Career Renew is recruiting for one of its clients a Senior DevOps Engineer - Blockchain - candidates need to be based in the US, there is a preference for NY.

We're building a decentralized protocol that fundamentally transforms how smart contracts handle transaction prerequisites. Our protocol enables developers to compose modular rules (from AML checks to offchain collateral requirements) that are verified before transactions hit the chain, and enforced by a network of operators in a trust-minimized and verifiable fashion.

The protocol introduces a novel primitive that compose into onchain policies. These policies, owned and governed by application developers or DAOs, define the prerequisites for transaction execution. Our operator network ensures that these rules are enforced with cryptographic guarantees, enabling sophisticated transaction validation without compromising on decentralization.
