Solution Architecture - HCL Commerce

Responsibilities

• Establish and maintain target and transitional architecture for a multi-tier B2B commerce environment, spanning the WCS store, business logic, Commerce tools, Spring Boot APIs, and Next.js / React storefront
• Direct the design of dual-run / strangler patterns, deciding which journeys stay on WCS versus move to Next.js and services, while safeguarding routing, session, catalog, cart, and order consistency, and setting cut-over and rollback procedures
• Produce and review solution designs, sequence/integration diagrams, and interface contracts (REST/SOAP), catching reusability, performance, security, and operability concerns prior to build
• Work closely with product, delivery leads, QA, DevOps, and enterprise/integration teams on requirements gathering, data conversion, integration testing, and cut-over execution
• Define coding and design standards across Commerce customization, Spring Boot services, and the Next.js storefront so squads stay consistent
• Steer integration with back-end systems (ERP, payments, search, CMS, punchout / customer purchasing systems), preserving a clear boundary between Preview (authoring) and Runtime (customer-facing) Commerce environments
• Evaluate designs and pull requests spanning Commerce, services, and storefront layers, and trace complex cross-layer defects back to their root cause
• Offer guidance on capacity planning, caching strategies, search, and failure handling for a high-traffic B2B storefront
• Mentor senior engineers and leads, capturing architecture decisions along with their context, options considered, and consequences to maintain continuity
• Pinpoint major obstacles and use structured problem-solving techniques to tackle complex, multi-system issues
