Rust 开发工程师 (L1 Rust Risk Engine Developer)

关键词：Perps、Rust、内存级状态更新、清算引擎（Clearing House)、自动减仓(ADL)、全局清算引擎(Risk Engine)

职位描述：

• 风控合约：在底层协议（DMFP）中硬编码最大杠杆率（Leverage Cap）、总持仓上限（OI Cap）及初始保证金判定逻辑，构建无视外层越权篡改的技术拦截器。
• 标签化隔离清算系统开发：开发多维子账户（Sub-accounts）状态树与自动减仓（ADL）算法，实现爆仓风险在指定 渠道内的物理绝对隔离。
• 自动化保证金管理 (Bond Management)：编写高弹性的物理保证金（Bonded Capital）锁仓与自动清算（Auto-Slash）合约，确保在长尾资产价格跳空闪崩时，作恶者的质押物能零延迟强制执行。
• 极致的安全与gas优化：对高频调用的核心风控合约进行Assembly 级或 EVM 级代码审计与 Gas 优化。

职位要求：

• 综合开发经验：本科及以上学历，计算机、数学等相关专业，4 年以上 智能合约开发经验，至少完整主导过一个知名 DeFi 衍生品（CLOB 订单薄/Perps）或独立开发过知名的高频链下/链上衍生品撮合清算系统，或完整参与Layer 1 公链的虚拟机（如 EVM, Wasm, Move VM）内核改写，
• 技术栈：精通 Rust，对计算机内存分配、有向无环图（DAG）状态更新或分布式并发锁有极其深入的研究。
• 风控常识：精通点对池、全仓/逐仓保证金引擎、自动减仓、以及跨链套利清算机制。
• 安全意识：有对抗黑客攻击（重入、三明治夹子、预言机操纵）的实战防御经验，能够熟练运用 Foundry 等进行高强度单元测试与形式化验证（Formal Verification）。

Job Responsibilites:

• Risk Parameters Hardcoding: Hard code the leverage cap, open-interest cap, and initial margin evaluation logic into the base protocol (DMFP), establishing an absolute cryptographic interceptor impervious to upper-layer manipulation.
• Labeled Liquidation Sub-system Development: Develop multi-dimensional sub-account state trees and auto-deleveraging (ADL) structures to enforce total, physical isolation of liquidation contagion within specified Curator channels.
• Automated Bond Management: Write resilient physical margin (Bonded Capital) locking and auto-slashing contracts, ensuring that malicious or underperforming operators' collateral is forcefully cleared with zero latency during tail-asset price gaps or market crashes.
• Extreme Security & Gas Optimization: Perform stringent assembly-level or EVM-level code audits and extreme gas optimization on frequently invoked core risk-mitigation smart contracts.

Job Requirements:

• Development Experience: 4+ years of professional Web3 smart contract development experience, with a proven track record of spearheading the core codebase of a prominent DeFi derivative platform (CLOB/Perps), LRT protocol, or decentralized Clearing House.
• Core Tech Stack: Professional expertise in Rust.
• Risk Management Foundational Knowledge: Deep operational grasp of peer-to-pool models, cross/isolated margin engines, auto-deleveraging (ADL), and cross-chain arbitrage clearing mechanics.
• Security & Tooling: Practical battle-tested experience in defending against exploits (re-entrancy, sandwich/MEV attacks, oracle manipulation), with mastery of Foundry for high-coverage unit testing and Formal Verification.
