Responsibilities
- Unified Customer Profile: Architect and build the systems that create a unified customer profile by resolving fragmented identifiers across systems and managing contact data, consent, and channel preferences at global scale.
- Event Ingestion and Real Time Data Pipelines: Architect high-throughput ingestion pipelines (hundreds of millions of events/day across 11+ markets) that unify behavioral, transactional, and third-party signals into enriched profiles powering ML, segmentation, and activation.

- Messaging Infrastructure Consolidation: Lead the technical strategy and execution for consolidating a fragmented messaging vendor ecosystem, designing migration paths and platform abstractions that allow teams to transition without disrupting live operations.
- Internal Platform APIs: Design and maintain the developer-facing APIs and platform services that enable teams to send messages through a unified communications platform with clear contracts, versioning, and operational reliability.
