What are the responsibilities and job description for the Predicate - Senior Protocol Lead position at deCircle?
We’re building Predicate, a platform setting the standard for how regulated blockchain applications enforce transaction rules at the smart contract layer. Predicate empowers teams to create modular, programmable policies—such as AML/CFT checks or offchain collateral requirements—that are verified before a transaction executes onchain. Our system enforces these policies with cryptographic guarantees, providing robust, scalable risk management tailored to real-world use cases.
The role
As Protocol Lead, you’ll own the design, development, and maintenance of Predicate’s smart contract suite. You’ll build tooling to support integrations, contribute to core infrastructure, and research emerging technologies to keep us at the forefront of the industry. You’ll also serve as the team’s blockchain subject matter expert, supporting teammates across the stack on all things related to smart contract interactions.
