Job description:

## About Pure Pure is building the future of rare coin and precious metal trading. We believe collectors and investors deserve better infrastructure for buying, selling, and managing physical assets. Rare coins and precious metals are still traded through outdated systems, opaque pricing, and offline relationships. Pure is changing that by building a modern marketplace focused on transparency, liquidity, and trust. Started in 2023, Pure is one of the fastest growing marketplaces for tangible assets. We currently process over $50 million in transactions each month and are expanding quickly. ## About the Role We are looking for a Product Engineering Intern to join us for Summer 2027. You will work closely with our engineering, product, design, and operations teams to build real features across the Pure marketplace. This is a hands-on internship.

We move fast and care about quality, reliability, and correctness. Ownership matters here. We want interns who are excited to learn, contribute, and ship real software.
