrastructure including switches, VPNs, firewalls, and secure communications
Troubleshoot hardware, software, and systems integration issues across lab and test environments
Work closely with engineering and software development teams to support project‑ and program‑level integration efforts
Maintain and support hybrid on‑prem/cloud connectivity (Entra ID / GCC High)
Support infrastructure for software development and AI/ML workloads, including GPU compute resources and job scheduling
Maintain secure infrastructure in accordance with CMMC compliance requirements
Support high‑performance/GPU compute infrastructure (e.g., SLURM‑based clusters) for ML training and development pipelines
Provide hands‑on systems administration across both Windows and Linux environments, including patching, backups, monitoring, and incident response
Write and maintain scripts to automate routine administration, monitoring, and deployment tasks
Required Qualifications
Active DoD security clearance (or clearance‑eligible)

Experience administering Linux servers in a production environment (Ubuntu, RHEL, Rocky Linux, or similar)

Practical knowledge of networking fundamentals: switching, VPNs, firewalls, and secure communications

Preferred Qualifications
