Within the same company? Money, that's about it. Between companies there is no standardization of levels, titles, and responsibilities.

Fun fact: at IBM a "Staff" is actually junior to a "Senior". So it's all over the place anyway.

The latest trend in new companies is to not assign named titles at all, just numbered levels.
