You should be laser focused om what this person needs to do for you not what shape they might come in or where to find them. For example, you may say "we need someone to do everything tech" which I would frame as laser focused on a generalist and then write down the attributes of someone that would fit that and start sharing it.
We used angel list jobs at the time and I posted here on the monthly "who's hiring" thread.
It is going to take a lot of time to interview. Be prepared to spend money on a recruiter ($30k and up per hire) or 50% of your week (or more) talking to folks.
As you grow your team follow the "hire when it hurts" advice and make sure you know what you are bringing another body in for because it is gonna add to communication overhead. I also recommend explaining to your team why you are hiring and what you need as you grow and dont just show up with surprise hires.
Once you get your posting out there you will get good candidates.
If you are ready to pay for great talent then I can also recommend reaching out to Recurse Center for candidates. https://recurse.com
