nou Systems is seeking a Tier 2 IT Systems Support Specialist to join a small, hands-on IT team supporting five offices, remote employees, and a classified lab environment.

This is a good fit for someone who already has solid help desk experience, is comfortable on the Linux command line, and wants to keep growing into systems administration and DevOps-style work. We value curiosity and a willingness to learn as much as a long list of certifications.

• Write Bash (and ideally Python) scripts to automate routine tasks

• Support Linux virtual machines in VMware vSphere and AWS GovCloud

• Apply security hardening and compliance baselines (e.g., STIGs, CIS) in coordination with IT Security

Developer and Engineering Support

• Support engineers' development environments, toolchains, and licensed software

• Assist with administration of GitLab, including user access, runners, and CI/CD pipeline troubleshooting

• Help build and support containerized workloads (Docker) and related build workflows

• Troubleshoot certificate, proxy, and network issues that affect developer tools

Classified and Compliance Support

• Support systems in a classified lab (Open Storage Area) in accordance with security procedures

• Follow change management, asset tracking, and documentation requirements

• Support CMMC / NIST SP 800-171 compliance activities alongside IT and InfoSec

• Scripting experience in Bash, Python, or PowerShell

• Familiarity with Git and GitLab (or similar) and basic CI/CD concepts

• Experience with Docker or other container tools

• Exposure to VMware vSphere and/or AWS (GovCloud a plus)
