Lead Java Full Stack Engineer

JD:

• Bachelor's degree in Computer Science, Engineering, or related discipline, or equivalent work experience.

• 10+ years professional software engineering; 5+ years in an architect or equivalent principal/staff design role on large commerce or similarly complex multi-tier systems.

• 8+ 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.

• 8+ 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.
