Job Description:
Participate in building next-generation cross-chain DeFi infrastructure with primary responsibilities including:
- Designing and developing DeFi protocol smart contracts with a focus on security, gas optimization, and upgradability
- Building backend services using TypeScript, including monitoring systems, liquidation bots, and protocol automation tools
- Integrating on-chain foundational services such as oracles (Pyth/Chainlink/Redstone), aggregators, and lending protocols
- Participating in cross-chain integrations across multiple EVM chains, collaborating with bridging and messaging protocols
- Engaging in protocol security reviews and working with third-party audit teams
- Designing smart contract events (Events) with careful consideration for indexing and downstream data consumption needs
Job Requirements:
Basic Requirements:
- 3+ years of Solidity smart contract development experience with mainnet deployment and maintenance
- Familiarity with lending protocol mechanisms (e.g., Aave interest rate models, liquidation mechanisms) and AMM designs (e.g., Uniswap V3 concentrated liquidity)
- Proficiency in Go/TypeScript/Python for backend or toolchain development
- Expertise in Hardhat and/or Foundry, including unit testing, integration testing, and fuzz testing
- Deep understanding of EVM internals: storage layout, gas mechanics, proxy and upgrade patterns
- Experience with static/dynamic analysis tools like Tenderly
- Production environment experience: participation in or maintenance of protocols with TVL ≥ $5M or consistent trading volume
Skills & Attributes:
- Security-first mindset: ability to systematically consider potential attack vectors before writing code
- DeFi-native background: genuine interest in protocol mechanisms, financial design, and tokenomics
- Strong startup adaptability: ability to work efficiently in fast-paced, ambiguous environments
- High self-motivation: capable of independently managing priorities and delivering consistently without heavy supervision
- Excellent collaboration skills: clear communication in remote, cross-timezone teams (synchronous/asynchronous)
Bonus Points:
- Experience with cross-chain messaging protocols (LayerZero/Wormhole/CCTP/CCIP)
- Understanding of MEV and familiarity with Flashbots ecosystem
- Contributions to DeFi/Web3 open-source projects
- Practical experience with mature oracle integration patterns
Benefits:
- Competitive cash compensation + token incentives
- Fully remote work with flexible hours and high autonomy
- Deep involvement in 0→1 DeFi core product development with direct impact on protocol architecture and ecosystem growth
