Blockchain Engineer ‑ Copy-Trade Protocol

Mission:Emit immutable trade clones at the speed of mempools. Engineer on-chain vault + relay contracts that ingest master signals, laser-bridge them across EVM chains, and absorb slippage, MEV, and NFL Sunday-level volatility without exposing followers to liquidation contagion. Stack & Level Requirements - Solidity 0.8.25+ via Foundry toolchain (Forge, Anvil, Cast) or Rust/Anchor on Solana - Proficiency: Huff / Yul inlines for gas micro-optimisations, EIP-712 signing, EIP-1167 minimal proxies - Cross-layer bridges: LayerZero, Wormhole, CCIP + custom relayers for <2 s finality - MEV-Geth style searchers – understand sandwich mechanics to architect commit-reveal patterned entry pools - Price oracles: Chainlink CCIP-read, Pyth, custom tick-level fallback for sub-$0.05 deviation error in volatility freak events - Security toolkit: Slither, Mythril, Echidna fuzz 1e6 vars/run, invariant bracelets as code - Gas profiling: forge-std Vm for on-chain gas snapshots pre-per-release hook Hard-Check Trader DNA ⚔️ You have personally executed >$10 k notional on perpetuals & on-chain or cross-margined DeFi strategies with stress traces or Etherscan proof of addr. ⚔️ You’ve felt (or caused) impermanent loss >10 % in a single block. ⚔️ Optional but revered: vault or strategy on DeFiLlama/Apeboard with >$50 k TVL linked to your keys. Responsibilities - Build gas-constrained e2e testnets atop Anvil mainnet fork for every release candidate. - Continuous white-hat review loop – both formal (Certora specs) & red-team bounty (Immunefi). - Coordinate with backend for off-chain signatures (EIP-712 typedData balancers). - Draft governance & upgrade timelocks (OpenZeppelin UUPS). - Be on-call for on-chain incidents (failed Oracle, stuck bridge, keeper tottering). with protocol parameters YAML files. Soft Enemies – Don’t apply - ifYou only deployed ERC-20 tokens and never** felt liquidation missiles. - You ignore MEV game theory. Perks / Weapons Cache - Hardware fund: Apple M Max + 64 GB RAM, 10 Gbps fibre hookup. - Personal copy-trading gas allowance 1 k USD monthly – trade openly on testnet, share P&L in public. - Health stipend for red-eye debugging—includes premium dark-coffee & builder-milk. - Additional 1 % of inflation-scheduled supply upon achieving $100 m copy-AUM on ETH L2. Apply Now Attach: - Your latest CV. - Etherscan link to your most brutal trading bot / vault (& TVL proof). - GitHub repo (>20 stars) or archived PR of previous audited live contract address. - Recorded deep-dive Loom of <180 s showing circuit breaker you built. Cut-over: Applications stack-ranked & closed within 7 calendar days or when 3 offers signed—whichever happens first. Ready to ship settlement layer blood sport? 💥☠
