How does one transition to this? Is there "we don't hire Americans" / "we don't hire over 35" in this area?
Transition to CCIE plan
Buy books, study, practice on home lab - repeat for each level of certification. Most can complete the full path in less than 4 years of after work hours study. Some can do it in two.
Certifications in order:
Comptia Network+
Cisco CCNA Routing and Switching
Cisco CCDA
Cisco CCNA Security
Comptia Security+
Cisco CCNP Routing and Switching
Cisco CCNP Security
LOTS OF study and lab time
Cisco CCIE written
Cisco CCIE Lab
Process took me 2 years and passed the lab on the 3rd attempt (typical). Got mine back in 1996
“How does one transition to this? “
First, don’t listen to the CS professor.
Second, start the Cisco curriculum of self study.

Expect to put more time and effort into a CCIE cert than you would into a BSEE. And far less money.
Just an entry level CCNA cert gets you employed at $30/hr +.
And never, ever think it’s going to be easy.
