The expression "cut your teeth on something" means to gain experience by doing something. It usually refers to a situation where someone has just started a new job or activity and they are learning how to do it. For example, if someone is a new teacher, they might "cut their teeth" by teaching a few classes and gaining experience from those. It's like when a baby is teething and they use their new teeth to learn how to eat and chew new foods. So, if someone says "I cut my teeth on that job," they mean that they gained experience and learned how to do their job well by doing it.
