Computational Modeling Simulation Multiphysics Jobs in Arkansas

Position Summary...Job Description Summary
As a Principal Data Scientist and Core Solution Architect, you will be the visionary lead responsible for defining the technical backbone of Walmart's Retail Digital Twin ecosystem. You will move beyond being a "user" of tools to becoming an architect of systems-selecting and integrating best-in-class simulation engines, 3D frameworks, and agentic AI to build a high-fidelity, scalable platform that optimizes the world's largest retail operation.What you'll do...What you'll do:

• Architect End-to-End Systems: Lead the design of a modular, distributed digital twin architecture that balances simulation fidelity with computational efficiency across diverse retail use cases.
• Select & Optimize the Tech Stack: Evaluate and deploy the most effective simulation paradigms (Agent-Based, DES, Physics-based) and tools-whether leveraging AnyLogic, NVIDIA Omniverse, or building custom C++/Python-based engines from the ground up.
• Drive Software Engineering Excellence: Build production-grade, scalable applications that integrate real-time IoT data streams, ensuring the digital twin platform is performant and maintainable at an enterprise scale.
• Lead Agentic AI Strategy: Design the orchestration layer for agentic workflows, enabling intelligent entities within the twin to perform complex reasoning and autonomous optimization.
• Standardize Digital Assets: Define the schema and governance for reusable process blocks (XML/JSON) and 3D CAD assets (USD/gLTF) to ensure interoperability across the organization's pillars.
• Cross-Functional Technical Leadership: Serve as the primary technical liaison between software engineering, data science, and retail operations to align the simulation roadmap with global business objectives.

What you'll bring:

• System Architecture Mastery: 8+ years of experience designing complex, large-scale software systems or simulation environments with a focus on modularity and high-performance computing.
• Tool-Agnostic Expertise: Deep proficiency in a variety of simulation environments and the ability to determine when to use commercial off-the-shelf software (COTS) versus building bespoke solutions.
• Advanced Software Engineering: Expert-level coding skills inC++, Java, or Python, with a strong background in data structures, algorithms, and distributed systems.
• Agentic AI & Optimization: Proven track record of implementing Reinforcement Learning (RL), Multi-Agent Systems (MAS), or Large Action Models (LAMs) within a simulation context.
• Academic Pedigree: PhD or MS in Computer Science, Robotics, Computational Physics, or Industrial Engineering.
