I am currently partnered with a highly regarded blockchain protocol team who are evolving a live, production-grade network and undertaking a major architectural transition from a Cosmos SDK–based design to a fully smart contract–driven protocol on the EVM. Working closely with a senior, globally distributed engineering team, you will play a pivotal role in redesigning the core protocol logic to operate fully on-chain. This includes replacing existing Cosmos modules with modular, upgradeable Solidity contracts while ensuring best-in-class security, scalability, and long-term economic sustainability. This is an outstanding opportunity for a Staff-level Smart Contract Engineer to have direct influence over the technical direction of a live protocol, contributing to critical architectural decisions and shaping the future evolution of the network.
Job Responsibility:
Act as a core contributor in the design and development of modular, upgradeable Solidity smart contracts deployed on EVM-based chains
Translate existing protocol logic from a Cosmos SDK–based architecture into efficient, secure, EVM-native implementations
Collaborate closely with core engineering, DevOps, and product teams on protocol architecture, tokenomics, and on-chain/off-chain integrations
Drive best practices around security, upgradability, and scalability across the smart contract stack
Requirements:
Strong hands-on experience designing and deploying production-grade Solidity smart contracts on EVM chains
Deep understanding of EVM internals, security considerations, and upgradeability patterns
Experience contributing at a senior or staff level within a blockchain or protocol-focused engineering team
Prior exposure to Cosmos SDK or similar modular blockchain frameworks is highly desirable
Genuine passion for decentralised systems and building resilient, long-term blockchain infrastructure
