HP runs one of the largest enterprise messaging and identity environments in the technology industry, spanning Microsoft Exchange (on‑premises and Exchange Online), Active Directory, Entra ID, and the directory and PKI footprint inherited through HP's acquisitions (including Poly / Plantronics). The Principal Architect, Messaging & Identity Infrastructure is the senior technical owner for this estate — driving its operation, security posture, M&A integration, and the multi‑year sunset of legacy environments such as the ATM / HPNOW Yokohama infrastructure. This is a like‑for‑like backfill for a long‑tenured Principal Architect on the Connected Digital Experiences team.

The role is hands‑on and deeply technical, with broad cross‑organizational influence across IT Operations, Information Security, GRC, and external managed‑service partners.
