About the role

Set of X is hiring a Linux System Administrator to support our prime contract. This role requires TS/SCI clearance with polygraph, extensive RedHat/CentOS/UNIX experience, NiFi data flows familiarity, and virtualization handling (VMware ESXi, KVM). You will collaborate with current owners to understand systems, translate requirements into scalable, long‑term solutions, implement final architectures, and participate in strategy meetings while fostering strong customer relations.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
