The Role
IonQ is scaling rapidly across geographies, functions, and acquisitions. As a result, data is increasingly fragmented across systems, teams, and entities. We are hiring a Chief Data Officer to establish the IT-enabled data foundation, architecture, integration patterns, cataloging, and governance workflows needed to make data cohesive, trusted, secure, and usable across existing functional data domains. This role operates horizontally across the organization, partnering with Finance, GTM, HR, IT, Architecture, Security, and Product teams to ensure data is consistent, secure, and usable—without displacing functional ownership. Functions remain accountable for the business meaning, quality, rules, and use of their data; this role provides the enterprise data architecture, methodology, tooling, and integration support to make that data usable across IonQ.

- Maintain an enterprise registry of authoritative data sources, key data owners, major data flows, dependencies, and downstream reporting / analytics uses
