Dev187, first I have to ask you, do you have Namibian Citizenship? If you do not, there is quite a lot of paperwork if you want to work in Namibia. They make it very difficult for citizens of foreign countries to work there, but you could apply for a work permit. If this legal stuff is not the problem, but finding the job are, I can understand your frustration. The best and most effective ways of looking for a job in Namibia is to buy the local newspapers, as this is about the only way recruiters advertise available positions in Namibia. You will probably have to ask someone in Namibia to buy this newspapers for you and mail them to you.
You will not find a lot of information on the internet. However, I would recommend that you post your CV to Namrecruit- they often have news about work in Namibia. You could also like them on facebook-then you will have first-hand info on new jobs in Namibia. Good luck.
