What does a network engineer do?

I do work from home daily. I remotely log into my corporate vpn, and from there can access our tools network and bastion hosts that then allow me to access our clients network devices.

90% of my work is project based, as in the client companies decide they desire to do thing x - and then I design and implement, then handover to operations. Once the handover is done I generally do not reengage the devices unless another project comes along involving it.

Typical projects, vpn connections, circuit/hardware upgrades, end of service life projects, wireless deployment, authentication and ISE, site redesigns, site shutdowns and moves, new floors in existing buildings, divestments and acquisitions where you integrate two companies together or segregate them. 75% is bread and butter IOS layer2 and layer3 switching and routing.

I spend a lot of time reading email, sitting on conference calls, thinking of ways things can fail, and what would happen if thing x failed and no one noticed and later thing y failed for a completely different reaspon - what would happen and how would you prevent it. Or thinking, knowing everything I know about this design, if I had an ax and 60 seconds - how much damage could I really do.. and then preventing that ability in architecture design, doing marathon change implementations, and updating visio drawings. I frequently write perl scripts to automate tasks, but I never share those - they are for my use only. I do a lot of those in my underwear.

I never ever speak with end users.
