Proficiency in scripting languages such as Bash or Python.
Experience with enterprise virtualization platforms (VMware, KVM, Proxmox).
Hands‑on experience with monitoring tools such as Zabbix and familiarity with Nautobot or network source‑of‑truth systems.
Ability to communicate clearly with customers, gather requirements, and deliver tailored technical solutions.
Demonstrated ability to collaborate across functional teams in a fast‑paced environment.
Understanding of security/compliance frameworks (NIST 800‑171, STIGs, RMF) and CUI enclave operations.
Strong analytical and troubleshooting skills.
Ability to obtain a Top Secret clearance.
US Citizenship
Preferred Qualifications
Experience deploying and supporting GPU‑based compute systems in secure environments.
Familiarity with AI/ML workflows, containers (Docker, Podman, Singularity), or HPC environments.
Experience designing dashboards, alerting pipelines, or automation within Zabbix or Nautobot.
Experience with CI/CD automation for infrastructure.
Experience supporting multi‑tenant or cross‑domain architectures.
Linux certifications (RHCSA, RHCE, Linux+).
Security certifications (Security+, CISSP) depending on enclave requirements.
The Linux Systems Administrator will support and enhance a mixed enterprise environment consisting of approximately 400 Linux‑based endpoints distributed across multiple enclaves, including Controlled Unclassified Information (CUI) systems and dynamic research/development lab environments.
This role requires a balance of deep technical capability and strong customer engagement skills. The successful candidate will meet with internal customers to understand mission needs, translate those requirements into technical solutions, and deploy them efficiently. The administrator will help shape and automate new service offerings such as Virtual Machines as a Service (VMaaS), development environments on demand, and other compute provisioning workflows.
The role operates within a highly collaborative, cross‑functional environment that includes cybersecurity, networking, engineering, operations, and program teams. The administrator must be comfortable working independently, adapting quickly, and contributing to an innovation‑focused culture.
Key Responsibilities
Administer, monitor, secure, and troubleshoot enterprise Linux systems across ~400 endpoints in multiple enclaves.
Meet with internal customers to gather requirements, design solution paths, and implement systems rapidly and effectively.
Collaborate with cross‑functional teams to architect, deploy, and maintain new infrastructure services.
Develop and maintain automation using Ansible, Terraform, or similar tools to support provisioning, configuration management, and lifecycle operations.
Design and operate automated workflows supporting VMaaS and on‑demand development environments.
Create and maintain scripting solutions (Bash, Python, etc.) for system automation and operational improvements.
Configure and maintain enterprise monitoring and observability platforms (e.g., Zabbix, Nautobot).
Support secure deployment and operation of GPU‑enabled systems and AI/ML toolchains.
Maintain compliance with CUI and other secure enclave requirements, including patching, auditing, hardening, and security documentation.
Troubleshoot complex system issues across compute, storage, virtualization, and network layers.
Evaluate and propose emerging technologies to improve service delivery and operational efficiency.
