Unfortunately, its still a male dominated society with respect to traditional skills like engineering, however, bazzmaro is right to suggest trying european companies who are more inclined to hire someone based on their skills and experience. Things you will have to accept, though, are; firstly, your wife may have to be comparably more qualified and/or experienced than her male counteparts, and, secondly, she would most probably be remunerated less than them too.
However, there are exceptions in all situations and you should apply and see.
