About Veriswap

Veriswap is a marketplace for trading cards, operating within the $10B+ sports card secondary market. We’re building a new swap economy because we believe that the trades market is 5x larger than the cash sales market for collectibles. Our mission is simple: empower collectors to trade sports cards anytime, anywhere. Founded in 2021 by alumni from Columbia (ex-Investment Banking) and Brown (ex-Google), Veriswap has quickly become one of the most trusted and active trading platforms for collectors worldwide.

• $120M+ in transactions completed in just three years
• 3x growth in 2024, with transactions as large as $300K

The Role

As a Tech Lead, you’ll take ownership of Veriswap’s backend architecture and be a key voice in how we design, build, and scale our trading platform.
