Job Responsibilities:

• Design, build, and maintain a multi-chain DEX aggregation stack: routing and quoting engine (multi-pool, multi-path, multi-hop), AMM + RFQ/intent mixing, and cross-chain bridging with unified settlement.
• Implement and optimize smart contracts for batch transactions, multicall, signature/Permit2 flows, limits/RFQ, settlement, and risk controls with strong gas efficiency (Solidity; plus for Yul/assembly).
• Integrate major liquidity venues and services: Uniswap v2/v3, Curve, 0x/1inch/ParaSwap/CoW, Chainlink/Pyth, and bridges/messaging (e.g., LayerZero/Wormhole/Axelar).
• Mitigate MEV: private relays, batch auction/solver flows, signature protections, tx simulation, and protected routing.
• Ship developer-facing APIs/SDKs (TypeScript/Node, viem/ethers) and ensure low-latency, reliable browser execution.
• Build simulation and risk tooling: price impact and slippage models, revert/rollback strategies, retries; leverage Foundry/Tenderly for mainnet-fork testing.
• Establish observability and SLOs: p95 latency, price improvement, fill success rate, revert rate, gas per fill, cross-chain success rate.
• Collaborate with security: apply static/fuzz/property testing (Slither/Echidna), support audits, and remediate findings.

Qualifications：

• 3+ years in software engineering; 2+ years in DeFi/market making/routing/aggregation.
• Proficient in Solidity; comfortable with Rust/TypeScript. Strong with viem/ethers, Foundry, Tenderly, Slither/Echidna.
• Deep understanding of DEX/AMM mechanics and pathfinding/slippage control.
• Experience with cross-chain bridges/messaging and failure/reorg handling strategies.
• Practical MEV knowledge and mitigation techniques in production.
• Bonus: Solana/Anchor, Move, CosmWasm, performance analytics (ClickHouse/TSDB), browser extensions.
