Infrastructure Engineer (3rd Line)

This is the senior escalation point on our service desk and the engineering muscle behind our project work. One day you're getting to the bottom of a problem two other engineers couldn't crack, the next you're designing and delivering a migration, a network refresh or an Azure environment for a client who'll know you by name. We're vendor-independent, so you won't be boxed into one stack. Microsoft 365 and Azure sit alongside FortiGate, UniFi, VMware, Linux and whatever else the right answer happens to be. If you like variety and being trusted to make the call, this is that job. Responsibilities: Act as the final technical escalation for the service desk, owning complex incidents through to root cause; Design, implement and document infrastructure projects: migrations, networks, virtualisation, cloud; Administer and improve client environments across Microsoft 365, Azure, Windows Server and networking; Mentor 1st and 2nd line engineers and raise the technical bar across the team; Take part in the on-call rota supporting our 24×7 clients
