AI / ML Engineer (Unpaid for OPT Credit)

ReferU.AI is hiring an AI / ML Engineer to build and improve Link, its production consumer intake and attorney-matching product. The role focuses on LLM-powered conversational intake, attorney matching, retrieval, agent workflows, data pipelines, and evaluation, while collaborating with product, design, and legal experts.

Responsibilities:

• Build and improve the AI that powers Link, our consumer intake and attorney matching product in production at referu.ai, from conversational intake through matching consumers with attorneys who have handled similar cases
• Improve the matching and ranking logic that connects people with attorneys who have handled similar cases
• Design and improve RAG pipelines: chunking, retrieval, ranking, and context assembly
• Build and orchestrate agents and tool-calling workflows, with guardrails that keep conversations safe and on task
• Move quickly from experiments and prototypes to reliable, maintainable production services on Cloud Run
• Own testing, monitoring, and deployment for the systems you build, and help raise the team’s engineering standards
• Build ingestion and processing for the data behind intake and attorney matching, including case records, intake conversations, and other unstructured documents
• Design schemas, embeddings, and features that make retrieval and reasoning more accurate and robust
• Design and run evaluations that measure model quality, retrieval performance, and user-facing outcomes
• Build evaluation suites and dashboards that track quality over time (e.g., accuracy, groundedness, hallucination rate), and use product analytics to connect model changes to user outcomes
• Work with product, design, and legal experts to understand user needs and turn them into concrete technical plans
• Participate in sprint planning, code reviews, and technical discussions as part of a small, high-ownership team
