Recruiter red flags
Only casual ChatGPT usage; no structured evaluation; no understanding of RAG or prompt security; no prompt versioning; unable to quantify improvement or work within regulated business controls.
Role purpose
Design, test, govern, and continuously improve prompts, system instructions, conversation flows, and interaction patterns for AIRP LLM applications and related citizen-development experiences. The role ensures model outputs are accurate, grounded, safe, consistent, cost-aware, and aligned with business and compliance expectations.
Client-specific emphasis
Prompt work must support enterprise business use cases, not generic chatbot experimentation.
Reusable prompt patterns should be suitable for AIRP and, where applicable, Copilot Studio / Power Platform citizen-development scenarios.
Candidates must understand prompt security, sensitive data handling, citations/grounding, and structured evaluation.
Primary ownership
Prompt patterns, system instructions, response templates, and conversation policies for AIRP LLM use cases.
Prompt testing, versioning, evaluation, and quality-improvement workflows.
Reusable prompt libraries and guardrail patterns for business teams and responsible citizen development where applicable.
Key responsibilities
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.
Must-have candidate profile
Strong understanding of LLM behavior, prompt design, tokenization, context windows, RAG, embeddings, and model limitations.
Hands-on experience with OpenAI APIs, Azure OpenAI, AWS Bedrock, Anthropic, LangChain, LlamaIndex, Semantic Kernel, Copilot Studio, or similar platforms.
Ability to debug LLM outputs using structured testing, error analysis, and iterative refinement.
Strong writing, analytical, communication, and stakeholder-management skills.
Understanding of prompt-security risks including prompt injection, jailbreaks, data leakage, hallucination, and instruction conflicts.
Ability to create repeatable prompt templates and evaluation evidence suitable for enterprise governance.
Preferred experience
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.
Initial screening questions
Show how you improved a weak LLM output through prompt design and testing.
How do you evaluate prompt performance beyond subjective quality?
How would you create reusable prompt templates for KYC, pitch book generation, Customer 360, or sanctions screening?
How do you prevent prompt injection, data leakage, or instruction conflicts?
How do you work with engineers to move prompts into production safely?
How would you govern prompts used by citizen developers in Copilot Studio or Power Platform?
