• 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
