What's the equivalent of a financial clerk in finland? I'm trying to change careers

Hello all I've been a nurse in finland for 6 years now and it sucks. I still don't have a permanent work place although I'm never unemployed for longer than a week the work is hard, the salary is low and I can't get a permanent work place anywhere that I've liked working.

So I want to be a financial clerk but idk what that's called in finnish or if that specific job is exactly the same or what degree is needed? Can anyone help me please? My finnish is really good so that's not a problem 👌
