  • Architect and deploy autonomous AI agents, including conversational assistants, predictive agents with tool calling, and multi‑agent orchestration systems using LangChain, Pydantic AI, and RAG patterns
  • Design agentic evaluation frameworks to benchmark agent performance across task completion, code quality, and multi‑step reasoning accuracy
  • Deploy NLP pipelines at enterprise scale, enabling semantic similarity across millions of records using BERT/SBERT embeddings and vector search (FAISS)
  • Engineer computer vision systems for real‑time inference (YOLO, RT‑DETR, CLIP) with multi‑GPU training optimization
  • Build time‑series forecasting models that drive inventory optimization, demand planning, and financial projections across multiple geographies
  • Present insights to senior leadership using compelling data visualizations, quantified business impact, and clearly defined confidence intervals
  • Mentor team members on advanced modeling techniques, feature engineering, and experimental design
  • Travel internationally to support Walmart operations in Canada, Chile, Mexico, South Africa, Europe, and the UK
What You’ll Bring
  • Deep expertise in ML algorithms (XGBoost, CatBoost, LightGBM, Random Forest, AutoML) and deep learning (PyTorch, transformer architectures)
  • Production experience with NLP (BERT, SBERT, FAISS, RAG), computer vision (YOLO, CLIP), and time‑series forecasting (ARIMA, Prophet)
  • Hands‑on experience building and orchestrating multiple AI agents with LangChain, RAG, tool integration, and memory management
  • Multi‑cloud ML platform proficiency across AWS SageMaker and GCP (Vertex AI, BigQuery, BigQuery ML)
  • Strong Python skills (Pandas, NumPy, scikit‑learn), containerization expertise (Docker), and MLOps best practices
  • Advanced knowledge of statistical analysis, experimental design, and causal inference
  • Proven ability to translate complex analytical results into clear, actionable business recommendations for non‑technical stakeholders
