My number one book recommendation on the topic is "Managing Humans" by Michael Lopp (Rands in Repose). If you want to get some of the content for free [and see if the author's style works for you], check out the blog first perhaps: https://randsinrepose.com/archives/category/management/
In terms of advice, don't overlook or look down on yourself in regards to just mentoring this one guy. It's a perfect starting point and maybe check in with the founder or your direct boss to express that you'd like to progressively get more involved here.
My (and many people's) first leadership role was a team of two, which I later grew to a third dev and we shipped an entire Playstation game after I made and overcame many mistakes as a team lead. I'm glad to have had the chance to make those mistakes in a small team; the same mistakes on a team of eight may have been impossible to recover from as my first experience.
In that type of a role, you are still hands-on coding 70+% of the time, which in many ways, I found to be an incredibly enjoyable mix, and gives you a taste of leadership to help you decide whether you want more or that or not. I enjoyed that journey and, when it comes time to retire, I'm somewhat likely to take that level of 3/4-IC and 1/4-team lead role again.
