Solution Architecture - HCL Commerce

We're looking for a seasonedSolution Architect with HCL Commerce expertise to drive the design and evolution of a multi-tier B2B commerce platform, steering architecture decisions across legacy Commerce systems, Spring Boot services, and modern Next.js storefronts.

Responsibilities

• Establish and maintain target and transitional architecture for multi-tier B2B commerce, covering 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 and which move to Next.js and services, while ensuring routing, session, catalog, cart, and order consistency, and establishing cut-over and rollback procedures
• Create and review solution designs, sequence/integration diagrams, and interface contracts (REST/SOAP), flagging reusability, performance, security, and operability issues before build
• Collaborate with product, delivery leads, QA, DevOps, and enterprise/integration teams on requirements, data conversion, integration testing, and cut-over activities
• Set coding and design standards for Commerce customization, Spring Boot services, and Next.js storefront to keep squads aligned
• Oversee integration with back-end systems (ERP, payments, search, CMS, punchout / customer purchasing systems), keeping a clear separation between Preview (authoring) and Runtime (customer-facing) Commerce environments
• Assess designs and pull requests across Commerce, services, and storefront layers, tracking down complex cross-layer defects to their root cause
• Provide guidance on capacity planning, caching strategies, search, and failure modes for a high-traffic B2B storefront
• Coach senior engineers and leads, and document architecture decisions with context, options, and consequences to preserve continuity
• Spot key barriers and use structured problem-solving methods for complex, multi-system challenges

Requirements

• Bachelor's degree in Computer Science, Engineering, or a related field, or comparable practical experience
• 12-20 years in professional software engineering, including at least 5 years serving as an architect or equivalent principal/staff-level designer on large-scale commerce or comparably complex multi-tier systems
• At least 8 years working with HCL Commerce and/or IBM WebSphere Commerce (WCS) 8.x, spanning store customization, commands/tasks, tools, catalog/order/user/organization flows, and back-end integration
• At least 8 years applying Java / J2EE and OOD principles on large-scale IT systems, with a strong preference for WebSphere Application Server experience
• At least 5 years working with Spring / Spring MVC and hands-on Spring Boot architecture, including service boundaries, APIs, resilience, and authentication
• At least 5 years designing web services (REST and SOAP), with the ability to specify contracts for other teams to build against
• Hands-on production architecture experience with Next.js and React, including routing, data fetching, BFF/API integration, and storefront performance, with TypeScript knowledge preferred
• At least 5 years using source control, with Git experience required
• Preferred background in architecting B2B commerce solutions, including punchout, org/user models, and contract/pricing complexity
• Experience delivering in Agile environments using Atlassian tools (Jira, Bitbucket/Git, Confluence)
• Strong written and verbal communication skills for engaging both technical and non-technical stakeholders

Nice to have

• Familiarity with headless/composable commerce concepts (API-first storefront, BFF, packaged capabilities) and iPaaS tools such as MuleSoft
• Exposure to search platforms (Solr or similar), caching solutions (Redis or similar), and CMS-driven storefronts (Optimizely or similar) working alongside a commerce engine
• Hands-on experience with cloud platforms (GKE/Kubernetes or equivalent) for storefront and Spring Boot deployments, plus WAS/IHS for Commerce
• Solid grasp of security practices, PCI-adjacent payment flows, and session/identity management spanning legacy and modern storefronts
• Prior involvement in dual-run initiatives or large-scale commerce migration efforts
