Working at a ritzy quant firm shouldn’t impact your competitiveness for PhD programs too much (could even improve it), and if you’re getting $1M+ / 5y E2G-worthy offers halfway through ugrad (and have already published!), you’ll probably still be able to get comparable offers if you decide to e.g. master out. So in that regard, it probably doesn’t matter too much which path you take, since neither preclude reinvention.
If it were me, I’d take the bird in hand and work in the quant role… but if I felt myself able to make more meaningful “direct” contributions, focus on not just E2G’ing but also achieving financial independence as soon as possible. PhD program stipends are quite a bit lower than industry pay (at my current school, CS students only make around ~$45k / y), so being able to supplement that income with proceeds from investments would free you from monetary concerns and let you focus your attentions on more valuable pursuits (e.g. you wouldn’t have to waste time on unpleasant trivialities, like household chores, if you could instead hire a regular cleaning service + meal delivery. Hell, spend another year or two at the firm and get yourself a part-time personal assistant for the duration of the grad program to manage your emails for you haha). Focus on solving those claims on your time that can be most cheaply solved first, to give yourself greater opportunities to direct more valuable hours down the line.
