4 days ago Be among the first 25 applicants Job Description About Morpho Morpho is a leading DeFi lending protocol that recently secured $50 million from Ribbit Capital, a16z crypto, Coinbase Ventures, Variant, Brevan Howard, Pantera, Blocktower, and 50 others to build an open lending network giving anyone, anywhere, access to the best possible terms. Morpho is experiencing explosive growth, with over $10 billion in deposits on the network, solidifying itself as the new standard for DeFi lending. Now, Morpho is scaling its team of contributors to establish itself as a cornerstone, not just of DeFi, but of a new internet-native financial system. Our Mission Morpho’s mission is to power human ambition with open access to capital. Human ambition has no borders, but the capital to fuel it does. Today’s financial system is closed and fragmented. No one sees all opportunities, most overpay, and some are excluded entirely. We believe capital should flow efficiently to where it’s needed most — giving anyone, anywhere, access to the best possible terms. Location Paris or remote (from -5 GMT up to +2h GMT to ensure sufficient overlap with the rest of the team).
