Linux Systems Administrator

The Opportunity

Looking for a hands-on Linux Systems Administrator to join its engineering team supporting a live broadcast production environment in Centennial, Colorado.

The immediate focus is on addressing a significant volume of server cybersecurity vulnerabilities and remediation activity. Working closely with senior engineers, this person will take ownership of day-to-day server patching, remediation and validation across a complex production environment where stability and attention to detail are critical.

This is a hands-on engineering position, not an architecture or management role. The successful candidate will be comfortable working directly on Linux systems, following established procedures and taking ownership of assigned remediation work.

What You'll Do:

Perform hands-on patching and maintenance of production Linux servers, including controlled reboots and post-patch validation.

Review cybersecurity vulnerability tickets, understand the underlying issue and determine an appropriate remediation approach.

Troubleshoot Linux systems and applications and navigate a complex production networking environment.

Coordinate the shutdown, patching and reactivation of servers with senior engineering staff.

Maintain clear documentation of completed remediation and patching activity.

Support occasional Windows server patching and vendor application updates.

Work closely with senior engineers and the wider team to safely reduce the backlog of outstanding vulnerabilities.

What We're Looking For

The strongest candidates will have 4-7 years of hands-on systems/infrastructure experience, with a strong foundation in Linux administration.

Essential:

Strong Linux systems administration experience

Production server patching and maintenance

Experience understanding and remediating cybersecurity vulnerabilities

Ability to troubleshoot within complex networking environments

Experience working carefully within production environments

Strong communication and ability to follow established engineering procedures

Preferred:

Rocky Linux, CentOS or RHEL experience

AWS / EC2 exposure

Bash, Python or other scripting experience

Grafana, Splunk, Dynatrace or similar monitoring platforms

Experience supporting broadcast, media, streaming or other high-availability production environments

The Right Profile:

We're looking for someone who is still very hands-on technically - someone who is comfortable being the person actually logging into the server, applying the patch, rebooting the system, validating the application and documenting the outcome.

Given the live production environment, the ideal candidate is technically capable, methodical and understands the importance of making controlled changes. They should also be comfortable taking direction from senior engineers and working within established team procedures.
