Scientific Programmer and Developer

I am a theoretical Physicist (PhD, semiconductor research) and software developer. I have broad experience in scientific programming, web and application development with Python and the usual front-end stuff, and I've worked a lot with data storage and processing. At the moment I work for a large German car maker in the R&D department, but I'd like to do something more meaningful. My ideal job combines math/natural sciences and professional software development, with enough flexibility to spend time with my family.
