I have been working in Tanzania for 6 years and have been A Chief pilot as well.
No one will hire you from oversea, they want to see your face and your motivation as it is expensive to hire an expat.
Take a plane ticket to Dar Es Salaam and enough money to survive for a month. You should be able to find a job if you have over a 1000 hours. If not you have tried and saw a nice country.
Remenber you will need to convert your licence.
Good luck.
