Not just that you can do it but I will moreover encourage you to go for higher degree. A work experience of 4 years will be helpful in getting and admit to a good University and also in post-MS job hunt. You can try good SOP, GRE and Recommendation letters you can score a good University. You can pursue MS in mechanical engineering in in one of the top IIT or other institutes for you can pursue MS abroad. Thank you. Good luck .
