Question about transitioning from banking to a more heavy algorithm related job

Hello,

I am currently a sophomore at UMich Ross studying Computer Science with a heavy emphasis on algorithm design and analysis. I posted 3 months ago about whether I should take the NWM Financial Advisory Internship and I am glad you guys told me to get the fuck out. Digressing from that, I have some quick questions that I would appreciate an answer to.

Currently I have signed offer letters for two internships, one for Software Engineering at Amazon and a PE analyst one at a (decent?) company. I am 95 percent sure that I want to pursue banking because I hate software engineering with a passion. If I am to do my best in IB recruiting, will taking the PE role really be that more beneficial, because if it will not be, I would rather take Amazon for this summer($61/hr vs $45).

Onto my next question, I have a relatively high level understanding of financial algorithm design, I have conducted some research and this is the topic that really fascinates me. After doing some years as an analyst, does anyone have some experience with transitioning to a more research heavy part of the bank (still want money of course) or does it help with recruiting QR? While I do think that I would be an excellent fit as an analyst and my pitch-deck making skills are quite strong, I truly excel as a mathematician and that's where I would be of most use. I appreciate any advice!
