Where does JL 4A lies in hirearchy of Infosys

My friend having 13 YoE in copywriting (previously worked in ad agencies) has gotten an offer from infy. She is being offer JL4A with designation - Senior Process Lead.

Not sure if this would be a IC or TL position but want to know where does this lies on overall career or job level. Is this usual for folks having 10+ YoE to work at JL4?
