- 3+ years of hands-on experience in information systems, networking, or computer science, OR a Computer Science degree.
- Hands-on experience with physical network infrastructure — cabling, TAPs/SPAN ports, physical installation, and troubleshooting (not just conceptual understanding).
- Candidates should have a primary background in technical/systems support and network infrastructure. Applicants with exclusively cybersecurity experience and no hands-on server/network infrastructure administration will not be considered.
- Customer-facing technical support experience.
- A demonstrated pattern of self-directed technical learning — able to speak to a specific example from the
past year (personal project, home lab, certification pursued on your own initiative).
Additional Preferred Qualifications:
- Exposure to Bash scripting and Ansible (prior use is a plus — production automation ownership is not expected).
- Familiarity with virtualization and container platforms.
- Familiarity with RMF/STIG-adjacent concepts is a plus
