What you'll bring:
· Bachelor’s degree in Computer Science, Engineering, or a closely related technical discipline. · 13+ years of progressive software engineering and architecture experience, including significant technical leadership across large-scale, business-critical platforms. · Deep experience architecting and operating highly scalable distributed systems supporting high-volume digital customer experiences and transaction workloads. · Demonstrated experience defining enterprise-scale architecture strategies, North Star architectures, and multi-year platform modernization roadmaps. · Deep expertise across modern distributed architectures, microservices, APIs, event-driven systems, cloud platforms, caching, distributed data systems, messaging, observability, and highly available application architectures. · Strong understanding of distributed transaction patterns, consistency, idempotency, failure recovery, fault isolation, resiliency, and high-availability architecture. · Experience architecting high-performance customer-facing platforms where latency, availability, scalability, reliability, and customer experience are critical. · Strong understanding of modern commerce and transaction journeys, including Cart, Checkout, payments, tendering, pricing, promotions, inventory, fulfillment, ordering, and the broader purchase lifecycle. · Proven experience simplifying and modernizing large, complex technology ecosystems while maintaining business continuity. · Strong track record of solving systemic technical challenges spanning multiple teams, platforms, and organizational boundaries. · Demonstrated ability to establish architecture principles and technical standards that improve consistency while enabling engineering teams to innovate independently. · Strong experience driving operational excellence through architecture, including platform resilience, observability, performance optimization, capacity planning, fault isolation, disaster recovery, and engineering quality. · Experience leveraging AI, automation, developer platforms, and modern software engineering practices to improve engineering productivity and accelerate delivery. · Ability to connect architecture and technology investments with measurable customer and business outcomes including conversion, revenue, customer experience, reliability, and engineering efficiency. · Proven ability to influence senior Engineering, Product, Business, and Platform leaders and drive alignment around complex architectural decisions. · Demonstrated technical leadership and mentorship of Principal Engineers, architects, and other senior engineering talent. · Exceptional communication and influencing skills, with the ability to simplify complex technical problems and articulate architectural strategies to both technical and executive audiences.
Business & Engineering Outcomes In this role, you will drive measurable architectural and engineering outcomes across Transactions, Cart & Checkout, including:
- Establish and drive adoption of a North Star architecture for Cart, Checkout, Payments, and transaction platforms, creating clear domain boundaries and a scalable foundation for the long-term evolution of the purchase journey.
- Reduce architectural complexity and systemic technical debt by simplifying service interactions, eliminating unnecessary dependencies, rationalizing overlapping capabilities, and establishing well-defined platform contracts.
- Increase architecture reuse and leverage through standardized APIs, event patterns, data contracts, reusable transaction capabilities, and common platform patterns that enable teams to build and integrate capabilities faster.
