About the role

Trust Systems is actively seeking a 3rd Line (Infrastructure/Server/Desktop) Support Engineer to join our team based at a customer site in Corsham, Wiltshire.

Project-Based Installation and Deployment: 
Collaborate on-site for project-based installations and deployments, contributing to the seamless integration of new equipment and systems into our infrastructure. 

Configuration and Management of Server Environments: 
– Configure, manage, and maintain diverse server environments, encompassing Windows Server 2019 and above, as well as Linux-based operating systems. Ensure these environments are optimized for performance and security. 

– Excel in configuring, managing, and maintaining virtual environments, predominantly leveraging VMWare technologies (on-premises or via vCloud instances). Additionally, manage Nutanix instances to ensure seamless virtualization operations. 

Planned Preventative Maintenance (PPM): 
Conduct Planned Preventative Maintenance activities, including comprehensive System Health Checks and Physical Inspections, ensuring the ongoing health and resilience of our infrastructure.
