Data Scientist Jobs

About The Position

Requirements

• 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 — AWS SageMaker AND GCP (Vertex AI, BigQuery, BigQuery ML).
• Strong Python skills (Pandas, NumPy, Scikit-learn) with containerization (Docker) and MLOps practices.
• Advanced statistical analysis, experiment design, and causal inference
• Experience deploying production-grade AI systems at scale.
• Ability to translate complex analytical results into clear business recommendations for non-technical stakeholders.
• Masters degree in Statistics, Economics, Mathematics, Computer Science, Information Technology, or related field AND 8+ years’ experience in data science or Machine Learning roles with demonstrated impact.

Nice To Haves

• PhD in AI, Machine Learning, Computer Science, Information Technology, Statistics, Applied Mathematics, Econometrics, or related field with relevant industry experience.
• Data science, machine learning, optimization models
• Publications or active peer reviewer in related journals or conference
• Successful completion of one or more assessments in Python, Spark, Scala, or R
• Using open source frameworks (for example, scikit learn, tensorflow, torch)
• Knowledge in implementing Web Content Accessibility Guidelines (WCAG) 2.2 AA standards, assistive technologies, and integrating digital accessibility seamlessly.
• Knowledge of accessibility best practices and join us as we continue to create accessible products and services following Walmart’s accessibility standards and guidelines for supporting an inclusive culture.

Responsibilities

• Build and deploy production ML systems end-to-end: data pipelines, feature stores, model training, serving layers, monitoring, and feedback loops at scale
• Provide technical vision and lead advanced development in agentic AI, reinforcement learning, and simulation.
• Architect and deploy large-scale AI systems and autonomous AI agents — conversational assistants, predictive agents with tool-calling, and multi-agent orchestration systems using LangChain, Pydantic AI, and RAG patterns
• Design agentic evaluation frameworks that benchmark agent performance across task completion, code quality, and multi-step reasoning accuracy
• Deploy NLP pipelines at enterprise scale — semantic similarity across millions of records using BERT/SBERT embeddings and vector search (FAISS)
• Lead high-impact projects end-to-end; problem framing, modeling, prototyping, production architecture, and rollout.
• Author and review technical designs and standards; present findings to senior leadership.
• Mentor senior scientists and engineers on advanced modeling techniques, feature engineering, and experimentation design - raising the technical bar across teams.
• Establish best practices for model validations, experiemention, and safe deployment of AI systems.
• Influence roadmap prioritization and long-term strategy for AI and simulation capabilities.
• Present insights to senior leadership with compelling data visualization, quantified business impact, and clear confidence intervals.
