ABOUT MORPHO Morpho is a leading Decentralized Finance (DeFi) lending protocol that raised $70 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.
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.

HOW WE WORK We move fast on hard problems in a nascent market with no set playbook: navigating uncertainty is part of the job.
You'll be challenged: anyone can question work and decisions must be justified.
