  • Operational Support and Troubleshooting:
    • Serve as an escalation point for both the Operations Center and other Unix team members.
    • Triage and resolve infrastructure issues, providing root cause analysis.
    • Work closely with application, storage, and network teams to resolve cross-domain service issues.
    • Work with the Backup team to ensure consistent backups of all Linux servers.

    • Implement and maintain system security in accordance with federal standards (NIST, FISMA, and DISA STIGs).
    • Manage user access and system entitlements, including SSSD/LDAP/Active Directory integration.
    • Troubleshoot and resolve SELinux problems.
    • Participate in security audits and provide remediation for findings.
    • Participate in an on-call rotation for 24/7/365 operational support.
Requirements
  • Must be a U.S. Citizen.
  • Must be able to pass a background investigation to obtain and maintain a Public Trust security clearance.

  • Strong experience in Linux performance tuning, kernel parameter analysis (sysctl), and troubleshooting with tools like vmstat, iostat, sar, and perf.
  • Expert-level scripting with Bash and strong proficiency with Ansible for configuration management and automation.
  • In-depth knowledge of Linux storage (LVM, XFS, NFS, CLVM) and networking (TCP/IP, DNS, bonding).
  • Expertise across RHEL 7, 8, and 9 environments.
Preferred Qualifications
