May be after 2019 elections. Till then you must update your skills. You will be able to get into defense department in a suitable post. Or anything to do with the significations of Mars which you can read from my blog or from internet.
I suggest you continue doing job till 2020 then after 2020 you can start your own business as that period will be favorable.Currently you are running Ketu antar dasha which shows travel related to your career.There will be ups and downs during this period which will be running till Nov 2018.I advise you perform remedies for Ketu.
