Staff/Senior Backend Engineer

About Morpho Morpho is a leading Decentralized Finance (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.

Job Description We are looking for a backend engineer to build and maintain reliable, high-performance backend services and APIs that power Morpho’s consumer and business-critical features. Depending on experience level, this role may include ownership of entire backend domains, mentoring other engineers, and driving cross-team impact.

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).

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. We keep a high bar and match it with high support: we help each other unblock and share context openly, with low ego.
