If I google management recruiter and my city, I get a lot of them, including one that says “executive and IT”.

But the ones I personally used I found one through my brother and one through a lover so maybe just ask people you know IRL too. People who have jobs like the one you want, preferably.

I think we got our IT staff and management by posting jobs on external boards, Teamwork Online mostly. Some from recruiters though, that’s how they got me. Both my good jobs were temp that turned into permanent positions.
