You are comfortable with the unknown and understand that #startuplife means that you will be wearing multiple hats. Responsibilities Extend the scope and depth of our automated program verification tools and brainstorm, design, and implement new tools. Adapt and improve algorithms for symbolic software model checking. Examples include bounded model checking (BMC), counterexample-guided abstraction refinement (CEGAR), and property directed reachability (IC3/PDR). Build and extend translators from different input languages into intermediate representations, optimizing the generated models for automated analysis. Identify new classes of security properties of smart contracts and formalize properties for use in our automated verification tools. Closely collaborate with other software engineers in developing tools and set technical direction for solving problems in consultation with your team and management.

Location: Remote Workplace: Remote We are building AI to simulate the world through merging art and science. We believe that world models are at the frontier of progress in artificial intelligence. Language models alone won’t solve the world’s hardest problems – robotics, disease, scientific discovery. Real progress requires models that experience the world and learn from their mistakes, the same way that humans do. And this kind of trial and error can be massively accelerated when done in simulation, rather than in the real world. World models offer the most clear path to general-purpose simulation, changing how stories are told, how scientific progress is made and how the next frontiers of humanity are reached. Our team consists of creative, open minded, caring and ambitious people who are determined to change the world. We aspire to continuously build impossible things and our ability to do so relies on building an incredible team. If you are driven to do the same, we'd love to hear from you. *Titles posted to our careers page are updated regularly to best advertise the role and expected seniority, but internally we have a flat titling system with two types of titles: one for individual contributors and one for people managers.

Location: Remote - Worldwide 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 Security Services Team OpenZeppelin's Security Services team is responsible for the security of the world's leading web3 protocols and top financial institutions building onchain. Our researchers partner with client teams across the full lifecycle of a protocol: working on architecture and design before any code is written, co-creating novel mechanisms and primitives with engineering teams, conducting deep audits of pre-launch codebases, and providing continuous coverage as production systems evolve. Our clients range from emerging projects shipping their first contracts to global financial institutions running production onchain systems at scale. What you'll be doing Review smart contracts for top decentralized applications, blockchain infrastructure and financial institutions before they launch. Find vulnerabilities, prioritize them, and present findings to the client. Drive audits independently from start to finish, with AI as your primary collaborator. When useful, partner with another researcher to attack the code together and pressure-test findings. Partner with client teams during the design phase of new protocols, analyzing architecture, trust assumptions, and operational constraints before any code is written (Design Reviews, Applied Research engagements). Use AI efficiently throughout the audit process, and build skills, agents, and workflows that compound across the team. Conduct open-ended research into cutting-edge blockchain technologies, vulnerability classes, and emerging attack vectors, and contribute findings back to OpenZeppelin's internal knowledge base and to the broader ecosystem. You have Hands-on and practical experience in one or more of the following: software development, cybersecurity, applied mathematics, distributed systems, cryptography, cryptoeconomics or game theory, or DeFi mechanisms. Experience designing and developing smart contracts, not only auditing them. Strong working knowledge of Solidity and the broader Ethereum / EVM ecosystem (common libraries, frameworks, smart contract patterns). Modern AI tooling is central to how you work, not a novelty. You use it daily to expand audit coverage, reason about complex systems, and produce high-quality outputs faster. You evaluate AI-generated code with a critical eye. Comfort building and extending your own tooling (skills, agents, prompts, scripts, or full workflows) that the rest of the team can adopt and build on. An advanced English level and strong communication skills (oral and written). Nice to have Experience with non-EVM ecosystems and languages, such as Canton, Move (Sui, Aptos), Golang (Cosmos SDK), Cairo (Starknet), Rust-based blockchains (Solana, Stellar), or ZK circuits and cryptography-heavy systems. Experience with risk assessment work in the crypto industry (smart contract risk assessment, threat modeling). Working hand-in-hand with protocol teams on co-creative engagements, helping design, specify, and implement smart contracts alongside the research. Web2 security expertise (penetration testing, web application security, infrastructure security, or appsec). Experience with formal verification, invariant testing, or advanced fuzzing tools (Echidna, Foundry, Halmos, Certora). A track record in audit contests (Code4rena, Sherlock, Cantina) or bug bounty platforms (Immunefi, HackerOne). Public security research output, such as published findings, blog posts, conference talks, or contributions to open-source security tooling.
