Rust Developer, Exchange OS Trading Engine

As a Rust Developer on the Exchange OS Trading Engine team at OKX, you will design and implement a unified trading engine supporting Perpetuals, Spot, and Prediction Markets under a single margin account. You will contribute to ExchangeOS, an infrastructure layer that enables KYC'd institutions and Web3 entities to stake and operate their own trading venues on OKX's chain.

What you'll do

• 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 and venue-creation framework that allows KYC-verified institutions and Web3 protocols to launch and operate their own DEX on shared infrastructure
• Drive performance engineering across the stack through 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 such as Hyperliquid and dYdX, and apply best practices to the infrastructure
• Partner with product and business teams to translate venue and exchange requirements into technical designs, and provide ongoing technical support

What you bring

• Strong proficiency in Rust, with hands-on experience in high-performance, low-latency systems
• Deep understanding of exchange and matching engine mechanics: order book design, margin systems, liquidation and ADL, settlement, and risk engines
• Solid grounding in blockchain fundamentals including consensus, P2P networking, and cryptography
• A strong systems-performance mindset with expertise in profiling, memory and allocator tuning, and designing for sub-millisecond latency at scale
• Excellent teamwork, communication, and logical reasoning skills, with genuine passion for trading systems and blockchain technology

Nice to have

• Experience with parallel and concurrent execution engines
• Familiarity with perpetual, spot, or prediction market products
• Experience reading core code of major L1/L2 systems such as Ethereum, Optimism, Arbitrum, or high-performance L1s like Hyperliquid and Solana

What we offer

• Competitive total compensation package
• Learning and development programs and education subsidy
• Team building programs and company events
• Wellness and meal allowances
• Comprehensive healthcare schemes for employees and dependants
