How to get a job in startup?

I am a data engineer with 2 years experience in python, SQL, AWS, spark stack. I am looking for a switch and my priority is to get into startup as I get to learn a lot, atleast that's what I believe. I am not sure though how to get there. I am applying on naukri and LinkedIn, and I am unable to find startups to apply to. I can only see midsize businesses or big corporations. I don't know anyone who works for a startup, and don't know how to network with those folks specifically. It will be great if you people can provide guidance for networking and searching job in startup
