Early Careers: Intern, AI Prompt Engineer

Early Careers: Prompt Engineer Intern

The Prompt Engineer Intern will support the design and implementation of AI-powered solutions focused on document intake and intelligent agent development. This role will work closely with AI engineers, software engineers, and product stakeholders to build and refine prompts, retrieval pipelines, and document Q&A/assistant workflows. The intern will spend most of their time working with internal documents (PDFs, emails, reports) to improve how information is ingested, organized, and surfaced through large language models.

Opportunities are availaible in:

Chicago, IL

Bannockburn, IL

Key Responsibilities:

Document Intake & Retrieval (40%)

- Build and maintain document ingestion scripts and pipelines for PDFs, emails, and reports.

- Design and refine metadata schemas and taxonomies to improve document organization and retrieval.

- Clean, normalize, and structure unstructured text to support downstream LLM use cases.

- Contribute to the development and improvement of retrieval-augmented generation (RAG) systems.

- Evaluate retrieval quality (e.g., coverage, recall/precision) and propose improvements.

- Apply security and privacy awareness when handling documents, including PII/redaction workflows.

Agent & Workflow Development (35%)

- Help design and refine LLM-powered agents such as document Q&A assistants, research/summary agents, and workflow assistants that call tools/APIs.

- Configure and iterate system prompts, instructions, and behavior guidelines for agents.

- Implement and maintain simple workflows that connect agents to existing tools and APIs.

- Log, investigate, and analyze agent errors or hallucinations, and suggest prompt or configuration changes.

Prompt Design, Experimentation & Evaluation (20%)

- Design and test prompts for document understanding, summarization, and Q&A use cases.

- Create and maintain evaluation datasets and test cases for prompts and agents.

- Run prompt and agent experiments (including simple A/B tests) and quantify improvements using basic metrics.

- Document findings and best practices for prompt patterns, guardrails, and failure modes.

Collaboration & General Support (5%)

- Work on scoped, independent mini projects with regular mentorship and feedback.

- Collaborate with product owners, scrum masters, and domain experts to clarify requirements and translate them into concrete technical tasks.

- Contribute to light documentation (e.g., experiment notes, runbooks, internal guides) to support knowledge sharing across the team.
