Protocol Engineer (Injective Labs)

About the role

You will architect and deliver core protocol components that power Injective's decentralized finance modules from conception to production. You will own the design, implementation, and rigorous testing of chain features that directly impact performance, reliability, and user experience. Your work will focus on optimizing the Injective blockchain through deep analysis of processing logic, state management, and the order matching engine. You will collaborate with elite engineers to define specifications that balance innovation with stability. You will write open-source Golang clients that expose protocol functionality to external developers and applications. You will play a key role in research initiatives that push the boundaries of blockchain scalability and interoperability. Your contributions will be visible across the Cosmos-SDK ecosystem and beyond.
