About the role
We are looking for a Senior Fullstack Engineer with 3-5+ years of experience to build the financial engine powering Alt's double-sided marketplace for trading cards. You'll own real-time payments infrastructure processing large ACH transactions across a platform that grew 505% last year — this is not credit card processing, this is moving serious money.
What will you be doing?
- Processing thousands of large-value transactions ($100K+) through Stripe and banking partner integrations
- Building and maintaining a custom double-entry ledger system for the marketplace
- Developing new ledgers for future lending and financial products
- Working 70% backend (Python) with React/React Native on the frontend
- Collaborating on a small payments pod (3 engineers total) operating on a ticketing basis
About Alt
Alt is unlocking the value of alternative assets, starting with the $5B trading-card market. We let collectors buy, sell, vault, and finance their cards in one place and we are backed by leaders at Stripe, Coinbase, Seven Seven Six, and pro athletes like Tom Brady and Giannis Antetokounmpo. Our next frontier is real-time pricing at scale—the Alt Value that powers every trade, loan, and product on the platform.
