[Hiring] Linux Systems Administrator @World Business Lenders, LLC

Role Description

We are seeking a Linux System Administrator who will be responsible for installing, configuring, securing, and maintaining the organization's Linux-based servers and associated infrastructure within an Azure Cloud environment. This position ensures that critical systems remain reliable, efficient, and recoverable, allowing business applications and services to operate seamlessly and securely.

Key Responsibilities:

• System Installation, Configuration & Maintenance:
  • Install, configure, and maintain Linux servers (physical and virtual) in production, test, and development environments.
  • Apply OS patches, kernel updates, and software upgrades in a controlled, documented manner.
  • Configure and manage key system services (e.g., SSH, web, database, cron, logging) according to standards and application requirements.
  • Maintain accurate system documentation, including build sheets, runbooks, and configuration records.
• Availability, Performance & Monitoring:
  • Monitor system health, capacity, and performance using standard tools and dashboards; proactively address emerging issues.
  • Troubleshoot and resolve OS-level, hardware, and basic network issues impacting Linux servers.
  • Implement and maintain backup and recovery procedures; regularly test restores for critical systems and data.
• Security & Compliance:
  • Harden Linux systems by configuring firewalls, access controls, logging, and OS security settings aligned with company policies.
  • Manage user and group accounts, permissions, and sudo access to enforce least-privilege principles.
  • Apply security patches promptly, monitor logs for suspicious activity, and support incident investigation as needed.
• Automation, Scripting & Standards:
  • Develop and maintain shell scripts or simple automation to streamline routine administration tasks (e.g., deployments, checks, housekeeping).
  • Contribute to standard operating procedures and configuration baselines for Linux systems.
  • Support use of configuration management or orchestration tools where in place (e.g., Ansible, similar).

Qualifications

• A Bachelor’s degree in Computer Science, Information Systems, or a related field is preferred — but we also highly value equivalent hands-on experience!

Requirements

• 3 to 5 years of hands-on experience administering Linux servers in a production environment (e.g., RHEL, CentOS, Rocky, Ubuntu).
• Strong knowledge of Linux command line, system services, filesystems, and package management.
• Experience with system monitoring tools and log analysis for troubleshooting performance and availability issues.
• Solid understanding of TCP/IP networking fundamentals as they relate to Linux servers (DNS, routing basics, firewalls).
• Demonstrated experience with user and permission management, SSH, sudo, and basic security hardening.
• Scripting proficiency in Bash; exposure to another scripting language (e.g., Python) is a plus.

Benefits

• USD Base Salary.
• Enjoy Paid Time Off (PTO) after just 6 months of service.
• Full-time opportunity.
• Enjoy the freedom of a completely remote work environment!
