Subject: What is the levels of genetists and what does each job consist of?

I am writing a story ( a long one) on the assent of a Genetist. I was wondering
if there are typical "levels" one must ascend through such as Lab assistant or
Lab technician. The Scientist in question ends up the head of a lab working on
genetically enhancing humans using (fictional) radioactive materials. This does
not have to be any sort of in-depth thing; a quick list would be very helpful in
letting me look up each individual job.
