Walmart is a multi-national, people-led, tech-powered omnichannel retailer with over 2.2M associates.

Associate AI Experience Org is dedicated to empowering field associates, business users, and developers alike with seamless, governed AI embedded into everyday workflows to elevate productivity. We build a unified, personalized, and trusted super-agent ecosystem that transforms how work gets done. By putting intuitive agent creation tools directly into the hands of associates, our organization enables domain experts across the enterprise to seamlessly build, test, evaluate, and deploy their own grounded AI agents—connecting their team's knowledge, automating complex tasks, and driving productivity with built-in governance.

What You'll Do

Translate and co-own business problems within the data science discipline into data-driven or mathematical solutions; identify appropriate methods and tools, and demonstrate through use cases how each approach addresses the business need

Own end-to-end design, development, deployment, and operation of production AI/ML and GenAI systems, including agentic AI workflows using LangChain, LangGraph, or equivalents — enabling multi-step reasoning, tool use, planning, and autonomous task execution

Architect and operate stateful AI systems — conversation state, long-term memory, context persistence, and retrieval strategies — to support reliable, personalized, multi-turn experiences

Drive evaluation strategy for GenAI and ML systems, including offline benchmarks, online A/B experimentation, and continuous quality monitoring

Uphold and advance trustworthy AI practices: guardrails, human-in-the-loop, monitoring, governance, and safety mechanisms for agent-based systems

Identify and propose high-value AI/ML and agentic AI use cases; rapidly build MVPs and POCs to validate feasibility, performance, and impact

Select the most suitable analytical modeling techniques for structured, complex data and develop custom models; conduct EDA (statistical analysis, hypothesis testing, inference); design and run experiments; introduce new or revised features based on model responses; mentor junior associates on basic modeling and analytics techniques

Identify model evaluation metrics and apply best-practice techniques for model testing and tuning to assess accuracy, fit, validity, and robustness for multi-stage models and ensembles

Support deployment of analytical models into production at the required scale; contribute to evaluation, monitoring, and long-term sustainability of deployed models

Write production-quality code using the recommended programming languages and approved testing approach to deliver solution and application features driven by business, technical, and data requirements

Drive technical design discussions, write design documents and RFCs, and influence team-wide engineering and ML practices

Participate actively in the hiring process — conducting technical interviews, raising the bar, and advocating for diverse talent

Mentor junior data scientists and contribute to design and code reviews to raise the technical bar across the team

What You'll Bring

6+ years of professional experience designing, developing, deploying, and maintaining scalable, production-grade AI/ML and GenAI systems

Strong industry experience building production AI/ML systems, preferably at large technology companies or AI-native startups

Hands-on experience designing and deploying GenAI solutions in production, including Retrieval-Augmented Generation (RAG), advanced prompt engineering, and orchestration patterns

Working familiarity with agentic AI patterns and frameworks such as LangChain, LangGraph, or equivalent for tool-use, workflow orchestration, and multi-step reasoning

Experience managing conversational context, memory, and state — including retrieval strategies, session management, and personalization techniques

Experience driving LLM/GenAI evaluation strategy: offline benchmarks, online A/B experimentation, red-teaming, guardrails, and continuous quality monitoring

Deep foundational knowledge of statistics, classical machine learning, and deep learning, with extensive hands-on use of TensorFlow, PyTorch, or equivalent frameworks

Hands-on experience building deep learning systems, including model optimization, deployment, and performance tuning in production

Expertise in Python, with a proven track record of writing high-quality, performant, and maintainable production code

Experience with MLOps/LLMOps: CI/CD pipelines, model registries, feature stores, monitoring, drift detection, and online experimentation

Experience with containerization and orchestration tools such as Git, Docker, and Kubernetes

Working knowledge of SQL and large-scale data processing tools such as Spark, Hive, BigQuery, or equivalents

Ability to mentor junior data scientists and to collaborate with stakeholders across the organization to advocate for and implement trustworthy AI/ML practices

Strong communication skills, with experience presenting technical concepts, research findings, and product insights to technical and non-technical audiences

A research-driven, detail-oriented mindset balanced with a strong bias toward execution and real-world impact
