What's the best way to find a job in Kenya?

Hello everyone! I would like to move to Kenya, it's somewhere I have always wanted to go and I have a friend there, but I am wondering about the economy. What is the job market like and how easy is it to secure a job in Kenya? I would like to work in the NGO sector but have a range of skill sets and qualifications. Would you recommend I start looking for work before moving there or can I find work once I arrive? Any info on getting visas and work permits for Kenya would also be greatly appreciated!

Thanks in advance!
