Yes. I imagine you are aware that this sentence sounds chatty. It sounds like creative writing - perhaps a personal bio or short story, rather than a formal letter. It probably sounds this way because it is round about, rather than straight to the point. I would also add 'In fact I became an employee' or 'On the contrary, I became an employee...'. But this is all to do with personal preference and style. Linguistically I believe your sentence is fine.
