Overview

Senior Software Engineer on the Core Commerce Platform team, building and maintaining production-grade backend payment services for digital commerce channels.

What you'll do

• Design, develop, and maintain scalable services supporting payment authorization, capture, refunds, tokenization, fraud prevention, and transaction lifecycle management across digital commerce channels.
• Build and enhance API-first, event-driven, and SFCC-integrated payment solutions, including payment gateway integrations, token management, fraud detection, and real-time payment status updates.
• Support seamless and secure customer payment experiences so 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.
• 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 observability, monitoring, performance optimization, reliability engineering, security compliance, 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.
• Support PCI-compliant payment architectures, security controls, tokenization strategies, and fraud mitigation capabilities.

What you'll need

• 7+ years of software engineering experience, with a track record of building and operating scalable, highly available, customer-facing digital commerce and payment platforms.
• Strong understanding of payment capabilities, including authorization, capture, refunds, voids, tokenization, 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 authorization, 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 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 authorization, transaction processing, tokenization, 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 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, authorization 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.
