• Maintain and optimize the virtualization layer for stability and performance.
• Handle provisioning, templating, backups, and automated deployment of macOS VMs.

Required Qualifications

• Proven experience with VMware ESXi and virtual machine lifecycle management.
• Hands-on knowledge of macOS system administration, including Terminal, launch agents, and system daemons.
• Familiarity with Intel-based server platforms (e.g., Xeon Gold/Platinum) and enterprise server hardware.
• Experience providing remote console access (HTML5 consoles, VNC, or custom portals).
• Solid troubleshooting skills for both infrastructure and macOS-related issues.
• Strong English communication skills (written and verbal).

Preferred Skills

• Knowledge of macOS automation (Bash, Zsh, AppleScript, configuration profiles).
• Familiarity with Xcode build environments and mobile development workflows.
• Experience working with customer-facing hosting platforms or remote desktop environments.
• Exposure to storage systems (NAS/SAN) and backup tools for virtual machines.
• Understanding of Apple licensing terms and how to maintain compliant macOS deployments.

What We Offer

• A rare opportunity to work on innovative macOS hosting services in a non-traditional environment.
