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 that power Inventory, Promise & Order Fulfilment capabilities. You will work closely with Tech Leads, Product Owners, and Data Engineering teams to deliver reliable, scalable, and low-latency services. You will actively contribute to design decisions, code reviews and mentor junior engineers in the team.

What you will do:

• Design and operate secure, observable and resilient Java/Spring Boot services and low-latency APIs for inventory availability and order promising with performance suitable for peak and concurrent demand

• Implement robust concurrency-control and consistency patterns to prevent overselling when multiple orders compete for limited inventory.

• Build event-driven inventory processing using Kafka or similar messaging technologies to handle receipts, adjustments, reservations, releases, cancellations, and fulfilment updates in near real time.

• Integrate inventory and promising services with OMS, commerce, WMS, ERP, store, and fulfilment platforms to provide consistent availability across the order lifecycle.

• Independently own complex services or components from technical design through production.

• Write clean, tested and maintainable code, participate in peer reviews, and maintain relevant technical documentation.

• Optimize performance, scalability, reliability, and operational efficiency through automation and proactive improvements. 

• Support production services through monitoring, troubleshooting and root-cause analysis contributing to reliability improvements.

• Lead component-level design, document trade-offs and contribute recommendations to team-level architecture decisions.

• Mentor junior engineers, perform code reviews and help establish engineering standards and best practices.

• Bachelor's degree in computer science, Information Technology, Engineering, or a related field.

• 7+ years of software engineering experience, with a strong track record of building and operating scalable, high-availability, consumer-facing platforms.

• Strong hands-on software engineering experience with Java, Spring Boot, and modern microservices architectures, building scalable, resilient, and production-grade services.

• Strong understanding of design patterns, data structures and algorithms, with practical experience applying them to real-world use cases.

• Hands-on experience with Kafka or similar event-streaming platforms for event-driven architectures, asynchronous processing, and enterprise-scale system integrations.

• Deep understanding of caching strategies and hands-on experience with Redis or equivalent technologies.

• Strong understanding of concurrency, consistency, and transactional integrity patterns required to prevent overselling in distributed commerce environments.

• Experience implementing event-driven architectures and designing resilient solutions that maintain accuracy under peak trading and high-volume conditions.

• Experience designing graceful degradation and fallback mechanisms that ensure continuity of commerce operations during downstream system disruptions.

• Strong experience with observability and operational excellence practices, including monitoring, distributed tracing and alerting.

• Understanding of inventory management concepts, order promising and delivery estimation models, including inventory location, fulfilment capacity, carrier constraints, and service-level commitments is highly desirable.

• Experience configuring, customizing, and extending OMS platform capabilities to support complex business requirements and omnichannel commerce use cases is preferred.

• Hands-on experience integrating or configuring Fluent Commerce or a comparable OMS platform such as IBM Sterling OMS, Manhattan Associates, Kibo, Salesforce OMS, or similar technologies will be an advantage.

• Experience using coding agents, LLMs or AI-assisted engineering tools to improve software delivery and developer productivity.
