Senior Backend Engineer

Ellipsis Labs is a profitable, venture-backed New York startup building performant DeFi protocols on high-throughput decentralized infrastructure. Our long-term mission is to build a more efficient, transparent, and fair financial system.

Our flagship product, Phoenix Perpetuals, brings professional-grade perpetual futures to Solana. Phoenix has processed over $4 billion in trading volume and is growing 20% month over month, adding to the more than $300 billion our products have facilitated to date.
