💡 Role Description
As a Summer Engineering Intern, you’ll be embedded directly in our engineering team and own a meaningful project end-to-end. You’ll ship real code, collaborate with full-time engineers, and present your work to the team at the end of the summer. This is not a passive learning experience — we expect you to contribute from day one.
🔧 What You’ll Work On
Building AI-powered features using LLMs to process and structure unstructured research data
Contributing to our Next.js / TypeScript frontend for client-facing products
Working on data pipelines that turn raw investment research into structured knowledge
🔥 What We’re Looking For
Currently pursuing a degree in Computer Science, Software Engineering, or a related field
Comfortable working in TypeScript / JavaScript — Next.js experience is a plus
Curious about AI and LLM-powered products
Strong communicator who can work closely with a small, fast-moving team
Previous internship or co-op experience is a bonus, not a requirement
🌵 What You’ll Get
$40/hr compensation
Free daily breakfast/lunch — we have an in-office cook
MacBook for the duration of the internship
Dedicated engineering mentor
Real ownership — your code ships to production
Final project presentation to the full team
Consideration for a return offer based on performance
