Senior Software Engineer - Core Commerce Platform

Sits within the Core Commerce Platform organisation, which delivers omnichannel commerce capabilities that power the purchase journey, inventory availability, delivery promise, order processing and fulfilment, and post-purchase experiences across channels. The organisation ensures products are available to buy, orders can be fulfilled reliably, and commitments made to consumers are delivered consistently through scalable, resilient commerce operations. The role designs, builds, and maintains production-grade backend services for payment capabilities, including payment processing, authorisation, tokenisation, fraud prevention, and transaction orchestration across digital commerce channels.

• Design, develop, and maintain scalable services supporting payment authorisation, capture, refunds, tokenisation, fraud prevention, and transaction lifecycle management across digital commerce channels.
• Build and enhance API-first, event-driven, and SFCC-integrated payment solutions that enable secure transaction processing, payment gateway integrations, token management, fraud detection, and real-time payment status updates.
• Support the delivery of seamless and secure customer payment experiences by ensuring payment workflows operate consistently across channels, devices, regions, and currencies.
• Integrate SFCC payment services with payment gateways, PSPs, OMS, ERP, fraud platforms, tax services, customer systems, and other enterprise applications to enable seamless end-to-end payment processing.
• Collaborate with Tech Leads, Product teams, and payment partners 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 optimisation, reliability engineering, security compliance, and operational readiness practices.
• Mentor junior engineers, perform code reviews, and help establish engineering standards and best practices.
• Utilise AI-assisted engineering tools to accelerate development and strengthen code quality.
• Support PCI-compliant payment architectures, security controls, tokenisation strategies, and fraud mitigation capabilities to protect customer transactions and sensitive payment data.

• 7+ years of software engineering experience, with a strong track record of building and operating scalable, highly available, customer-facing digital commerce and payment platforms.
• Strong understanding of payment capabilities, including payment authorisation, capture, refunds, voids, tokenisation, payment instruments, and transaction lifecycle management.
• Strong understanding of design patterns, data structures and algorithms, with practical experience applying them to real-world use cases.
• Solid knowledge of payment processing workflows, including payment authorisation, settlement, refunds, partial captures, chargebacks, token management, and transaction reconciliation.
• Expertise in backend engineering, API design, microservices, event-driven architectures, and scalable integration patterns using Java, Spring Boot and related frameworks.
• Familiarity with Payment Service Providers (PSPs) and payment gateway integrations such as Adyen, Cybersource, Stripe, Worldpay, PayPal, or equivalent enterprise payment solutions.
• Strong hands-on software engineering experience with modern microservices architectures using Java and Spring Boot.
• Experience designing and building high-throughput, low-latency services supporting payment authorisation, transaction processing, tokenisation, refunds, fraud checks, and settlement workflows.
• Experience with performance engineering, load testing, and capacity planning for mission-critical payment services, particularly during peak sales events and seasonal trading periods.
• Experience designing graceful degradation and fallback mechanisms that help sustain payment processing continuity during third-party provider outages or downstream system disruptions.
• Strong observability and operational excellence practices, including monitoring, distributed tracing, alerting, log analysis, and root-cause analysis for payment failures, authorisation latency, transaction declines, settlement issues, and fraud alerts.
• Strong ability to mentor engineers, review payment integration designs, conduct code reviews, and drive sound technical decisions and engineering standards.
• Experience using coding agents, LLMs, or AI-assisted engineering tools to improve software delivery, testing, code quality, and developer productivity.
