💡 Role Description

As a Fall 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

🌍 Visa & Work Authorization

We welcome applicants who are authorized to work in the US, including:

• US citizens and permanent residents

• F-1 students on CPT or OPT

• Canadian citizens (TN visa)

• Irish citizens (J-1 intern visa)

If you're excited about the opportunity to drive innovation at Junior, we'd love to hear from you! We can't wait to meet you! 🙌
