<strong>About Aztec<br><br></strong>At Aztec, our goal is to add privacy to Ethereum.<br><br>In the current public blockchain paradigm, users and entities unknowingly broadcast data in the public, compromising privacy and security to get trustlessness.<br><br>Not only are unencrypted blockchains inherently privacy-exposing, they require significant redundancy to compute and verify the legitimacy of transactions.<br><br>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.<br><br>Now, weâre 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 itâs now time to bring it to market.<br><br>Weâve raised $125 million from industry-leading investors including a16z crypto, Paradigm, Variant, Consensys, and a_capital, and weâre growing quickly.<br><br><strong>What Youâll Do<br><br></strong>Weâre looking for entrepreneurial, impact-driven engineers who thrive in fast-paced environments and want to be at the forefront of privacy-first decentralized applications. Youâll be part of a highly collaborative team working on the client-side stack that powers Aztec's zero-knowledge execution environment.<br><br><strong>You Will<br><br></strong><ul><li>Design and build tools & SDKs that enable developers to build powerful, privacy-preserving dApps on Aztec.</li><li>Develop a secure client-side execution environment, used by wallets and applications to produce and handle encrypted transactions.</li><li>Architect reusable patterns and libraries for writing auditable and verifiable Aztec smart contracts.</li><li>Collaborate cross-functionally with protocol, cryptography, and product teams to build end-to-end privacy-preserving applications.</li><li>Refactor, document, and test existing code for maintainability, performance, and correctness.</li><li>Identify and reduce technical debt, while continuously improving architecture and developer ergonomics.<br><br></li></ul><strong>What Weâre Looking For<br><br></strong><ul><li>3+ years of professional software engineering experience, ideally in blockchain or cryptography-related systems.</li><li>Deep proficiency in TypeScript, with strong software architecture and API design skills.</li><li>Working knowledge of system-level concerns such as performance tuning, memory management, and secure data handling.</li><li>Able to provide thoughtful code reviews and mentor other engineers.</li><li>Comfortable working autonomously and asynchronously within a distributed team.</li><li>Located in or able to work within GMT to EST time zones.<br><br></li></ul><strong>Bonus Points<br><br></strong><ul><li>Experience with Rust, Solidity, or other smart contract languages.</li><li>Contributions to open source projects, especially in the Web3 or cryptography space.</li><li>Familiarity with zk systems like ZCash or other privacy-preserving protocols.</li><li>Exposure to modern web development frameworks and tooling.</li><li>Passion for zero-knowledge cryptography and its role in reshaping the internet.<br><br></li></ul><strong>What We Offer<br><br></strong><ul><li>Flexible, remote-first culture with HQ in London.</li><li>Competitive salary + equity/token options.</li><li>25 days annual leave + bank holidays.</li><li>Health, dental, and retirement benefits (based on location).</li><li>Quarterly offsites for team collaboration and bonding.</li><li>Conference and learning budget for continual professional development.</li><li>A chance to work on truly cutting-edge zero-knowledge infrastructure with some of the best minds in the field.<br><br></li></ul>Aztec Labs is an equal opportunity employer and we value creativity, diversity, and intellectual curiosity.
