From the field
The same lessons come up again and again from people actually doing the job:
People think it's just fixing phone signal. It's far bigger — designing network architecture, optimising performance across thousands of sites, troubleshooting complex faults, and rolling out 5G. When millions of people depend on the network you run, the engineering is serious.

The 5G rollout created huge demand. Networks are getting more complex and more essential, and there aren't enough people with the skills. That makes it well-paid and future-proof — connectivity isn't going anywhere, and someone has to build and run it.

It's deeply technical and the on-call can be demanding — when a network goes down, people notice immediately and you have to fix it fast. But the career is strong: from engineer to specialist to network architect, designing the infrastructure that keeps a whole country connected.
