About RapidFort
RapidFort helps enterprises and government organizations reduce software supply chain risk through hardened container images, runtime-based attack surface reduction, and automated vulnerability remediation.
We own and operate infrastructure that supports our engineering teams and core systems. We’re hiring an experienced Linux systems administrator to keep that environment secure, reliable, and running efficiently.
The Role
We’re looking for a technically sharp, hands-on Linux administrator who investigates problems thoroughly, takes ownership, and delivers lasting solutions.
You will administer production Linux systems, troubleshoot complex issues, write automation, and improve day-to-day operations. You should be comfortable moving from an unfamiliar symptom to a diagnosis, implementing a controlled fix, and verifying that the underlying problem is resolved.
This is a senior individual contributor role with direct responsibility for technical execution. Strong Bash scripting, practical Python skills, and deep Linux troubleshooting experience are essential. You will work closely with our infrastructure engineers while independently owning assigned systems, incidents, and improvements.
The position is remote within the United States. Physical data center experience is beneficial but is not required.
