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 Onchain Data Team\nThe Onchain Data team builds the core data and technology infrastructure behind OKX Web3. We connect to diverse blockchain networks and collect, process, govern, interpret, and serve large-scale onchain data, delivering accurate, real-time, and reliable capabilities to Wallet, DEX, Explorer, Risk, CeFi, and AI products.\nOur scope includes, but is not limited to:\nMulti-chain data ingestion, parsing, computation, and unified data models;\n\nData capabilities for onchain assets, transactions, addresses, tokens, contracts, and projects;\n\nBlockchain explorers, the Project Marketplace, Onchain Data APIs, bots, and agents;\n\nLabels, risk detection, risk-control data, and security investigation capabilities;\n\nDEX trending rankings, token scoring, and other onchain data products;\n\nGlobal multi-region deployment, high-availability architecture, performance optimization, and system reliability;\n\nDeep application of AI in engineering, data analysis, risk investigation, and intelligent operations.\n\nYou will work on challenges involving heterogeneous chains, large-scale data, real-time computation, high concurrency, high availability, data accuracy, and complex cross-functional collaboration. Your work can directly improve user experience, asset security, and business growth.\nWhat You May Work On\nThis is a broad hiring track rather than a single fixed role. Your responsibilities will be matched to your strengths, experience, and interests, and may include one or more of the following:\nDesign, build, and evolve onchain data infrastructure, data services, or business systems, taking ownership of the quality and outcomes of critical modules.\n\nBuild multi-chain ingestion, real-time and batch computation, data governance, search, storage, and serving capabilities, continuously improving data accuracy, completeness, and freshness.\n\nContribute to blockchain explorers, the Project Marketplace, onchain assets, labels, risk control, DEX rankings, token scoring, and related platforms or products.\n\nIdentify critical technical and business problems, make sound judgments, design solutions, coordinate resources, drive execution, and review outcomes.\n\nBuild highly available, high-performance, scalable global systems, while continuously improving reliability, cost efficiency, delivery efficiency, and user experience.\n\nUse AI tools deeply and explore agents, intelligent investigation, engineering automation, and intelligent operations, turning successful practices into reusable team capabilities.\n\nCollaborate with product, data, security, algorithm, operations, and engineering teams to drive cross-functional initiatives to completion.\n\nWhat We Value Most\nHunger - Curiosity and Drive\nYou stay curious about AI, Web3, emerging technologies, and new business domains, and can learn unfamiliar areas quickly.\n\nYou do not wait for instructions when facing a problem; you proactively understand the context, identify solutions, and drive execution.\n\nYou go beyond completing assigned tasks and continue to ask about outcomes, user value, and opportunities for improvement.\n\nCognition - Cognitive Ability and Judgment\nYou can quickly understand complex technical and business problems, build a structured mental model, and identify the core issue and key trade-offs.\n\nWhen information is incomplete or the situation is uncertain, you can form sound judgments based on facts and logical reasoning.\n\nYou can compare the value, cost, risk, and long-term impact of different options, clearly explain your rationale, and turn decisions into executable plans and results.\n\nWhat We Are Looking For\nStrong computer science fundamentals and coding ability in at least one mainstream programming language, such as Java, Go, Python, or C++.\n\nClear logical thinking and strong problem decomposition skills, with the ability to independently solve complex technical or business problems.\n\nHands-on experience in one or more of the following areas:\nBackend and distributed systems;\n\nReal-time or batch data processing, data platforms, search, and storage;\n\nHigh-concurrency, high-availability systems, and reliability engineering;\n\nRisk control, security, strategy, or data analysis;\n\nAI agents, LLM applications, or engineering productivity.\n\nA strong sense of ownership and accountability, with the ability to drive initiatives through to measurable outcomes.\n\nOpen, direct, and effective communication, with a willingness to solve problems across teams.\n\nStrong learning ability and growth potential. We value solid engineering fundamentals, but do not use mastery of one specific framework or middleware stack as the sole hiring criterion.\n\nPreferred Qualifications\nExperience with Web3, public blockchains, onchain data, wallets, DEXs, blockchain explorers, or smart contracts.\n\nFamiliarity with one or more blockchain technology models, such as EVM, UTXO, or Move.\n\nExperience with large-scale data processing, stream processing, databases, messaging systems, caching, or search systems.\n\nExperience in fintech, risk control, security, e-commerce, advertising, recommendation systems, or other complex internet businesses.\n\nProven examples of using AI tools to solve real problems and turning solutions into engineered or scalable capabilities.\n\nAbility to work in English, or experience building global and multi-region systems.\n\nDemonstrated technical judgment, business impact, or zero-to-one ownership in previous projects.\n\nThe Kind of Candidate We Hope to Meet\nYou can clearly explain the most complex problem you have solved, how you formed your judgment, and how you drove the solution to completion.\n\nYou have one or more clear strengths. We do not expect experience in every area, but we value meaningful depth or exceptional potential in at least one direction.\n\nYou are willing to understand users and business context instead of passively receiving requirements.\n\nYou are open to unfamiliar domains and can use AI and team collaboration to close knowledge gaps quickly.\n\nYou remain constructive in changing or uncertain environments and can keep moving work forward.\n\nWhy Join Us\nBuild core onchain data infrastructure for OKX Web3, directly supporting global users and multiple strategic businesses.\n\nWork deeply with diverse blockchain technologies, onchain data systems, and real-world Web3 use cases.\n\nSolve challenging engineering problems involving large-scale data, real-time computation, high availability, and global deployment.\n\nExplore the intersection of AI and Onchain Data, applying frontier technologies to data, risk control, products, and engineering workflows.\n\nOwn meaningful problem spaces with the autonomy to identify issues, make judgments, and drive outcomes end to end.\n\nAccess career opportunities across Mainland China, Hong Kong SAR, and Singapore.\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.
