**Req ID:** 387047 NTT DATA strives to hire exceptional, innovative and passionate individuals who want to grow with us. If you want to be part of an inclusive, adaptable, and forward\-thinking organization, apply now. We are currently seeking a Principal Commerce Layer Architect \- REMOTE to join our team in Dallas, Texas (US\-TX), United States (US). We are seeking an enterprise\-level Principal 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 CommerceLayer. 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. Key Performance Responsibilities Enterprise Architecture, Design Discovery * Author and maintain comprehensive architectural blueprints, sequence diagrams, and data\-flow mappings detailing how CommerceLayer 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. System Scalability, Stability Co\-existence Governance * 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 CommerceLayer 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. Technical Governance Cross\-Functional Collaboration * 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.
