The "Automation & Low-Latency" Premium
If you only know how to manually configure VLANs and basic OSPF via the command line, your salary will cap out around £65,000. To push past £110,000, you must achieve one of two things: obtain a CCIE certification and master Network Automation (DevNet), or transition into Low-Latency Financial Networks. If you can use Python to automate complex network deployments or shave milliseconds off trading routes, you transition from a manual operator to an elite Network Architect.
