About this role

• Build and maintain an Apollo Federation v2 subgraph that serves profile traits, audiences and personalization decisions to web, CMS and native clients, using our schema conventions, resilience patterns (timeouts, circuit breakers, kill switches, flags) and router-provided identity so a CDP failure neve...
