Experience:
3–5+ years Employment: Full-time Join ReBrand Gurus ReBrand Gurus is a boutique creative technology agency working with businesses across website development, mobile applications, digital marketing, SEO and other digital solutions. We manage multiple client websites and digital platforms, and we are looking for an experienced Senior Server & Infrastructure Security Administrator to take ownership of our hosting environments, server infrastructure, website security, and technical troubleshooting.

About the Role
We are looking for a technically strong professional who can keep our web infrastructure secure, stable, monitored, and recoverable. This is not a regular WordPress developer or basic Server Administrator role. We need someone who understands server-level security, can investigate complex technical problems, and knows how to protect multiple websites from vulnerabilities, malware, server failures, and unauthorized access. The ideal candidate will take responsibility for identifying potential risks, preventing avoidable downtime, investigating security incidents, and restoring services safely when unexpected problems occur. Your primary responsibility will be to protect ReBrand Gurus' web infrastructure and ensure that our websites remain secure, stable, and recoverable.

Key Responsibilities
1. Linux Server and Hosting Management
• Manage and maintain Linux servers, VPS environments, and website hosting platforms such as Hostinger, hPanel, cPanel, and similar services.
• Monitor server health, CPU/RAM usage, disk space, uptime, resource consumption, and website performance.
• Investigate and resolve server-level problems affecting one or multiple websites.
• Manage PHP versions, MySQL/MariaDB databases, cron jobs, file permissions, and server configurations.
• Work confidently with SSH and the Linux command line for server administration and troubleshooting.
• Perform routine server maintenance, software updates, security patches, and configuration reviews.
• Handle website migrations, hosting migrations, and server configuration changes safely.
• Identify infrastructure weaknesses and recommend improvements to server stability and security. 2. Website and WordPress Administration
• Manage and troubleshoot multiple WordPress websites hosted across different environments.
• Diagnose plugin, theme, PHP, database, and compatibility issues.
• Resolve website downtime, HTTP 500/502/503 errors, database connection failures, and other server-related website problems.
• Perform WordPress core, plugin, and theme updates safely.
• Troubleshoot WooCommerce websites and related technical issues.
• Maintain staging and production environments.
• Investigate website performance issues and implement appropriate solutions.
• Work with developers to resolve application-level problems when required. 3. Server Security and Malware PreventionThis is one of the most important responsibilities of the role.

• Identify possible entry points and determine how a security compromise occurred.
• Investigate compromised administrator accounts, vulnerable plugins, outdated software, and insecure server configurations.

• Check related websites and accounts when a shared server or hosting setting may have been compromised.
• Verify that security incidents have been properly resolved and monitor for signs of reinfection.
• Maintain practical security procedures to reduce the risk of future incidents. Important: Removing infected files alone is not sufficient to resolve every malware incident. The candidate must understand how to investigate the original entry point, identify possible backdoors, assess the wider hosting environment, and prevent the same vulnerability from being exploited again. 4. Backup and Disaster Recovery
• Configure and maintain automated website, database, and server backups.
• Maintain appropriate backup retention and access controls.
• Ensure backups are stored securely and independently of the primary environment wherever practical.

• Troubleshoot A records, CNAME, MX, and TXT records.
• Configure and troubleshoot SPF, DKIM, and DMARC records.

• Configure alerts for downtime, unusual resource consumption, suspicious activity, and backup failures.




• Identify potential issues before they develop into major disruptions.
• Conduct routine reviews of server configurations, access permissions, software updates, and security settings.
• Maintain documentation of servers, hosting accounts, websites, domains, and technical configurations.

• Can independently investigate and resolve infrastructure-related problems.
• Understands how server-level vulnerabilities can affect multiple websites.
• Takes ownership of technical issues from investigation to resolution.
• Follows a systematic troubleshooting process instead of making random changes.
• Prioritizes preventive maintenance and long-term solutions.

What Success Looks Like The successful candidate will become the technical guardian of ReBrand Gurus' web infrastructure.

You will also be responsible for strengthening our infrastructure, identifying risks before they cause disruption, maintaining reliable recovery options, and reducing the likelihood and impact of future security incidents. Our expectation is not simply to fix problems when they occur, but to build and maintain an infrastructure that is secure, resilient, and prepared for unexpected failures.
