Smart contract development engineer

We are a blockchain platform in Game area and we need smart development engineer as below:
1. Ethereum Smart Contract Development (Game Contract / DApp Contract).
2. Study the smart contract algorithm in the blockchain field, and sort out the status and advantages and disadvantages of the smart contract technology of the mainstream public chain Upgrade to see actual info-depth study of the smart contract system of the WASM specification, including not limited to smart contract virtual machines and programming languages and specifications such as Ethereum, EOS, NEO.
3. Abstract and define smart contracts based on business segments, form protocol and use smart contracts for protocol validation and testing.
4. Use smart contracts for cross-chain interaction, usage analysis and coding implementation for cross-chain related functions in smart contracts.
5. Use frameworks or languages like web3js/web3j, golang to conduct private chain/test chain verification tests about smart contracts,use truffle and openzeppelin to integrate and optimize existing contracts.
