So I like this guy at my job

So I like this guy at my job and I want some to know some ways how I can shoot my shot and let him know that I’m interested too. I’m 22 and never really had a real bf (more like flirtations that turned into nothing or friends) because I’m picky and get turned off easily. We’ve been working closely together for maybe a month now and He has done things to definitely tell me he’s interested within the last week or 2 but I’m wondering how I can tell him I’m interested too without being way too forward. We have good chat and jokes and he basically ticks all my boxes and I don’t want to fumble this. And I don’t really care about him being a co-worker since we’re only at the office maybe 2 hours a day which isn’t a big enough deal to not try to talk to him.
