I’ve had luck finding early-stage startups through a mix of places:

HN “Who’s Hiring” threads (great for early opportunities straight from founders).

AngelList / Wellfound for more structured job boards.

Direct outreach - if you see a product you like, email the founder. Early teams usually respond well to proactive people.

It’s less about waiting for a job post and more about finding projects you’re excited about and reaching out early.
