Interview Process

We are looking for a senior-level Protocol Engineer to join a core blockchain team building next-generation Web3 payments infrastructure. This role is focused on designing and implementing secure, efficient smart contracts and protocol-level components that power cross-chain value transfer at scale. You will operate at the intersection of smart contract development, DeFi mechanics, and blockchain architecture, contributing directly to systems that enable millions of onchain transactions. The position requires a strong crypto-native mindset, deep Solidity expertise, and the ability to reason about protocol design, security, and cross-chain interactions. You will collaborate closely with backend engineers and product teams to architect payment and settlement infrastructure. This is a high-impact opportunity within a growing blockchain team shaping core Web3 primitives.
