Senior Principal Engineer –E commerce

Job description

Job Purpose: We are seeking a Senior Principal Engineer – eCommerce to lead engineering delivery for GSK Direct, GSK's B2B eCommerce platform that enables healthcare professionals to purchase GSK vaccines and pharmaceuticals in the US and international markets. This is a hands-on engineering leadership role: you will manage the vendor technical leads and drive a multi-disciplinary DevOps team of SAP Commerce Cloud, Composable Storefront, UI, and QA engineers. The role demands deep technical expertise in SAP Commerce Cloud, headless commerce architecture, along with the ability to partner with the Business Product Owner, enterprise architecture, and business stakeholders to deliver secure, scalable, and high-impact customer experiences. Key Responsibilities: 1. Engineering Leadership & Platform Ownership Own the technical health, roadmap execution, and engineering quality of the GSKDirect-US and GSKDirect-Global eCommerce platforms built on SAP Commerce Cloud and SAP Composable Storefront. Serve as the design authority for commerce solutions, approving designs across OCC APIs, B2B commerce (company accounts, customer-specific catalogs and pricing, approvals, checkout), SSO, ERP integrations and Backoffice. Make build-vs-configure decisions that favor out-of-the-box SAP capabilities, reduce technical debt, and keep the platform upgrade-ready. Implement and enforce ITMS (IT Management System) controls, ensuring compliance, audit readiness, and operational excellence in a regulated environment. 2. Vendor Management & Delivery Oversight Manage and direct the vendor technical leads, DevOps scrum teams of SAP Commerce, Composable Storefront, UI, and QA engineers. Own sprint delivery across 3–4 week agile cycles: backlog grooming, story analysis, estimation, sprint planning, reviews, and retrospectives, and hold vendor teams accountable for quality, velocity, and commitments. Lead daily scrum with GSK leads and business stakeholders, removing blockers and making timely technical decisions. Track vendor performance against SLAs and KPIs (velocity, defect leakage, cycle time, incident resolution), and drive corrective actions and resourcing decisions with the supplier. Foster a “One Team” culture across GSK, onshore, and offshore team members built on collaboration, support, and accountability. 3. 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. That means GitHub Copilot for coding, unit tests and pull request reviews; AI help with story grooming and writing acceptance criteria; and tracking the impact on velocity and quality. Apply AI-driven monitoring to detect anomalies in site performance, checkout and order flows, cutting time to detect and resolve production issues. Plan and lead SAP Commerce Cloud and Composable Storefront/Angular version upgrades to stay current and secure. Stay ahead of SAP Commerce, composable/headless commerce, and B2B eCommerce trends, and mentor the vendor team's engineers. Prepare the platform for agentic commerce by exposing secure, well-governed OCC/REST APIs that AI agents can use, with clear guardrails for authentication, permissions and auditability. Required Qualifications: 15+ years of software engineering experience, including 6+ years building enterprise eCommerce platforms on SAP Commerce Cloud (Hybris). 5+ years leading engineering teams, including managing vendor/SI technical leads and onshore–offshore delivery models. Deep hands-on expertise in SAP Commerce Cloud: Java/J2EE, Spring, OCC APIs, ImpEx, CronJobs, Backoffice, ASM, PCM/OMS, and CCv2 deployments. Strong experience with headless commerce architecture and SAP Composable Storefront (Spartacus) on Angular (v15+), TypeScript, SSR, and front-end performance optimization. Experience delivering B2B commerce capabilities: company accounts and roles, customer-specific catalogs and pricing, approvals, checkout, order status, SSO, and ERP integration. Proven track record running agile delivery: sprint planning, estimation, backlog management, and release management with Jira, Confluence, and GitHub. Experience with CI/CD, code review practices, and production monitoring and troubleshooting (e.g., Dynatrace). Experience managing ITMS controls, security, and compliance in a regulated environment. Excellent communication and stakeholder management skills, with the ability to influence technical and business leaders. Preferred Qualifications: Experience in Pharma, Healthcare, or Life Sciences industries, ideally B2B commerce for healthcare professionals. Experience with multi-country/multi-site commerce (localization, multiple currencies and languages) and integrations with SAP S/4HANA. Hands-on experience using AI/GenAI to improve engineering productivity and digital commerce experiences (e.g., GitHub Copilot, AI-driven search and personalization, conversational commerce), in a regulated environment. #AGTech #GSK-LI Skills Application Integrations, Application Programming Interface (API) Security, Artificial Intelligence (AI), CI/CD, Cloud Engineering, Configuration Management (CM), Database Management, Data Engineering, Data Integration, Front-End Development, Internet of Things (IoT), Mobile Development, RESTful API Design, SAP Hybris, SAP Hybris B2B Commerce, Security System Design, Software Development Life Cycle (SDLC), Version Control, Web Development Why GSK?
