Must I leave the Quran memorization center, which I need to improve my recitation (tajwid) and consolidate my memorization, for the sake of a job that helps me pay for university expenses, knowing that not taking the job might prevent me from entering university?

Firstly, it is better to combine memorizing the Qur'an and Tajweed with work and university studies, provided that the work and studies adhere to Islamic law. If it is possible to combine them, then obeying both is better. However, if combining them is difficult, then you are not obligated to obey your parents regarding work or university, and this is not considered disobedience. So, prioritize whichever is more beneficial for you.
