Position Overview

The IT Infrastructure & Support Administrator is responsible for the health, performance, and security of Gemma's network, hardware systems, and software applications.

Infrastructure & Network Administration

• Install, configure, and maintain servers (Windows and/or Linux), storage, and virtualization; manage capacity and performance.
• Implement and maintain network and endpoint security — firewalls, antivirus/endpoint protection, patching, and access controls.
• Design and maintain backup and recovery for servers and critical data; participate in disaster-recovery planning and testing.
• Manage user accounts, permissions, and directory services (e.g., Active Directory), including onboarding and offboarding.
• Monitor infrastructure proactively and respond to alerts to minimize downtime for critical systems.

End-User Technical Support

• Provide responsive technical support to on-site and remote employees — hardware, software, network connectivity, email, and business applications.
• Log, manage, and resolve support tickets through to closure; escalate complex issues appropriately.
• Set up and configure end-user devices — PCs, laptops, printers, peripherals, and mobile devices.
• Administer and support common business and collaboration tools (e.g., Microsoft 365 and email).
• Maintain documentation, knowledge-base articles, and IT asset and inventory records.
