Well I only work on new stuff/deployments for data centers. Once it's deployed it goes to ops for support. I don't know if you have a lot of experience in large networks but there is a lot of break/fix work with failing hardware components and physical issues ..but that's not the side of the house you want to be in because operational stuff like NOCs are always high turnover fast-paced jobs where everything is your fault. If you're going to work networking you gotta transition to the "money-making" side of the house for better quality of life. Right now the "sexy" stuff is devops/automation and that's where a lot of gripe comes from with the old school CLI guys because they don't want to learn anything new.

Job before this was at a university with a small team of infrastructure engineers and you would think their job was to stifle progress. Their whole team and millions of dollars in expensive networking equipment could get replaced by a private cell tower.

Cyber security field is a bit different, companies know now they have to spend money on it now so the faucet is open. Most of the real preventative methods for security happen at the network. Security guys that are paid deep into six figures know networking, Linux, programming and other things.

Being an SME and earning the big bucks, in my opinion, is about knowing quite a bit about many things
