(USA) Senior, Data Scientist - Digital Twin Systems Developer

Job description

Position Summary... As a Senior Data Scientist within the Digital Twin CoE, you will architect a highly modular, high-fidelity digital twin platform that serves as the "operating system" for Walmart’s retail operations. You will be responsible for building the technical bridge between complex process simulations in AnyLogic and immersive, real-time 3D environments, utilizing agentic workflows to drive autonomous, data-driven decision-making. What you'll do... What you’ll do: - Develop Modular Simulation Engines: Lead the development of AnyLogic models using a library-based approach, creating interchangeable process blocks (via XML and Java) that represent discrete retail pillars like "Last Mile," "Backroom Ops," and "Front-End Checkout." - Develop High-Fidelity 3D Pipelines: Create and manage a pipeline for converting and optimizing 3D CAD assets into real-time ready formats (USD, FBX) for deployment in NVIDIA Omniverse, Unreal Engine, or Unity. - Integrate Agentic Workflows: Design and deploy "Agentic" frameworks where simulation entities (associates, customers) are driven by LLM-based reasoning or Reinforcement Learning (RL) rather than static scripts. - Build Reusable Logic Asse...
