let this be clear and give you some hope that, there are good embedded MNC's tie up in egypt who work on embedded systems....
they are also in need of embedded engineers who can contribute single hand (of course in a team)....
I would say most of the work done on embedded side involves work on LINUX platform, so you being from any discipline of engineering need a good knowledge on RTO's....
there is also huge requirement in 32bit processors and if possible good knowledge on android... if not 32bit indepth knowledge is required because its hard to find people in those region and outsourcing is difficult...
i suggest you to learn 32 bit controller with extensive C programming skills and learn RTOS basics concepts in deep...
probably MICRIUM OS would be very helpful for you......
