OpenZeppelin is a privately held blockchain cybersecurity company founded in 2015, operating as a fully distributed, remote-first organization with team members spread across six continents, including North America, South America, Europe, and beyond, with no single fixed headquarters -- though it has been variously registered in locations including the Cayman Islands and San Francisco. The company builds and maintains open-source smart contract libraries, conducts professional security audits, and offers the Defender developer security platform, which integrates into clients' development lifecycles to help teams plan, code, audit, deploy, and operate decentralized applications more safely. OpenZeppelin serves over a thousand blockchain protocols and organizations, including well-known names across the DeFi, institutional, and infrastructure segments of the Web3 ecosystem, and its open-source contract libraries have reportedly facilitated the transfer of over $35 trillion in on-chain value. Employee count varies significantly across sources -- estimates range from approximately 58 to 175 people -- reflecting its lean, distributed structure. The company's workforce is organized across several key functions, with Security Research carrying the highest volume of specialized open roles, followed by Engineering (covering smart contract development, backend infrastructure, and zero-knowledge systems). Other active departments include Growth & Revenue, Sales, Marketing, Project Management, People Operations, and Partnerships & Solutions Architecture. All roles at OpenZeppelin are fully remote. This page lists the latest job openings at OpenZeppelin, offering professionals an opportunity to contribute to the security and resilience of the decentralized web.
