Excellent background, especially the HPC and cloud experience. It's all about scale and performance. I would start with http://www.wilmott.com/jobsboard/ I'm not sure I have any good suggestions based on your location, other than to look at Frankfurt. Lots of financial business in that general area.
When you get there, paddle upstream and cross the border. Go past the first town (it smells like chocolate). Keep right and come to a lake. Walk down the street to the railroad station. read signs along the street. Do not conduct interviews on the lower floors. Have tea while inside and hope to get asked to go for coffee (they will say "like in Chacago"). Drink it black.
Thanks Vikana, that is a useful information! I will give a try. I am a "perverted one" . I like to play with regression models and with high performance computing use cases. I work with use cases coming from nuclear physics, smart grid and telco. If you are curious you can find a link to my homepage in the description of my profile. Shop around and if you see something that you like let me know.
