Staff, Software Engineer - GenAi

Position

Summary

... What you'll do... We're hiring a   Staff Software Engineer   to pioneer this frontier—not building foundation models from scratch, but   expertly integrating GenAI and LLMs into production e-commerce systems   that scale to   billions of interactions.

If you're passionate about transforming cutting-edge AI from prototypes into real-world impact, influencing architectures across teams, and   s hipping features that redefine global shopping—let's connect.

About You

• You   live for code that drives real impact . You thrive in   JavaScript, Node.js, and GraphQL , embracing JS's quirks while crafting clean, functional, and shippable masterpieces. But now, you're thrilled to overlay   GenAI —building intelligent frontends and services that pulse with life.
• You   obsess over AI-powered UX that wows . You don't just code pixels; you design experiences where   AI anticipates, delights, and empowers users —fusing creativity, empathy, and technical precision.
• You're a   relentless learner , diving deep into emerging tech like   LLMs, agents, RAG, and evaluation frameworks , and turning research into production magic—whether orchestrating frontends, integrating backends, or creating full-stack AI flows.
• You   master scale with finesse : Handling performance on unpredictable networks,   A/B testing AI variants , implementing   safety/quality guardrails , and navigating rapid ecosystem shifts—all while shipping fast and boldly.
• You   amplify teams : Mentoring peers, building shared   AI tooling , contributing to open-source where it fits, and elevating everyone in the   GenAI era .

What You'll Do

As a   Staff Software Engineer   in   Walmart International, you'll shape   AI-driven shopping   across diverse markets:

• Define and drive technical strategy   for   GenAI-powered experiences —architect scalable frontend/backend solutions that integrate   LLMs   intelligently, ensuring   rock-solid code quality, performance, security, and observability .
• Lead development of AI-infused features —craft   React UIs   with intelligent components, manage state in dynamic AI contexts ( Redux + React Query ), and build efficient   GraphQL APIs   as the backbone for LLM-powered services.
• Ship and optimize GenAI/LLM features at massive scale —design APIs and service architectures that seamlessly blend   AI/ML components , manage   token costs, latency, and safety , and deliver   measurable delight to millions .
• Refactor and evolve codebases —making them modular, maintainable, and primed for the next wave of   AI innovation .
• Collaborate cross-functionally —with product, design, UX, backend, and   AI research teams —to craft cohesive, magical customer experiences.
• Build internal AI best practices —create reusable tooling,   evaluation frameworks , coding standards, and documentation to accelerate the entire organization.
• Mentor and influence —lead code reviews, guide engineers, drive developer productivity initiatives, and shape technical direction through   expertise, collaboration, and vision .
• Push boundaries —experiment with emerging   GenAI techniques , share insights internally (and externally when possible), and own large-scale projects impacting   global e-commerce daily .

What You'll Bring

• 10+ years of software engineering experience   building and shipping large-scale, production systems.
• Proven track record   shipping distributed systems in   Java   (or equivalent high-scale languages).
• Hands-on experience   shipping   GenAI or LLM-powered features/services   as part of larger production systems.
• Strong experience   designing   APIs and service architectures   that integrate with   AI/ML components .
• Deep expertise   in modern   JavaScript ecosystems   ( React, Node.js, GraphQL ) and   performance optimization, testing, CI/CD .
• Demonstrated ability   to influence technical direction without direct authority—through expertise, collaboration, and vision.

Preferred Qualifications

• Expertise with GenAI tools/patterns   (e.g.,   RAG, agents, prompt orchestration, evaluation pipelines ).
• Experience operationalizing LLM evaluation frameworks —including offline benchmarks, automated + human review loops, production monitoring for   quality, safety, and business impact   (nice to have, but highly valued).
• Familiarity with cloud platforms   ( AWS/GCP/Azure ),   containerization   ( Docker/Kubernetes ), and   microfrontends/monorepos   ( Nx ).
• Track record in Agile environments   with excellent communication skills.
