• 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

• At least 8 years of experience in Java / J2EE and object-oriented design on large IT systems, with a strong preference for WebSphere Application Server background
• At least 5 years working with Spring / Spring MVC, with hands-on experience architecting Spring Boot solutions, including service boundaries, APIs, resilience, and authentication
• At least 5 years working with REST and SOAP web services, with the capability to define contracts for other teams to build against
• Hands-on production architecture experience with Next.js and React, covering routing, data fetching, BFF/API integration, and storefront performance, with TypeScript knowledge preferred
• At least 5 years using source control systems, with required Git proficiency
• Preferred background in designing B2B commerce architecture, including punchout functionality, organizational/user models, and contract/pricing complexity
• Familiarity with Agile delivery methods using Atlassian tooling (Jira, Bitbucket/Git, Confluence)
• Strong written and verbal communication abilities suited to both technical and non-technical audiences
• Nice to have Familiarity with headless/composable commerce concepts (API-first storefronts, BFF, packaged capabilities) and MuleSoft or comparable iPaaS platforms
• Exposure to search technologies (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 similar) for storefront and Spring Boot deployment, plus WAS/IHS knowledge for Commerce
