About the role
Job Description & Qualifications
Major Tasks, Responsibilities and Key Accountabilities
Define and maintain target and transitional architecture for multi-tier B2B commerce: WCS store, store data, business logic, Commerce tools, Spring Boot APIs, and Next.js / React storefront.
Lead design of dual-run / strangler patterns: which journeys stay on WCS, which move to Next.js + services, how routing, session, catalog, cart, and order stay consistent, and how cut-over and rollback work.
Produce and review solution designs, sequence/integration diagrams, and interface contracts (REST/SOAP). Identify re-usability, performance, security, and operability issues before build.
Partner with product, delivery leads, QA, DevOps, and enterprise/integration teams on requirements, data conversion, integration testing, and cut-over.
Set coding and design standards for Commerce customization, Spring Boot services, and Next.js storefront so squads do not fork three incompatible styles.
Guide integration with back-end systems (ERP, payments, search, CMS, punchout / customer purchasing systems) without treating Preview (authoring) and Runtime (customer-facing) Commerce as the same environment.
Review designs and PRs for Commerce, services, and storefront; unblock the hardest cross-layer defects at root cause.
Advise on capacity, caching, search, and failure modes for a high-traffic B2B storefront.
Mentor senior engineers and leads; make architecture decisions explicit (context, options, consequences) so they survive contractor turnover.
Identify key barriers and apply structured problem-solving to complex, multi-system situations.
Skills and Qualifications
Required
Bachelor's degree in Computer Science, Engineering, or related discipline, or equivalent work experience.
7+ years expertise in HCL Commerce and/or IBM WebSphere Commerce (WCS) 8.x — store customization, commands/tasks, tools, catalog/order/user/organization flows, and back-end integration. v8 experience is the hiring bar; later Commerce versions are a plus, not a substitute.
7+ years Java / J2EE and OOD on large IT systems (WebSphere Application Server strongly preferred).
5+ years Spring / Spring MVC with hands-on Spring Boot architecture (service boundaries, APIs, resilience, auth) — not “Spring on a résumé only.”
5+ years web services (REST and SOAP); ability to specify contracts others can implement.
Next.js and React production architecture experience (routing, data fetching, BFF/API integration, storefront performance). TypeScript preferred.
5+ years source control (Git required).
Experience architecting B2B commerce (punchout, org/user models, contract/pricing complexity preferred).
Experience with Agile delivery using Atlassian tools (Jira, Bitbucket/Git, Confluence).
Excellent written and verbal communication with engineers and non-engineers.
Preferred
Headless / composable commerce (API-first storefront, BFF, packaged capabilities). MuleSoft or similar iPaaS.
Search (Solr or equivalent), cache (Redis or equivalent), CMS-driven storefront (Optimizely or equivalent) alongside a commerce engine.
Cloud (GKE/Kubernetes or equivalent) for storefront and Spring Boot; WAS/IHS for Commerce.
Security, PCI-adjacent payment flows, and session/identity across legacy and modern storefronts.
Prior dual-run or large-scale commerce migration.
