OKX is also a trusted brand by hundreds of large institutions seeking access to crypto markets. We are safe and reliable, backed by our Proof of Reserves.\nAcross our multiple offices globally, we are united by our core principles: We Before Me, Do the Right Thing, and Get Things Done. These shared values drive our culture, shape our processes, and foster a friendly, rewarding, and diverse environment for every OK-er. OKX is part of OKG, a group that brings the value of Blockchain to users around the world, through our leading products OKX, OKX Wallet, OKLink and more.\nAbout the Opportunity\nWe are looking for an experienced blockchain developer to join our team building the next generation of high-performance on-chain trading infrastructure. You will help design and implement a unified trading engine - supporting Perpetuals, Spot, and Prediction Markets under a single margin account - and contribute to ExchangeOS, an infrastructure layer that lets KYC'd institutions and Web3 entities stake to create and operate their own trading venues (DEXs) on top of our chain.\nWhat You’ll Be Doing\nDesign 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).\n\nBuild 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.\n\nDrive performance engineering across the stack - parallel transaction execution, low-latency order pipelines, and throughput/latency optimization at the engine and chain level.\n\nTrack cutting-edge blockchain and trading-system technology (e.g. Hyperliquid, dYdX, other high-performance perp DEX architectures) and apply best practices to our infrastructure.\n\nPartner with product and business teams to translate venue/exchange requirements into technical designs, and provide ongoing technical support.\n\nWhat We Look For In You\nStrong proficiency in Rust, with hands-on experience in high-performance, low-latency systems; experience with parallel/concurrent execution engines is a strong plus.\n\nDeep 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.\n\nSolid 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.\n\nStrong systems-performance mindset: profiling, memory/allocator tuning, and designing for sub-millisecond latency at scale.\n\nExcellent teamwork, communication, and logical reasoning skills; genuine passion for trading systems and blockchain technology. \n\nPerks & Benefits \nCompetitive total compensation package\n\nL&D programs and Education subsidy for employees' growth and development\n\nVarious team building programs and company events\n\nWellness and meal allowances \n\nComprehensive healthcare schemes for employees and dependants\n\nMore that we love to tell you along the process!\n\nNotice:\nAll official OKXvacancies are published on this website.While roles may appear on selected third-party platforms from time to time, information on other sites may be inaccurate or outdated.
