How to get started in quant trading?

I am in my mid-20s. and have worked at late stage SF tech companies as a SWE and Data Scientist for the last 5 years. I am fairly skilled at WebDev, Algorithm Design, and Machine Learning (College level, not research).

I have always been fascinated by quick feedback loops and dynamism of financial markets and exploring a career there and have consumed a lot of literature on fundamental investing.

How do I go from here to a job as a quant trader in terms of acquiring relevant skills, lining interviews and landing a job? Any help would be great!
