Vos missions au quotidien
This position is in Zama’s Protocol Apps team
Zama recently unveiled the Zama Confidential Blockchain Protocol, which enables confidential smart contracts on top of any blockchain L1 or L2, using Fully Homomorphic Encryption (FHE). The Protocol Apps team is responsible for building multiple dapps and services that enshrine the protocol, effectively serving as one of its first users.
We are looking for a Frontend Engineer to build intuitive interfaces for our decentralized applications, spanning DeFi, governance, and more. You’ll be the bridge between complex blockchain infrastructure and everyday users—translating smart contract functionality into reliable user experiences.
This role focuses exclusively on frontend development, though you’ll collaborate closely with our smart contract and backend engineers to ensure tight integration across the stack.
What you will do:
Develop and maintain React/TypeScript dapps that interact with EVM smart-contracts using libraries such as ethers.js, viem, or web3.js
Implement wallet connection and Web3 authentication flows (MetaMask, Coinbase Wallet, Privy, etc.)
Work alongside backend developers to integrate off-chain APIs and indexing services (The Graph, Goldsky, custom indexers)
Contribute to UI/UX decisions that simplify complex blockchain interactions for non-technical users
Manage frontend deployments (using platforms like Vercel, Netlify, or similar), CI/CD pipelines, and environment configurations across staging and production
Build for quality from day one: make the app testable in CI and production-safe
Collaborate across dev teams: turn partner/dev feedback into rapid UI iterations
Be strongly product-oriented
Ce que l’on cherche
Bachelor’s degree in Computer Science, Software Engineering, or related field.
3+ years of professional experience in web3 frontend development, with strong React/TypeScript and EVM/Solidity knowledge
Product sense for developer UX: reducing friction, anticipating pain points, and designing intuitive experiences
Experience with wallet integrations and transaction signing flows
Experience deploying frontend applications
Testing discipline: you design testable components and wire contract tests or mocks where they help.
Docs & clarity: You write straightforward docs/quickstarts so any devs can assist you in your tasks seamlessly.
Ownership & collaboration: proactive, great async communication, and comfort working with smart-contract/backend engineers.
Nice to have
Experience with DeFi and DAO interfaces
Contributions to open-source Web3 projects
Understanding of backend concepts (REST APIs, WebSockets, databases)
Familiarity with indexing solutions like The Graph, Goldsky or custom subgraphs
