Position Overview
- Seeking a Senior Linux Administrator for an on-site contract engagement.
- This role operates, maintains, and secures RedHat, Ubuntu and other Linux systems running both on-prem and in Azure across both Commercial/GCC and Azure Government environments.
- This role sits at the intersection of Linux administration and Azure operations.
- Candidates should be equally comfortable at a Linux shell and working within AzureDevOps, Azure-native security tooling, and containerized workloads.
Key Responsibilities
- System Administration & Maintenance: Administer, configure, troubleshoot, and maintain production and non-production RHEL and Ubuntu Server VMs and physical servers.
- Security Hardening & Compliance: Maintain CIS-aligned hardening on Ubuntu systems, working within the agency's existing security stack, including Azure-native tooling such as Defender for Cloud and Azure Policy.
- Support compliance reporting and remediation using this stack.
- Patching & Lifecycle: Manage patching through Ubuntu Pro (Livepatch and Extended Security Maintenance) and APT, minimizing manual patch orchestration and unplanned downtime.
- Automation & Scripting: Write and maintain automation in Bash and PowerShell to support a mixed Linux and Azure environment.
- Familiarity with implementing Cron jobs and other scheduled automations.
- Azure & DevOps Integration: Familiarity and experience with on-prem Azure DevOps for source control, pipelines, and CI/CD supporting Docker configuration and deployment to a Linux environment.
- Containers & Secrets Management: Support Docker workloads running on standalone Linux VMs (outside of Kubernetes or Azure Container Instance clusters), including integrating containers with Azure Key Vault.
- Experience with using Azure Container Registry, including Push/Pull and vulnerability scanning.
- Identity & Access Management: Maintain and secure SSSD-based identity integration, including sudoers governance and PAM configuration.
- Storage & Filesystem Management: Manage LVM, filesystems (XFS/EXT4), and partition layout, including dedicated mounts such AS /VAR, /TMP, and /var/log/audit, in line with CIS guidance.
- Audit Support: Collaborate with the cybersecurity team to support audit findings, logging through auditd, and ongoing security posture, using the existing security stack and Azure-native tooling as the primary audit trail.
Required Qualifications & Technical Skills
- 8+ years of hands-on Linux administration in enterprise or government environments, with deep expertise in current Ubuntu Server LTS releases.
- Working knowledge of Azure as an operating environment for Linux VMs, including networking, managed identity, and Key Vault integration.
- Experience with Azure DevOps, including pipelines, repositories, and CI/CD workflows involving Linux systems.
- Experience with Docker on Linux, including secrets management approaches for containers running outside of managed clusters.
- Advanced Bash scripting and working PowerShell proficiency for cross-platform automation.
- Understanding of UFW, SSH hardening, AppArmor, and SSL/TLS certificate management.
- Proficiency with SYSTEMD, kernel tuning via /etc/SYSCTL.CONF, PAM, AUDITD, and log rotation.
- Ability to work independently with limited dedicated Linux peer support, as part of a small, cross-functional IT and security team.
Preferred Qualifications
- Certifications: Canonical/Ubuntu certifications, CISSP, or CompTIA Security+.
- AZ-900 and/or AZ-104 preferred.
- Healthcare or public sector experience, including state agency IT environments, MARS-E, HIPAA technical safeguards, or CMS security requirements.
- Experience supporting development infrastructure with fast-changing workload requirements.
