Your mission

About the Organisation & Role:

You will be part of the Core Commerce Platform organisation responsible for delivering the omnichannel commerce capabilities that power the purchase journey, inventory availability, delivery promise, order processing & fulfilment and post-purchase experiences across channels. The organisation plays a critical role in ensuring products are available to buy, orders can be fulfilled reliably, and commitments made to consumers are delivered consistently. Through a portfolio of commerce platform capabilities, the organisation enables seamless omnichannel experiences while supporting efficient, scalable, and resilient commerce operations across the global digital ecosystem.

As a Senior Software Engineer, you will design, build, and maintain production-grade backend services and omni-channel capabilities that power Basket, Cart, Pricing, Promotions, and Checkout experiences across digital commerce channels. You will work closely with Tech Leads, Product Owners, merchandising teams, and cross-functional engineering teams to deliver scalable, resilient, and low-latency commerce solutions that enable seamless customer shopping and checkout journeys.

What you will do:

• Design, develop, and maintain scalable services supporting Basket Management, Cart Operations, Pricing, Promotions, and Checkout capabilities.
• Build and enhance API-first, event-driven, and SFCC-integrated solutions that enable seamless cart experiences, real-time pricing, promotion qualification, inventory validation, and checkout orchestration.
• Support the delivery of seamless customer shopping experience and purchase experience by ensuring basket, cart, pricing, and checkout workflows operate consistently across channels, devices, and regions.
• Integrate SFCC basket and checkout services with OMS, Commerce Platforms, ERP, inventory, customer, product, and fulfillment systems to enable seamless end-to-end commerce experiences.
• Collaborate with Tech Leads and Product teams to deliver roadmap commitments.
• Drive technical design discussions and contribute to architecture decisions within the team.
• Ensure applications and services are production-ready through effective observability, monitoring, performance optimization, reliability engineering, and operational readiness practices.
• Mentor junior engineers, perform code reviews, and help establish engineering standards and best practices.
• Utilize AI-assisted engineering tools to accelerate development and strengthen code quality.
