* Support production/live environments and participate in handling critical and high-priority incidents when required.
* Document incidents, root causes, corrective actions, configurations, and technical procedures.
* Maintain accurate ticket and task information, including priority, status, troubleshooting steps, actions taken, and final resolution.
* Use the company’s ticketing and project management systems on a daily basis to manage support tickets, tasks, and project activities.
* Communicate professionally with customers and internal teams and follow incidents through to full resolution.
* Contribute to the internal Knowledge Base by documenting recurring issues and proven resolutions.
Technical Requirements

* Ability to install and configure SSL certificates on application servers.
* Solid understanding of networking fundamentals, including:
* TCP/IP
* VPN
* Firewalls
* Ports and connectivity

* Proven experience supporting production/live environments, not only development or testing environments.
