Is it time to quit my startup SDE role?

Been working with a pre series A level startup for about 3 years being my first job. Paid about 20-25lpa for a full stack role. Engineering + product team is still single digit strength as we are not pureplay tech company. Had a great learning because of a good manager and 0-1 kind of work we did but I am starting to feel stagnated because of following reasons 1. We don't have anything like SDE1, 2 etc because there are very few devs. 1 manager and everyone else is an SDE. The company doesn't intend to hire more for at least an year.. so i won't see any title level promotion or any role that feels senior despite being around for a while 2. Salary. Want to know if I am behind the standard pay because i belong to tier 1.5ish college. Big tech seems to pay more for 3yrs workex as usually people become sde2 by then
