About the role

AV is seeking a Senior Linux Systems Administrator to design, deploy, and maintain enterprise Linux infrastructure across on‐prem and multi-cloud environments. You will lead efforts on Oracle Linux, RHEL, and Ubuntu, manage Canonical Landscape, enforce MFA, and drive security hardening and automation. You will implement IaC with Ansible/Terraform, oversee virtualization/storage, and support Tier 3 escalation for engineering services in a fast-paced defense-focused setting.

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.
