There are many engineering majors who work in Tech in IBs.
If you want it, shoot for it.

Starting salaries for fresh graduates aren't too shabby.
Obviously it varies according to which IB you join but the spectrum lies between 40+ and 70+.
What doesn't vary across IBs is the hours that you'd have to put in.
The push for delivery of technological solutions to support business and regulatory requirements is tremendous. Teams are global and you'd be expected to work during London and North American business hours.


Work hard and smart, and you'd progress to the next level in 2 years or so.
From then on, working hard and smart becomes a fundamental and you get no cookie points for that. It'll take another set of skills to climb further; you'd discover the nuances when you get there.

Good luck!
