I would say EE or CS are safe bets. Most technologies these days are using electrical knowledge in one way or another. I studied MechE and wish, to some extend, that I studied EE or CS. It really is the future of tech. However, it is still very possible to get an SE job with other engineering degrees (like me). If you’re still interested, https://moderntechsales.com is exclusively for Sales Engineers.
