Need advice on working for Credit Karma- halal or not?

I wanted to know if working at Credit Karma company as a sofware engineer helping them expand to UK and Canada is halal atleast temporarily or not. I am a single female staying in Spain and have issues finding a halal marriage, there are only haram relationships possible here, so after trying for years, i thought to move to the UK where i could get more muslims and a better muslim environment.

I have gotten a job offer from Credit Karma company which helps people read and manage their credit score, identity theft, but they also recommend insurances, loans, credit cards whether with 0% interest or with actual interest and earn with people paying for their services or by commission when people buy these credit cards and loans. The Credit Karma segment offers consumers with a personal finance platform that provides personalized recommendations of home, auto, and personal loans, as well as credit cards and insurance products. It sells products and services through various sales and distribution channels, including multi-channel shop-and-buy experiences, websites and call centers, mobile application stores, and retail and other channels. A good credit score comes handy so many seemingly unrelated places. For example, buying a house, a car, rent an apartment, or get a job.

I can accept the offer and work for them temporarily until i find another job. I want to understand if the income is haram from day 1 or not. Or i can take it to open doors to so many other UK jobs which require me to be there already to consider me.

Please let me know.
Thanks!
