@The Pentacle Queen,
Lecturer?
Well, here, you have to go to a university, get a good degree, a good Masters, and be working towards your Phd.
They often let you tutor during that process....you ought also be looking to get papers published.
Then, when you have a good Phd, they may let you do some sessional lectures while you publish more.
Often, you spend years on various contracts while you do as much research and publish as much as you can.
Sometimes you get a offered permanant lectureship after a while.
