OKX - Rust Developer, Exchange OS Trading Engine

• Design and build a unified account and matching system that supports Perpetuals, Spot, and Prediction Markets — including on-chain order matching, cross-margin validation, settlement, and liquidation/risk engines (ADL, ADL-avoidance, ADL waterfall, ecosystem insurance fund mechanics). • Build and optimize the core components of ExchangeOS: the staking/venue-creation framework that allows KYC-verified institutions and Web3 protocols to launch and operate their own dex on shared infrastructure. • ExchangeOS • Drive performance engineering across the stack — parallel transaction execution, low-latency order pipelines, and throughput/latency optimization at the engine and chain level. • Track cutting-edge blockchain and trading-system technology (e.g. Hyperliquid, dYdX, other high-performance perp DEX architectures) and apply best practices to our infrastructure. • Partner with product and business teams to translate venue/exchange requirements into technical designs, and provide ongoing technical support. • What We Look For In You • Strong proficiency in Rust, with hands-on experience in high-performance, low-latency systems; experience with parallel/concurrent execution engines is a strong plus. • Deep understanding of exchange/matching engine mechanics: order book design, margin systems, liquidation and ADL, settlement, and risk engines — familiarity with perpetual, spot, or prediction market products is a strong plus. • Solid grounding in blockchain fundamentals (consensus, P2P networking, cryptography); experience reading core code of major L1/L2 systems (Ethereum, Optimism, Arbitrum, or high-performance L1s like Hyperliquid/Solana) is a plus but not the primary focus of this role. • Strong systems-performance mindset: profiling, memory/allocator tuning, and designing for sub-millisecond latency at scale. • Excellent teamwork, communication, and logical reasoning skills; genuine passion for trading systems and blockchain technology.
