Staff, Software Engineer - Full Stack

About the role

Position Summary... Join Walmart Global Tech as a Staff Software Engineer and become the technical backbone of our cross-border commerce platform. In this role within our Growth Tech Marketplace organization, you'll design cross-service architectures, set engineering standards across squads, and translate complex business challenges into scalable, production-grade systems that power international trade at Walmart scale.

About Team: Our team creates reusable technologies to help with customer acquisition, onboarding, and empowering merchants, while ensuring a seamless experience for both of these stakeholders. We also optimize tariffs and assortment in accordance with Walmart's Everyday Low Cost philosophy. We not only create affordability, but we also deliver customized experiences for customers across all channels - in-store, mobile app, and websites.

What you'll do... Lead Cross-Service Architecture & System Design Own the end-to-end technical design of cross-border trade systems — including seller onboarding, order orchestration, compliance, and payments infrastructure — establishing reusable architectural patterns across multiple squads that are reliable, observable, and built to scale globally. Set and Enforce Engineering Standards Define and drive adoption of coding standards, testing practices, SDLC compliance (SonarQube, Snyk, Gatekeeper quality gates), and API design principles across CBT engineering teams — raising the collective bar through documentation, design reviews, and active mentorship. Partner with Product & Engineering Leadership on Technical Feasibility Collaborate with PMs and Engineering Managers to assess roadmap feasibility, surface technical risks early, and guide build-vs-buy-vs-partner decisions — translating ambiguous business requirements into well-scoped, executable engineering plans. Own Non-Functional Requirements & Production Readiness Lead production readiness reviews; define and own SLOs/SLAs for critical cross-border services; drive observability, incident response preparedness, and capacity planning across the platform to ensure resilience and uptime at Walmart scale. Mentor Senior Engineers & Drive a High-Performance Engineering Culture Actively mentor and grow Senior Software Engineers (L5); lead architecture working groups and communities of practice; champion AI-augmented development (Wibey, GitHub Copilot) as a team multiplier within CBT squads.

What you'll bring:

Distributed Systems & Cloud-Native Architecture Expertise Deep, hands-on experience designing and operating scalable, fault-tolerant distributed systems — microservices, event-driven architecture, message queuing, and cloud-native platforms (Kubernetes/WCNP, GCP/Azure) — ideally in e-commerce or marketplace environments. System Thinking Across Service Boundaries Ability to reason across multiple services and teams simultaneously — identifying cross-cutting concerns (shared data models, consistency guarantees, API contracts, observability) and making holistic design decisions that improve the Technical Leadership & Multi-Squad Influence Track record of driving technical alignment across multiple squads without direct authority — through strong communication, credibility, and the ability to build consensus on engineering standards, architectural decisions, and delivery trade-offs. Commerce Domain Knowledge Working familiarity with e-commerce or marketplace platform challenges — seller integrations, order lifecycle management, international compliance, multi-currency handling, and cross-border logistics — enabling sound, domain-aware architectural decision Operational Excellence & Reliability Mindset Strong orientation toward production quality — experience owning SLOs, leading incident retrospectives, building observability into system design (metrics, logging, tracing), and proactively addressing technical debt before it becomes customer impact.
