Smart Contract Engineer (Protocol / DeFi)Compensation: $180,000–$250,000 base salary competitive equityLocation: NYC preferred; open to U.S. / Canada / MexicoWork Model: In-person strongly preferred; hybridOverviewA fast-growing on-chain financial infrastructure company is building mission-critical DeFi protocols for enterprise adoption and is seeking hands-on Smart Contract Engineers to join its core protocol team.The team has shipped multiple decentralized primitives across lending markets, vaults, and other financial protocols. This role is for engineers who can research, design, and implement production-grade Solidity systems, not just write contracts in isolation.The RoleYou will work on the design and implementation of novel DeFi protocols, with a strong emphasis on lending, vaults, and capital efficiency. This is a deeply technical role with real ownership over protocol architecture, trade-off analysis, and security posture.The ideal candidate is fluent in DeFi mechanics, understands real-world protocol constraints, and has shipped main net Solidity code used by real users.Key ResponsibilitiesResearch and design new protocol mechanisms around vaults, lending markets, and other DeFi primitivesLead protocol design decisions, balancing trust assumptions, capital efficiency, and securityImplement Solidity smart contracts and develop comprehensive test suitesMaintain high standards for code quality, documentation, and security in an open-source environmentWhat Were Looking ForCore InterestsCandidates should demonstrate strong interest and experience in one or more of the following:DeFi yield strategiesTokenizationDecentralized lendingUnder-collateralized and uncollateralized lending systemsRequired Experience & SkillsProven track record shipping production Solidity protocols on main net (not limited to hackathons or demos)Deep familiarity with lending and vault architectures (e.g., Compound-style, vault-based, or credit protocols)Solid understanding of AMMs, RFQs, aggregators, and cross-chain architecturesBonus QualificationsParticipation in CTFs, gas optimization (gas golfing), or competitive hackathonsExperience beyond Solidity, including rollups or blockchain infrastructureActive DeFi user, investor, or protocol participantKnowledge of node operations, rollup design, or zero-knowledge systemsCompensation & LogisticsBase Salary: $180,000–$250,000 (based on experience and scope)Equity: Competitive equity package includedLocation: NYC preferred (in-person strongly favored);
