Data Scientist enhancing merchandising and inventory performance using machine learning techniques at Nordstrom. Collaborating with teams to develop data - driven solutions for better customer experiences.
About the role
- Senior Data Scientist developing advanced ML and Generative AI applications at Emerson. Leading projects in AI solutioning, deployment, and cloud-based environments.
Responsibilities
- Design, develop, and deploy advanced ML, DL and Generative AI models (LLMs, Transformers, Diffusion, GANs, VAEs) for NLP, multimodal, forecasting, recommendation, and intelligent automation use cases.
- Lead data-driven GenAI solutioning, including problem framing, feature engineering, dataset curation and statistical validation for enterprise AI applications.
- Perform exploratory data analysis (EDA), bias detection, data quality checks, and advanced feature engineering on structured and unstructured data (text, image, tabular).
- Monitor and manage data drift, model drift, hallucination risks and performance degradation, and define retraining and recalibration strategies.
- Engineer end-to-end RAG pipelines and multi-agent workflows using LangChain, Copilot, MCP.
- Build and optimize RAG pipelines, semantic search, and contextual reasoning workflows using embeddings, chunking strategies, hybrid retrieval, and reranking techniques.
- Integrate vector DBs (PostreSQL, Pinecone, Weaviate, Chroma, FAISS, Redis) and graph DBs (Neo4j, Postgres/pgvector) for semantic retrieval and contextual reasoning.
- Optimize foundation models (GPT, LLaMA, Mistral, Falcon) via prompt engineering, RLHF, LoRA, quantization, and hyperparameter tuning.
- Build scalable AI solutions using Azure AI/ML (preferred) with containerized deployments (Docker, Kubernetes).
- Apply MLOps, LLMOps best practices: CI/CD, model versioning, drift detection, observability, and lifecycle management with MLflow, Kubeflow, Airflow, and monitoring tools.
- Develop secure AI pipelines and APIs with Python, FastAPI/Flask, RBAC, OAuth2, JWT, and encryption standards.
- Conduct model optimization: prompt engineering, hyperparameter tuning, cross-validation, and performance monitoring.
- Use tools like Azure Machine Learning, OpenAI API, HuggingFace, or custom PyTorch/TensorFlow-based models.
- Implement AI safety, bias mitigation, interpretability (SHAP, LIME, and compliance guardrails (GDPR, HIPAA, ISO).
- Collaborate with cross-functional teams to deliver enterprise-grade copilots, assistants, and reusable AI components.
- Document AI design, model workflows, and deployment pipelines for audit readiness and knowledge sharing.
Requirements
