Which aircraft do you have an opportunity to upgrade on?
There is definitely an active upgrade program at Qatar Airways, and depending on fleet probably about 4-6 years wait at present.......there are a lot of hoops to jump through and failure is always a possibility
If you are able to upgrade at present company on Boeing / Airbus you will soon have many options to join as Captain in various airlines
There are many other factors such as whether you prefer long haul, on a wide body vs narrow body etc...
