Looking advise

Hello everyone, I wanted to come from Ethiopia. Singapore visa is on arrival for Ethiopian citizens. So is anyone can advise me How do I get a work permit after I arrive in Singapore?  And also Can I get job easily ?

Thank you 🙏 
You can read on this forum about the available types of work visa, their requirements and which professions are in demand.

It is not possible to convert a tourist visa (which you receive on arrival) into a work visa - and a job search plus processing time for a work visa are anyway longer than your tourist visa would be valid. It is thus better you return to your country and wait for the work visa there!
@beppi thank you for your advice
