• Collaborate with cross-functional teams including network, database, and application teams
• Communicate system changes, downtime, and impacts to stakeholders and end users
• Ensure backup and disaster recovery solutions are properly implemented and tested
• Conduct post-migration audits and identify opportunities for system optimization

 

Required Qualifications:

• Minimum 8 years of experience in system administration with both Windows Server and Red Hat Enterprise Linux
• Strong experience upgrading and migrating legacy systems to modern platforms
• Hands-on experience with Windows Server (2008–2022) and RHEL (5–9)
• Proficiency in scripting and automation using Bash, PowerShell, and/or Ansible
• Experience with configuration management tools and system automation

• Experience working in large-scale enterprise or government environments
• Knowledge of backup and disaster recovery solutions
