· 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
