A primary focus includes managing and scaling Canonical Landscape to administer hundreds of Ubuntu developer desktops within a strict CMMC 2.0 Level 2 / NIST SP 800-171 compliant environment. The ideal candidate brings deep expertise in Linux PAM architecture, enterprise MFA integrations, infrastructure-as-code automation, and defense-in-depth security hardening.

Position Responsibilities

• Developer Fleet Management: Architect, deploy, and administer Canonical Landscape to manage configuration profiles, package repositories, compliance policies, and automated patch management for hundreds of Ubuntu developer endpoints.
• Identity & Access Management (MFA/PAM): Implement and enforce robust authentication and authorization frameworks, including smart card/FIPS-compliant MFA at desktop and SSH login, PAM module engineering, SSSD/FreeIPA integration, Active Directory/LDAP bridging, and centralized sudoers delegation.
• CMMC L2 & Security Compliance: Harden Linux servers and workstations to NIST SP 800-171, DISA STIG, and CIS Level 2 benchmarks. Implement SELinux/AppArmor enforcement, auditd daemon logging, file integrity monitoring (FIM), and SIEM log forwarding.
• Automation & Configuration Management: Develop and maintain Infrastructure-as-Code (IaC) and configuration baselines using Ansible, Terraform, Puppet/Chef, and advanced Bash/Python scripting.
• Storage & Virtualization: Configure and troubleshoot enterprise SAN/NAS storage, iSCSI/NFS mounts, multipathing, LVM volumes, and VMware ESXi/vCenter virtualization for Linux guests.
• Engineering Tools & Service Desk Escalation: Serve as Tier 3 escalation support for engineering applications, toolchains, build environments, license managers (FlexLM), and core network/directory services (DNS, DHCP, LDAP, Kerberos, NTP).
• High Availability & Disaster Recovery: Design robust backup and recovery workflows, test system failover procedures, monitor system health/telemetry (Prometheus, Grafana, Zabbix), and resolve complex performance bottlenecks.

Basic Qualifications (Required Skills & Experience)

• Education: Bachelor's degree in Computer Science, Information Technology, Cybersecurity, or equivalent combination of education, technical training, and experience.
• Experience: Minimum of 8-12 years of total IT infrastructure experience, with at least 6+ years focused on enterprise Linux systems administration.
• Distribution Mastery: Deep, hands-on administration of Oracle Linux (UEK), Red Hat Enterprise Linux (RHEL), and Ubuntu Server/Desktop.
• Fleet Management: Proven experience managing Linux endpoints at scale using Canonical Landscape, Red Hat Satellite, or Foreman.
• Authentication & MFA: Demonstrated experience implementing Linux desktop and SSH Multi-Factor Authentication (YubiKey, PKI/Smartcard, Duo, or Okta PAM integration).
• Compliance & Hardening: Direct experience hardening Linux environments to NIST SP 800-171, CMMC Level 2, or DISA STIG requirements.
• Automation: Strong proficiency in Ansible and scripting with Bash or Python.
• Virtualization & Storage: Solid experience with VMware vSphere/ESXi and enterprise storage management (LVM, NFS, iSCSI, SAN).
• Security Clearance / Export Control: Must be a U.S. Person (U.S. Citizen or Lawful Permanent Resident) due to compliance with ITAR/EAR regulations; ability to obtain and maintain a DoD Security Clearance if required.

• Active industry certifications: RHCE / RHCA, LPIC-3, CompTIA Security+, or CISSP.
• Experience with containerization and orchestration platforms (Docker, Podman, Kubernetes).
• Hands-on experience integrating Linux infrastructure with Oracle Cloud Infrastructure (OCI), AWS GovCloud, or Azure Government.
• Familiarity with Linux kernel tuning, custom repository mirroring, and local software distribution pipelines.
• Exceptional analytical and troubleshooting skills under time-critical operational conditions.
• Strong written and verbal communication skills; ability to document standard operating procedures (SOPs) and compliance artifacts clearly.
• High ownership mindset with a focus on cross-functional collaboration across Infrastructure, Security, and Engineering teams.
