About the Company

Gemini is a global crypto and Web3 platform founded by Cameron and Tyler Winklevoss in 2014, offering a wide range of simple, reliable, and secure crypto products and services to individuals and institutions in over 70 countries. Our mission is to unlock the next era of financial, creative, and personal freedom by providing trusted access to the decentralized future.

The Department : Onchain

Our team’s mission is to enable Gemini’s internal and external users to seamlessly interact with blockchain networks in a stable, secure, straightforward way. The Onchain group builds Gemini’s onramps to the blockchain “from CSS to ECDSA.” Our teams are solving problems across the entire crypto product user journey, including the user experience of crypto transfers, custody and staking down to the lowest levels of blockchain protocols and cryptographic signing algorithms. Our systems facilitate on-chain transactions for billions of USD worth of digital assets using state-of-the-art technology and security. We have openings across many of our teams, including Asset Transfers, Staking, Cloud Wallets, Protocols, Signing, and Blockchain Infrastructure. The teams are small, capable, agile, and have extensive ownership of the systems and solutions. We are continually growing, solving unique problems, and discovering new opportunities.
