• Designs and builds AI agents that execute in workflows within enterprise systems (databases, CRMs, ticketing, knowledge bases) and that are deployed with reliable/safety guardrails
• Implements end-to-end agent orchestration (prompting, memory/state, tool-calling, retries/fallbacks) and develops evaluation frameworks (test suites, simulations, human-in-the-loop review) to improve accuracy and reduce error
• Designs, builds, and maintains Retrieval-Augmented Generation (RAG) GPT applications by integrating enterprise knowledge sources (documents/databases) with embeddings, vector search, and prompt orchestration to deliver accurate, grounded responses with evaluation and safety guardrails
• Analyzes large datasets to uncover trends, patterns, and insights, and creates visualizations and reports to communicate findings to stakeholders
• Monitors and evaluates the performance of data models and systems, and makes necessary adjustments to optimize accuracy and efficiency
• Documents processes, methodologies, and model development to ensure transparency and reproducibility
• Provides training and support to other team members or departments on data tools, techniques, and best practices
• Consults with internal IT teams to ensure infrastructure supports stable, well-designed, highly available, and well-maintained Data Science and AI applications
• Stays current with emerging technologies and industry trends to continuously improve data engineering practices and contributes to the development of cutting-edge solutions
• Ensures the accuracy, consistency, and security of data; implements and enforces data governance policies and best practices.

PHYSICAL REQUIREMENTS:

The work environment characteristics described here are representative of those an employee encounters while performing the essential functions of this job.

Functions involve the periodic performance of moderately physically demanding work, usually involving lifting, carrying, pushing and/or pulling of moderately heavy objects and materials (up to 25 pounds). Tasks that require moving objects of significant weight require the assistance of another person and/or use of proper techniques and

moving equipment. Tasks may involve some climbing, stooping, kneeling, crouching, or crawling. Must be able to safely operate assigned vehicles possibly long distances.
