A senior chief is a person who holds the enlisted (E) rank of E-8. They are one rank above Chiefs, and one below a Master Chief. Im my rate they generally serve as an SEL (senior Enlisted Leader).
A Chief Select is still a First Class (E-6) until they go through the ceremony and are actually frocked (promoted) to E-7.
Of course, like any frocking, it doesn't mean you'll actually start getting paid for the rank right away.
