The role ensures model outputs are accurate, grounded, safe, consistent, cost-aware, and aligned with business and compliance expectations.

• Prompt testing, versioning, evaluation, and quality-improvement workflows.


• Reusable prompt libraries and guardrail patterns for business teams and responsible citizen development where applicable.

• Design prompts for chatbots, copilots, RAG systems, document analysis, summarization, workflow agents, knowledge assistants, and decision-support experiences.


• Develop system prompts, few-shot examples, tool-use instructions, response formats, escalation logic, citation behavior, and conversation policies.


• Optimize prompts for KYC support, credit underwriting support, governance tracking, pitch book generation, Banker 360, Customer 360, deal library intelligence, financial crime quality, and sanctions screening use cases.


• Build reusable prompt libraries and templates aligned to enterprise standards, business domains, AIRP patterns, and citizen-development guardrails.


• Evaluate prompt performance using metrics such as task success, groundedness, hallucination rate, completeness, safety, user satisfaction, latency, and token cost.


• Partner with engineers to implement prompt versioning, testing, deployment, and monitoring in production systems and CI/CD workflows.


• Support RAG quality by assessing retrieval context, chunking quality, source citation behavior, response synthesis, and missing-context behavior.


• Conduct adversarial testing for prompt injection, jailbreaks, instruction conflicts, sensitive-data leakage, unsafe outputs, and unauthorized tool use.

• 3+ years of experience with LLM behavior, prompt design, tokenization, context windows, RAG, embeddings, and model limitations.


• 3+ years of experience experience with OpenAI APIs, Azure OpenAI, AWS Bedrock, Anthropic, LangChain, LlamaIndex, Semantic Kernel, Copilot Studio, or similar platforms.


• 3+ years of experience debugging LLM outputs using structured testing, error analysis, and iterative refinement.


• 3+ years of experience with prompt-security risks including prompt injection, jailbreaks, data leakage, hallucination, and instruction conflicts.


• 3+ years of experience creating repeatable prompt templates and evaluation evidence suitable for enterprise governance.

• Strong writing, analytical, communication, and stakeholder-management skills.


• Background in NLP, conversational AI, UX writing, technical writing, product design, knowledge management, business analysis, or financial-services operations.


• Experience in financial services, legal, compliance, risk, operations, customer support, banker productivity, or enterprise knowledge domains.


• Familiarity with Microsoft Copilot Studio, Power Platform, prompt registries, A/B testing, human review workflows, and evaluation tooling.
