I used to work for Misys until recently. They are doing some development on their Summit application
http://www.misys.com/products/summit-ft.aspx in the far East as well. You could try to look 'em up, although if the work conditions are similar to what the offer in Romania, you're probably better of in a different company.
Also, you should note that the entire backend of the application (which runs on a complex distributed server architecture) is written in C, which they tried really hard to upgrade to C++, and it ended up being a big maintenance from hell nightmare. Also, they decided to make a "fancy" C# frontend desktop application for that backend, which is full of bugs. As a side note, don't expect much documentation about the code structure and internal logic, just many 6000+ line functions of C code
;)
