The ideal candidate will be responsible for maintaining and troubleshooting the RHEL environments that host many of the applications used to collect, analyze and disseminate official Census data.

In addition, you will proactively identify opportunities to improve operations, form a plan and implement it.
Salary range for this position is up to $130,000 depending on qualifications, including relevant certifications, education, years of experience, and demonstrated experience supporting Federal Government programs within the field.

    • Perform kernel-level tuning (sysctl), I/O optimization, and network performance analysis.
    • Troubleshoot and resolve complex performance bottlenecks related to CPU, memory, storage, and networking.
  • 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.
  • Security and Compliance:
    • 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.
  • Bachelor's degree in Computer Science, Information Technology, or a related field (or 7+ additional years of equivalent experience).
  • 10+ years of dedicated experience as a Linux/RHEL Engineer or Administrator.
  • 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
  • Active Public Trust clearance. 
  • Red Hat Certified Engineer (RHCE) or Red Hat Certified Architect (RHCA).
  • CKA or CKAD
