This role is strongly oriented toward **applied Generative AI** , with a primary focus on designing, experimenting with, and evaluating **LLM-enabled systems** that operate on large volumes of unstructured customer interaction data. The consultant will own the end-to-end experimentation lifecycle for **GenAI use cases** - including prompt and agent design, iterative testing, error analysis, tuning, and evaluation - while leveraging traditional machine learning and NLP techniques where appropriate to support or augment GenAI solutions. The role emphasizes practical execution, rapid prototyping, and disciplined evaluation to ensure outputs are reliable, explainable, and suitable for use in risk-aware, human-in-the-loop decision environments. In this role, you will + Lead hands-on **Generative AI experimentation** , including prompt engineering, prompt library development, and agent-style workflows that support voice-of-customer understanding, issue identification, and decision support. + Design and execute **systematic testing of LLM outputs** across large collections of historical customer interaction data, evaluating behavior across tasks, data conditions, and edge cases. + Conduct **deep error analysis of GenAI outputs** , identifying hallucinations, weak or missing evidence, false positives, false negatives, and ambiguity, and translate findings into targeted prompt and system improvements. + Develop and apply **GenAI evaluation frameworks** , including rule-based heuristics, statistical indicators, and LLM-as-a-Judge techniques, to assess output quality, consistency, and risk. Build and refine **confidence and uncertainty scoring mechanisms** for LLM decisions to support prioritization and secondary human review in higher-risk scenarios. + Apply machine learning and **NLP models** where appropriate to complement GenAI solutions, such as feature extraction, classification, clustering, or signal generation. + Analyze complex structured and unstructured datasets to generate hypotheses, surface emerging risks, and identify opportunities where GenAI can augment or automate decision workflows. + Collaborate closely with product teams, engineers, and business stakeholders to align GenAI experimentation with operational workflows, risk tolerance, and real-world constraints. + Produce clear documentation of prompts, experiments, evaluation methods, and findings to ensure transparency, repeatability, and knowledge sharing.Communicate GenAI behaviors, trade-offs, limitations, and risks effectively to non-technical stakeholders, helping set appropriate expectations for usage. + May mentor teammates by sharing best practices related to GenAI experimentation, evaluation, and responsible deployment., Employees support our focus on building strong customer relationships balanced with a strong risk mitigating and compliance-driven culture which firmly establishes those disciplines as critical to the success of our customers and company. They are accountable for execution of all applicable risk programs (Credit, Market, Financial Crimes, Operational, Regulatory Compliance), which includes effectively following and adhering to applicable Wells Fargo policies and procedures, appropriately fulfilling risk and compliance obligations, timely and effective escalation and remediation of issues, and making sound risk decisions. There is emphasis on proactive monitoring, governance, risk identification and escalation, as well as making sound risk decisions commensurate with the business unit's risk appetite and all risk and compliance program requirements. ## Related Videos - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [Pioneering AI Assistants in Banking](https://www.wearedevelopers.com/videos/1627-pioneering-ai-assistants-in-banking) - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [The Innovation Formula: Fast Prototyping, Data Analysis, and Real User Insights](https://www.wearedevelopers.com/videos/1421-the-innovation-formula-fast-prototyping-data-analysis-and-real-user-insights) - [Data Science on Software Data](https://www.wearedevelopers.com/videos/162-data-science-on-software-data) - [Beyond GPT: Building Unified GenAI Platforms for the Enterprise of Tomorrow](https://www.wearedevelopers.com/videos/1525-beyond-gpt-building-unified-genai-platforms-for-the-enterprise-of-tomorrow) ## Related Articles - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Got AI ideas but no money?
