Swastika,I guess you should direct this question to a forum more focused in your domain. As per your experience and domain knowledge most engineering companies would value your experience. As per your aspirations "[i]Am more interested for job responibility like modeling and simulation, system identification, control logic design, (preferably in aerospace domain.)[/i] " surely your employer may not be a management consulting firm if you want to progress into engineering however PA Consulting may be an option among MC firms.You may look for companies in the likes of Altran, BAE systems, Bombardier, Eaton, GE aviation, Honeywell, QinetiQ,Thales, UTC Aerospace (merged with Goodrich Corporation), Ultra electronics to name a few and to consider depending on you location.Good luck
