Enterprise Architect

Your Tasks

Define and evolve the target architecture for Customer Retention (B2C & B2B), Marketing, Loyalty, and Customer Care across all channels (web, app, store, contact center).

Design end-to-end customer data flows and canonical models to enable a unified customer 360, golden record, and seamless identity across systems.

Architect integrations between various CRM systems & components, Customer Data Platform, marketing automation/orchestration, loyalty platform, POS, e-commerce, and analytics—leveraging APIs and event-driven patterns.

Establish and govern API, event, and data standards (naming, versioning, schemas, security) and drive their adoption across product teams.

Shape non-functional architecture to support peak retail volumes (e.g., product launches, seasonal peaks): scalability, availability, resilience, observability, and security-by-design.

Partner with business stakeholders in CRM, Marketing and Loyalty to translate strategies and requirements into actionable roadmaps and solution designs.

Provide architectural guidance throughout delivery lifecycles—discovery, design, implementation, testing, deployment, and hyper care—reviewing designs and code for customer-domain components (APIs, events, data pipelines).

Implement data governance practices for consent and preference management, privacy compliance, data quality, deduplication/matching, anti-fraud and sanctions compliance.

Contribute to capability mapping, portfolio rationalization, and build-vs-buy decisions; produce reference architectures, standards, and decision records.
