Blockchain Engineer

About the Role

As a Blockchain Engineer at Ondo, you will help design our smart contract systems - not just the contracts themselves, but how they re deployed, secured, monitored, and managed across their entire lifetime, and how they connect to the people and products that depend on them. You ll design secure, efficient, and scalable smart contract solutions across many blockchain ecosystems powering Real World Asset (RWA) tokenization. But the harder and more important part of this role is everything around the contract: keeping it secure from deploy through every day it s live, building tooling that lets non-technical teammates safely view and manage on-chain state, and creating automated systems that take manual, error-prone work off the table. You ll think about how a smart contract design decision ripples outward, to the web app, to the teams operating the system day to day, and ultimately to our end users. You ll collaborate with product, legal, compliance, web, and ops to make sure contracts are technically sound, regulatorily aligned, and genuinely operable by the teams who rely on them day to day. Throughout, you ll favor simple, elegant designs that let us move quickly and safely. This is a unique opportunity to shape the future of finance by building the systems that bring real-world assets on-chain, and by making those systems something a whole organization can build on with confidence.
