Job for a mathematician?

Hello!

My name is Agnieszka and I'm planning on moving to the UK in the nearest future. I would like to ask about the job opportunities for Mathematicians and if there is a chance of securing a position from Poland?

I have savings that I hope would allow me to survive for approximately 3 months in London.

I have a Masters in Mathematics from Jagiellonian University in Poland (one semester student exchange in the UK), since February I have been working for Capgemini as a Finance & Accounting Process Analyst. I would prefer to find a position that has actually more to do with Mathemtical Modelling or Data Analysis, but of course at the beginning anything would do for me.

Thank you for any advice!
