Hands-on SAP Commerce Cloud & Headless Commerce Expertise • Provide technical direction on SAP Commerce Cloud environment management and deployments. • Guide the headless storefront architecture on SAP Composable Storefront (Spartacus) and Angular, including SSR, lazy loading, performance optimization, accessibility, and reusable component and design-system patterns. • Lead code quality through GitHub pull request reviews, coding standards, unit testing expectations, and secure development practices. • Drive root cause analysis of complex production issues. 4. Strategic Partnerships & Business Alignment • Partner with the GSK Business Product Owner and business stakeholders in the US and global markets to translate commercial needs into scalable technical solutions and a prioritized roadmap. • Align with enterprise architecture, security, and integration teams (ERP, identity, data) within a federated architecture model. • Influence roadmap and investment decisions by providing technical insights, feasibility assessments, and effort estimates, and explain technical trade-offs in clear, non-technical language. 5. Innovation & Continuous Improvement • Modernize engineering practices: CI/CD pipelines (GitHub, Jenkins, Azure DevOps), test automation, release management, and environment strategy on CCv2. • Drive AI-assisted engineering across the vendor DevOps team.
