Sr. SAP Commerce Platform Engineer

This role is a senior-level, hands-on backend engineering position focused on building and evolving a centralized SAP Commerce platform that supports multiple brand storefronts. The engineer is responsible for designing and developing custom SAP Commerce extensions, integrating the platform with enterprise systems (such as ERP, PIM, and CRM), and owning issues end-to-end—from storefront requests through backend services to integration layers. A major expectation is independent troubleshooting using tools like SAP Commerce Cloud logs and Dynatrace to diagnose and resolve production issues at the root. The role also involves shaping API design in a headless/composable architecture, contributing to system design and delivery planning, and elevating team capability through code reviews, documentation, and technical leadership. Strong backend expertise, integration experience, and the ability to operate autonomously across the full stack are critical for success. **Legrand North America** has a remote opportunity for a **Senior SAP Commerce Platform Engineer** to join our Enterprise Digital Systems team. **This is a deep platform engineering role (not a maintenance role).** You will build and extend the SAP Commerce backend, integrate it with upstream enterprise systems through middleware, and own problems end to end — from the storefront request down through the service and persistence layers to the integration boundary. The platform serves multiple brands and storefronts and is evolving toward a composable, headless architecture, so your work at the core is consumed by every team that builds on top of it. We are seeking engineer who can operate independently inside the platform: reason through the full stack, diagnose production issues by working directly through SAP Commerce and Dynatrace logs, and resolve them at the root. **At a Glance** - Work inside a centralized SAP Commerce backend that powers multiple brand storefronts. Some storefronts are owned by the platform team; others are owned by business-unit teams who consume what you build. Decisions you make in the core propagate outward to all of them. - Hands-on backend engineering: building and maintaining custom SAP Commerce extensions — type system, service layer, interceptors, cron jobs, ImpEx, integration logic — and on the integrations that connect commerce to upstream enterprise systems (ERP, PIM/Stibo, CRM) through middleware. - Independent troubleshooting through SAP Commerce Cloud and Dynatrace is a daily expectation. You should be the person who can take an ambiguous production symptom and trace it through logs, traces, and code to a root cause without escalation. - The platform is moving toward headless / composable (OCC APIs, headless content, search). Sound API and contract judgment matters and is valued — but it sits on top of, and depends on, real depth in the backend itself. - This role reports into Platform Engineering and partners with the platform architect on design and estimate validation. You'll be expected to operate with independent technical direction and full ownership of outcomes in your domain. ### Responsibilities **Build and extend the SAP Commerce backend** - Design, build, and maintain custom SAP Commerce extensions — data models, service layer, facades, interceptors, cron jobs, and platform logic — following sound architecture for a multi-brand, multi-storefront environment. - Work fluently across the SAP Commerce stack: type system and persistence, the Spring-based service layer, ImpEx, FlexibleSearch, and the build/deploy model on Commerce Cloud. - Develop new platform capabilities against business requirements, and maintain and refactor the existing codebase, including the accelerator-based storefront that runs today. **Integrate with upstream systems** - Build and maintain integrations between SAP Commerce and upstream enterprise systems (ERP, PIM/Stibo, CRM) — through middleware where appropriate — using standard, resilient integration…
