Looking for a new job and advices

Hi everyone. I’m looking for a new career. After some years as Math teacher and after more than a year on CG I want to change my job and I can’t be specific about what it should be. So I ask all of you about it, in order to help me.
Here is some info:
I love Math
I love writting algorithm to solve problem
The only language I know is python (and I’m not sure I want to learn a new one)
I want at least 30K€/year

At the beginning, I was looking for data analyst or data scientist. But not sure now.

Thanks for your help and advices.
