Software Engineer + SDM Marriage?

I am a software engineer and my parents received a call from a girls family. Both our native places are the same. We have grown up with same set of values. Everything looks damn perfect except for 1 thing. She is a SDM in same state. This is a good point for me as it shows her hardworking nature by cracking a tough exams. Even I am looking for someone who has been really hard working at some point in there life. But thus public sector job has its cons as well, which is transfers and postings to different places within same state. We are now talking since past week. She says she will try getting her transfer done to my place after marriage and that it is possible as well. She gives me example of her colleagues where private and public sector combination worked out. I also feel convinced many times but some days I feel like I will be restricting my job opportunities in other places. My place of work gets automatically constraint to my current one. Although it is closer to my hometown and eventually I plan to settle there. But always in my life I have kept my options open for place and company I work at. Being an SDM has its attraction I agree but it is this aspects which is playing a negative role for me. In my family everyone is a private sector employee and those who were in public sector have shifted to private as well. For her everyone in her family is government job holder. Please suggest what should I do as our parents would need some answer from me. She will have same setup with any other person so she doesn't have much to ask me, it is me who asks about our future setup is going to workout.
