We are currently seeking a Prompt Engineer to join our team in Jersey City, New Jersey (US-NJ), United States (US).

Prompt Engineer

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.

Basic Qualifications:

  • 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.

Preferred experience

  • 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.
