About Aztec At Aztec, our goal is to add privacy to Ethereum. In the current public blockchain paradigm, users and entities unknowingly broadcast data in the public, compromising privacy and security to get trustlessness. Not only are unencrypted blockchains inherently privacy-exposing, they require significant redundancy to compute and verify the legitimacy of transactions. Implementing scalable encryption in a public blockchain paradigm requires cutting-edge math and engineering. Thankfully, our team of scientists and engineers invented Plonk, the industry-standard zkSNARK, and Noir, the universal language of zero knowledge. Now, we’re building a first of its kind Layer 2 with private smart contracts. This requires new cryptographic primitives, a zero-knowledge DSL for writing contracts, a privacy-friendly execution environment, a carefully designed set of circuits that prove the validity of the chain to L1, a decentralized block-building and proving mechanism, and a top-tier user and developer experience. And it’s now time to bring it to market. We’ve raised $125 million from industry-leading investors including a16z crypto, Paradigm, Variant, Consensys, and a_capital, and we’re growing quickly.Role Overview As a Front-End Software Engineer at Aztec Labs, you’ll be at the forefront of designing and developing intuitive, high-performance user interfaces for developers and users interacting with our zkApps, wallets, and protocol tools. You will collaborate with design, cryptography, and protocol teams to ensure seamless and secure user experiences in a highly technical, fast-paced environment. This is a unique opportunity to help define the UX of privacy in Web3 and shape how users interact with next-gen decentralized systems. Key Responsibilities

Design, implement, and maintain front-end applications for zk-powered tools and dApps. Initial projects in the first months will be designing and developing the frontends for our showcase payment dApp and sequencer staking bootstrap projects, critical for our mainnet launch this year. Work closely with product managers to align UI/UX with product requirements. Work closely with engineers to integrate aztec.js into the apps and provide critical feedback. Create and translate design mockups and wireframes into pixel-perfect, responsive interfaces. Write modular, testable, and maintainable code using modern JavaScript frameworks. Contribute to UI/UX discussions and drive decisions around user experience best practices. Ensure performance, security, and scalability of all front-end applications.

Required Qualifications

3+ years of experience building production-grade front-end applications. Strong proficiency in TypeScript, JavaScript, React or Svelte, and HTML/CSS. A deep understanding of frontend performance optimization, accessibility, and responsive design. A focused, and minimalist approach to engineering and design, avoiding bloat, and keeping the code easy for everyone to maintain. Strong communication and collaboration skills. You will be expected to develop a deep understanding of the requirements, and can then take the initiative to meet them with minimal management. Passion for blockchain technology and a strong desire to build user-first Web3 applications.

Nice to Have

Experience working with Web3 libraries (e.g., ethers.js, viem, wagmi). Familiarity with zero-knowledge proofs, privacy-preserving technologies, or blockchain protocols. Previous contributions to crypto wallets, block explorers, or dApp front-ends. Understanding of UX design principles and familiarity with Figma or design systems. Experience with end-to-end testing frameworks (e.g., Cypress, Playwright). Exposure to Layer 2 solutions and Ethereum development tools.
