About us OpenZeppelin is the security standard onchain finance is built on. Founded in 2015, our mission is to accelerate the world's transition to an open financial system, built on open standards and secured by rigorous research. Our open-source Contract Libraries have facilitated over $35 trillion in onchain value and are used by 10 of the top 10 tokenized money market funds and 9 of the top 10 stablecoins by market cap. We combine AI-native security tooling with deep research and a decade of audit expertise to support leading institutions and crypto-native teams shaping the next generation of digital assets like DTCC, Fidelity, Coinbase, Uniswap, Aave, the Ethereum Foundation, and many more across the full secure development lifecycle. Please note: Always refer to OpenZeppelin's official job page for the most accurate information about our open roles, as we have seen multiple third party job sites posting inaccurate information. The Secure Development team ❤️ OpenZeppelin is the security partner of choice for the most important protocols in Web3. Our Secure Development team sits at the intersection of building and breaking: we design, implement, and harden production-grade libraries and smart contracts for leading projects across EVM, Starknet, Stellar/Soroban, Arbitrum Stylus, Aptos, and beyond, often as an embedded extension of the client's engineering team. We work the way the rest of the industry will five years from now. Every developer on the team is a fully AI-native engineer, supported by outstanding internal AI tooling built for every phase of secure development. Developers own their workstreams end-to-end — agents amplify their effectiveness, and peers, security researchers, and external auditors provide rigorous review on every piece of work that ships. The Canton Network engagement This role joins us at the start of a groundbreaking 24-month, multi-million-dollar commitment to build the open-source DeFi foundations of the world's most institutional blockchain. You'll deliver production-ready Reference Implementations (privacy-preserving DEX, lending, cross-chain stablecoin settlement, confidential auction launchpad, and more), the OpenZeppelin Contracts Library for Daml that Canton developers will import, and Canton standards implementation. Within this, you will: • Own the development of the OpenZeppelin Contracts Library for Daml end-to-end: vaults, hooks, RBAC, credentials, messaging gateway, accounts, and more. The audited primitives Canton developers will import. • Lead the technical design and implementation of the year-1 Reference Implementations: privacy-preserving DEX, lending protocol, cross-chain stablecoin settlement, and confidential auction launchpad. • Implement and shepherd the OZ Daml versions of CIP-56, CIP-86, CIP-103, and CIP-104. Coordinate with Digital Asset on spec evolution and with ChainSafe on middleware alignment. • Run client-facing roadmap, design, and milestone discussions with Digital Asset, the Canton Foundation, and ChainSafe. • Collaborate with OpenZeppelin's auditors and security researchers on threat models, audit prep, and full-stack reviews for every Reference Implementation. • Use AI systems as core daily tools. Extend them: build agents, skills, and workflows that compound the team's leverage on the Canton engagement and beyond, including
