Is this type of role a stepping stone to becoming a Junior Trader?

Hey all thanks for taking the time to give me some advice. I originally considered going into ibanking, but instead found myself leaning more towards a trading role at a broker/dealer. I'm a recent college graduate and received an offer for what seems like a combination of a risk/credit/operations role. Unlike banking however, the path to becoming a trader seems at least to me more confusing and nonlinear. Is this a good type of role to start out in? What do most traders do before they become traders, as they don't seem to be like ibanking and take waves of newly minted graduates at least for fully fledged trading positions. I've included the delegated responsibility for the position below. Furthermore, please forgive any incorrect assumptions about how the career path for a trader begins I'm just going off what my best guesses are as this world only came to my attention pretty recently.
