Careers in London + NYC

I am interested in a career in finance that would allow me to work in both London or Europe and NYC. I have worked at a large BB bank for the past 2 years in nyc in a client-facing FO role in S&T. I am looking to make the move to the buy-side and work in IR or BD / Corp Dev. Additionally, I am interested in a role that would allow me to work in both nyc + london. I know this is very niche, however, I am interested to hear thoughts on any type of finance role that would allow me to accomplish this goal.
