I'm looking for a senior smart contract developer with at least 3 years of professional experience building production blockchain applications. You should have strong experience with both Solidity and Rust and be comfortable developing secure, efficient, and maintainable smart contracts. Experience with DeFi protocols, token standards, staking, wallets, or other blockchain infrastructure is a plus.
