Your Rah is excellent from placement point (6th house) and has decent combinations for career. MErcury is bad for career as it has 6,12 in nakshatra and sublord that shows meagre growth/survival.
Ketu antradasha starts from 23/10/2017 and will be better than Mercury as Ketu has 2,7,10,11 in nakshatra and planet. But as Ketu is placed in 12th house in natal, it may incline you towards spirituality.
From October end, as Saturn moves to 3rd house in transit + Jupiter transits your lagna and Rahu moves to 10th house you can expect stability + peace.
You will get a great jump in life in Rah-Sun 11/11/2021 to 5/10/2022 as Sun is 11th lord and has excellent combinations for career.
Chanting Om Bhraam Bhreem Bhraum Sah Rahave Namah 24000 times in 21 days will help.
