E-Commerce​/Commerce Layer Architect - REMOTE

Req : 387047. NTT DATA strives to hire exceptional, innovative and passionate individuals who want to grow with us. We are currently seeking a E-Commerce / Commerce Layer Architect - REMOTE to join our team in Dallas, Texas (US-TX), United States (US). We are seeking an enterprise-level Commerce Layer Architect to own, design, and govern the technical blueprint of our global digital commerce ecosystem.

In this high-seniority role, you will be the core technical authority responsible for transitioning legacy architectures into a highly decoupled, API-first, composable infrastructure powered by Commerce Layer. You will orchestrate the intersection of high-scale checkout operations, globally distributed inventory pools, complex multi-market pricing engines, and enterprise data flows. Working directly with executive stakeholders, engineering managers, and cross-functional product teams, you will establish the integration patterns, performance benchmarks, and governance standards that safeguard our global transaction layers.

• Author and maintain comprehensive architectural blueprints, sequence diagrams, and data-flow mappings detailing how Commerce Layer communicates with external PIM, ERP, and OMS infrastructure.
• Design robust structural guardrails, caching strategies, and edge computation models to maximize API efficiency and ensure low-latency storefront interactions globally.
• Resolve highly complex engineering bottlenecks, structural performance regressions, and multi-region synchronization failures across the composable layer.

• Define and audit end-to-end security parameters across the transaction pipeline, including encryption of sensitive customer records, API access token lifecycle management, and verification of webhook signatures.
• Establish architectural strategies for phase-based rollouts, allowing localized markets to go live independently on Commerce Layer while legacy commerce properties gracefully deprecate.
• Formulate robust automated load-testing and regression strategies to guarantee that core ordering pathways remain unbroken during massive seasonal traffic surges.

• Lead complex architectural discovery workshops, technical steering committees, and system-readiness evaluations to align data, frontend, infrastructure, and QA teams.
• Provide high-fidelity engineering complexity assessments, technical risk logs, and resource forecasting matrices for the long-term technology roadmap.
• Maintain elite developer documentation, tracking system interface contracts, integration fallback procedures, and emergency infrastructure runbooks.

• Composable Commerce layer Schema & Core Resource Modeling
• Focus Areas:
  Designing enterprise-grade data schemas utilizing the Commerce Layer JSON:
  
  API specification; establishing relationships between core primitives (Markets, Promotion Rules, Stock Locations, Shipping Methods, SKUs, and Price Lists); and structuring multi-tenant or multi-organization work spaces to support localized international brand portfolios.
• Multi-Market Inventory & Global Supply Chain Routing Architecture
• Focus Areas:
  Engineering real-time inventory allocation logic using Commerce Layer Inventory Pools and Stock Locations; designing fallback rules for distributed warehouse systems; and syncing high-velocity stock updates from external ERP/WMS nodes without triggering API rate limits or processing bottlenecks.
• Enterprise Cart, Multi-Currency Pricing & Secure Checkout Flows
• Focus Areas:
  Architecting localized pricing matrix architectures across hundreds of distinct localized markets; orchestrating PCI-compliant checkout flows; integrating headless payment gateways (Stripe, Adyen); and binding real-time tax calculation engines (Avalara, Tax Jar) securely into the Commerce Layer Order model.
• Event-Driven Webhooks, Subscriptions & Async Integration Patterns
• Focus Areas:
  Designing event-driven decoupled systems using Commerce Layer Webhooks and Circuit Breakers; building…
