About the role

As an Applied AI Engineer Intern, you'll be embedded directly with our Engineering team, working hands-on on one of our most ambitious initiatives: an AI-first product built from the ground up. This isn't a "run reports and sit in meetings" internship; you'll be writing real code, experimenting with cutting-edge AI/ML models, and solving hard problems that directly impact how lenders and borrowers experience our platform.

You'll collaborate closely with engineering and product members to design and ship AI-driven features, optimize model performance, and help establish the technical foundation for a product that's redefining what a modern SaaS lending platform can do. If you're excited about applying large language models, building intelligent pipelines, and seeing your work go to production, this is the internship for you.

What you'll do

• Build AI powered workflows using LLMs.
• Develop agentic in-app experience that enables users to interrogate, explore, and act on data insights.
• Develop strategies to test and optimize prompts.
• Work on OCR, Document Classification, Extraction, and Summarization systems.
• Build Retrieval Augmented Generation (RAG) pipelines.

Qualifications

• Strong programming skills in Python and/or Typescript.
• Basic understanding of agent frameworks (e.g., LangGraph) and retrieval-augmented generation (RAG).
• Interest in prompt engineering, optimization, and evaluation methods for improving real-world model performance.

Why Join Us?

• Collaborative, supportive team known for long tenure, deep expertise, and a culture built on trust and integrity.
• Help modernize and evolve the leading platform in private lending technology.
