Our team is driving high-impact enterprise initiatives, including recommendation platforms, customer voice, market research, product innovation, customer attitudinal segmentation, agent based simulations, and many more. These initiatives require advanced expertise in GenAI & Agentic AI Innovation. Architect and build agentic AI systems with capabilities such as planning, memory, tool-use, and multi-agent collaboration, ensuring seamless integration with Walmart’s digital ecosystem. Define best practices for LLMOps, including prompt versioning, embedding store management, synthetic data generation, fine-tuning strategies, and continuous evaluation for safety, accuracy, and bias. Drive applied research in large language models (LLMs) and multi-modal AI, leveraging methods such as LoRA/PEFT fine-tuning, reinforcement learning from human feedback (RLHF/DPO), quantization, and speculative decoding. Explore and operationalize RAG pipelines, deep research, multimodal fusion, and specialized architectures for language, vision, time series, and beyond. Translate ambiguous, high-impact business problems into scalable AI/ML solutions with measurable outcomes. Build and guide end-to-end ML systems covering data sourcing, feature engineering, model training, deployment, monitoring, and iteration. Champion advanced MLOps practices: automated pipelines, CI/CD for ML, model versioning, drift detection, and telemetry-based monitoring. Ensure models meet standards of fairness, explainability, and responsible AI compliance. Serve as a technical leader and mentor, guiding senior engineers and applied scientists to build depth and expertise. Influence cross-functional platform strategy, ensuring AI systems align with Walmart’s broader product and engineering vision. Contribute to Walmart’s AI reputation through thought leadership—publishing, presenting, and showcasing innovations internally and externally.
What We’re Looking For Above all, we're looking for a leader defined by curiosity and the resilience to thrive in complex, innovative, and high-uncertainty environments. The ideal Principal has a deep technical science and engineering background—mastery of algorithmic thinking and strong coding skills—even if they haven't mastered every agentic technology on day one. We value the efficient use of AI coding assistants but expect strong, independent coding prowess. Your willingness to work hard and quickly get up to speed on new domains is the most critical asset. If you have the foundational strength and the drive to lead our next-era AI journey in retail, we encourage you to apply. Core Qualifications
Deep expertise in Generative AI, LLMs, and/or Agentic AI systems (e.g., LLMOps, fine-tuning, RAG, multi-agent orchestration). Strong applied science background with the ability to design, experiment, and deploy cutting-edge ML models in production. Proven experience architecting large-scale ML/AI platforms with attention to performance, scalability, and maintainability. Strong programming and ML tooling skills (Python; PyTorch/TensorFlow). Familiarity with Agentic development platforms (Google ADK, LangGraph, CrewAI, AutoGen). Track record of technical leadership, mentoring, and influencing architectural decisions across teams.
Nice-to-Haves
Experience with broader ML ecosystems: Scikit-learn, Spark ML, XGBoost, or programming languages such as Java, C++, SQL, R. Familiarity with advanced optimization methods (e.g., distributed training, model compression, ONNX interoperability). Exposure to multimodal systems (vision, speech, time series). Strong presence in the AI/ML community (publications, open-source contributions, conference talks). Background in creating inclusive digital experiences and knowledge of accessibility standards (WCAG 2.2 AA) and assistive technologies.
Culture & Benefits At Walmart, we believe AI should be ethical, inclusive, and human-centered.
