xAI adds a "Combo Welder - Memphis" Data Center role, drops the "Member of Technical Staff" prefix from several Model and Engineering titles, and closes a Sales role

One Data Center posting in Southaven, MS; Memphis, TN is a single hire, not a buildout cluster; the retitles (e.g. "RL Inference", "Post-Training and RL") are wording churn, and the "GCR Agency Development Manager" removal in Singapore is one role.
