Julie Glynn, who spent the last 13 years in-house at JPMorgan Chase & Co., is rejoining the brokerage industry’s main watchdog as a senior enforcement official, a newly created role where she will serve as a senior adviser to enforcement head Bill St. Louis.

Glynn also will oversee four chief counsel enforcement teams as well as enforcement litigation, the Washington, D.C.-based Financial Industry Regulatory Authority said this week. She will start in September.
