Senior Frontend Engineer Île-de-France

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. 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 - 5h 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. More about our values: morpho.org/jobs . Role Enable Morpho to deliver world-class DeFi user experiences by building, shipping, and maintaining performant, secure, and intuitive frontend applications that turn complex protocol mechanics into simple, reliable products. Responsibilities Design and ship end-to-end features with React, TypeScript, and Next.js to improve core Prime apps’ usability and adoption. Implement secure Web3 interactions with wagmi and viem to enable seamless wallet connections, transactions, and on-chain data reads. Establish and evolve frontend architectures for scalability by defining patterns for state management, data fetching, and component reuse. Collaborate with Design to translate product specs into accessible, responsive, and pixel-accurate interfaces across devices. Improve performance by analyzing bundle sizes, optimizing loading strategies, and refining Web3 interaction flows for low-latency UX. Raise code quality with thoughtful code reviews, documentation, tests, and continuous refactoring of critical paths. Mentor teammates by sharing React/Web3 best practices and leading knowledge sessions to level up the engineering bar. What Success Looks Like In your first 30 days Set up your environment, ship your first production contribution, and learn the architecture of our Curator V2 and Markets V2 apps. Build relationships with Product, Design, and Protocol teams and participate actively in PRs and planning. Identify 2–3 quick wins for performance, DX, or quality and outline a plan to address them. By Month 4–6 Deliver at least one major feature end-to-end that improves UX or unlocks protocol functionality. Own a core piece of a Prime application and become the go-to person for that area. Build trust by consistently delivering high-quality code and communicating clearly and asynchronously. By Month 12 Lead the architecture and delivery of a new app or major initiative with scalable patterns adopted across teams. Uplevel the Morpho Frontend Guild through mentorship, shared components/tooling, and technical workshops. Establish monitoring and quality systems that reduce production incidents and increase deployment confidence. Adaptability and ownership in a fast-changing, remote-first environment with shifting priorities and time zones. Clear, crisp async communication and proactive context sharing across teams. First-principles thinking with a bias for action. Sees a problem and fixes it, asks for clarification when needed. Team-first mindset with low ego. Optimizes for collective success over individual credit. Crypto curiosity with continuous learning and experimentation, especially in frontend and Web3 tooling. Must-have Experience 4+ years building production-grade React applications. 2+ years with Next.js and TypeScript in modern frontend stacks. Exposure to Web3 tooling (e.g., viem, wagmi) through professional work or serious side projects. Proven track record shipping high-quality web apps, ideally in finance or similarly rigorous domains. Demonstrated capability to improve performance, reliability, and developer experience through testing, reviews, and documentation. We design benefits around deep work and growth, so you can do the best work of your career.
