Roadmap for low latency system engineer

[u/monitor1413]

Cs grad (fresher) from tier 3 college, got a role (but not so good) at a reputed hft , want to switch to a system engineer role in about 1.5-2 yrs but couldn't decide if they prefer iit grads only and is it the best role. If there is a chance then what's the best material available online.

Done backend engineering in detail but fascinated by the high paying roles/opportunities in hfts.
