There are some startups I work with that are still hiring in-person only. And conversely, I've spoken with a number of candidates who are (not surprisingly) sick of remote work -- and open to relocating. That market still exists, and we'll see how it plays out in the next couple of years.

At workatastartup.com, you can filter by "Not remote" jobs, but it's probably not as intuitive as it could be. We need to revamp some of our search filters accordingly. But until we have it, feel free to email me (ryan AT ycombinator DOT com) and I'll do what I can to help you find ones that might be a good fit.
