Distinguished, Software Engineer

Position Summary...

What you'll do...

We are seeking a seasoned Distinguished, Software Engineer - Site Engineering Architect to lead the technical architecture and cross-functional delivery for our eCommerce site platforms. In this role you will own the architecture, operational model, and engineering standards that enable highly available, secure, performant, and extensible eCommerce experiences. You will partner closely with engineering, product, UX, operations and business stakeholders to define technical strategy, drive execution for large-scale initiatives (including next-generation eCommerce platform work), and continuously improve how we design, deliver and operate solutions.

This role combines deep hands-on architectural leadership with program-level influence: you will design and validate solutions, unblock engineering teams, and lead improvements to the processes and observability that govern site reliability, performance, and compliance.

About the Team:

We are the Site Engineering team responsible for designing, building and operating the WCP (Walmart Commerce Platform) stack - the unified technical foundation that powers Walmart's customer-facing sites and experiences. Working hand-in-hand with Walmart U.S. stores, eCommerce, mobile teams, Merchants, and Operations, we deliver end-to-end site engineering solutions that serve Walmart U.S., International, and Sam's Club markets. Our work empowers team members, stores and merchants with scalable, secure, and highly available technology across online, mobile and in-store channels.

Our focus areas include customer and store experiences, in-store service enablement, merchant tools and merchant data science, and search & personalization. As the site engineering team, we own platform architecture, performance, observability and operational playbooks that let product, UX and business teams move quickly while maintaining reliability, compliance and excellent customer outcomes across all markets.

* What you'll do:

* Lead architecture and technical strategy for core eCommerce site platforms (catalog, search, checkout, cart, personalization, promotions, storefront, content delivery), ensuring scalability, availability, security and extensibility.

* Shape and improve program delivery processes: roadmaps, planning cadences, risk frameworks, release gating, change control and cross-team dependency management to increase predictability and throughput.

* Design and implement observability, monitoring and alerting patterns (metrics, tracing, logs, synthetic monitoring, SLIs/SLOs) to reliably measure site health and customer impact; create runbooks and operational playbooks.

* Partner with SRE/ops to lead capacity planning, performance tuning, cost optimization and incident response improvements for site reliability and customer experience.

* Mentor and coach technical leads and engineers on system design, performance engineering, and trade-off analysis.

* Evaluate new technologies and third-party suppliers (search providers, payment gateways, CDNs, personalization engines) and drive technical due diligence and proof-of-concepts.

* Ensure engineering work complies with regulatory/security standards (PCI-DSS, GDPR, internal security policies) and auditability requirements.

* Communicate architecture and program status clearly to senior leadership and influence roadmap and investment decisions.
