Field
Support & Operations
Keep people working and live systems healthy — the real front door to IT.
This is where most IT careers actually begin, and it is badly undersold. A year on a service desk or a NOC floor teaches you how systems fail, how organisations behave under pressure, and which part of the stack you find yourself reaching for. Almost every senior engineer in the other six domains started here.
