Senior DeFi Engineer

This is a fully remote position, open to applicants in Switzerland.

📋 Description

• Design and implement smart contracts and DeFi protocols that form the foundation of Nexus Mutual's risk, capital, staking, and coverage framework.

• Develop and enhance methods for capital allocation, liquidity, staking, pricing, incentives, and risk management.

• Transform intricate financial mechanisms into reliable on-chain systems in collaboration with protocol, product, and research teams.

• Analyze DeFi protocols and primitives for potential integration, optimization, or innovative protocol design opportunities.

• Create integrations with DEXs, lending protocols, liquidity venues, oracles, and other on-chain infrastructures.

• Establish systems for deploying and overseeing capital across various risk and return profiles.

• Contribute to the architecture, economic design, and technical specifications of the protocol.

• Develop secure, gas-efficient, and composable Solidity contracts.

• Create testing, simulations, monitoring tools, and resources related to protocol behavior.

• Engage in security reviews and pinpoint economic, smart contract, and integration risks prior to deployment.

• Examine protocol behavior through on-chain data, simulations, and quantitative analysis.

• Assess protocol upgrades and new DeFi primitives alongside engineers and researchers.

• Contribute to technical documentation, research, and open-source development within the Nexus Mutual ecosystem.

⛳️ Requirements

• A minimum of 5 years of software engineering experience, particularly in building production DeFi or blockchain systems.

• Strong proficiency in Solidity and the EVM.

• Comprehensive understanding of DeFi primitives, including AMMs and DEXs, lending and borrowing, staking and restaking, liquidity provision, yield strategies, oracles, token economics, on-chain governance, and capital allocation mechanisms.

• Experience in designing and deploying production smart contracts that manage significant economic value.

• Solid understanding of smart contract security, common attack vectors, and adversarial protocol behavior.

• In-depth knowledge of EVM execution, gas optimization, transaction mechanics, and protocol composability.

• Capability to analyze financial mechanisms and convert them into precise technical implementations.

• Familiarity with Foundry, Hardhat, or similar smart contract development tools.

• Strong emphasis on testing discipline, including unit, integration, fuzz, invariant, and/or fork testing.

• Proficient in working with on-chain data and blockchain analytics.

• Solid software engineering fundamentals and the ability to work independently on intricate technical challenges.

• Valuable experience in DeFi protocol design or mechanism design, insurance, risk markets, prediction markets, financial derivatives, liquidity management, capital efficiency, automated market makers, pricing mechanisms, yield optimization, automated vault strategies, asset management protocols, risk modeling, quantitative finance, MEV, transaction-ordering dynamics, cross-chain protocols, messaging, oracle design, manipulation resistance, protocol monitoring, risk infrastructure, systems managing over $100M in TVL or transaction volume, or substantial contributions to major open-source DeFi protocols.

🏝️ Benefits
