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.\nOKX 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 Team\nWe sit on the front lines of OKX's security and compliance mission. Our charter is to build the flexible, scalable, and intelligent AI systems that detect and prevent identity fraud, account takeover, and large-scale organized abuse - in real time and at the scale of a global financial platform. We own the core identity-risk capabilities that decide, millions of times a day, whether an account can be trusted: identity trust signals, behavioral risk modeling, relationship and cluster intelligence, and face, liveness and document verification. We work shoulder-to-shoulder with Product, Risk, Compliance, and Engineering to turn the hardest adversarial problems in crypto into production-grade defenses that protect good users and the open financial system.\nAbout the Role\nWe are looking for a Senior AI Engineer to design, build, and own key identity-risk and trust models at OKX. You will build models that combine identity verification results, device and geo data, and user behavior into trust and risk signals, and use graph and clustering methods to uncover organized, industrialized fraud. This is an end-to-end, research-to-production role: you will own algorithms in your domain and ship models into real-money, high-risk, large-scale production environments.\nYou will be a hands-on technical contributor who works closely with Product, Risk, and Compliance, and who helps raise the technical bar of the team. Your domains span:\nIdentity trust & risk modeling - fusing verification scores, device, geo, and behavioral data into identity-quality and trust signals.\n\nCluster & relationship intelligence - graph and clustering methods to identify account farms, mass registration, and coordinated attacks.\n\nBehavioral risk modeling - behavioral features and sequence models for account takeover and abnormal-session detection.\n\nBiometric & multimodal signals - face embeddings, liveness/anti-spoofing, DeepFake and injection defense, document forgery and AIGC detection, used as inputs to identity trust and the risk layer.\n\nAI agents - applying agentic AI to scale investigation, detection, and operational defense.\n\nWhat You'll Be Doing\nBuild identity trust & risk models: Design and ship coarse-to-fine risk models that fuse face/liveness/document verification scores, device, IP and geo signals, and behavioral data, for high-concurrency real-time decisioning.\n\nUncover organizedfraudwith graph & clustering: Build entity graphs across accounts, devices, faces, documents and templates, and apply community detection, clustering, and GNN methods to detect fraud rings and large-scale abuse.\n\nDevelop behavioral features & sequence models: Engineer real-time and offline behavioral features, and build sequence models to detect account takeover, bot/script behavior, and abnormal sessions.\n\nLeverage biometric & multimodal signals: Turn biometric features (face embeddings, face quality, liveness and anti-spoofing results) and document-forgery and DeepFake signals into reliable identity-trust inputs for risk decisions, including biometric similarity for cross-account linkage and duplicate-identity detection. Work with the face, liveness, and document teams, or build models yourself.\n\nDrive execution & collaboration: Deliver measurable results while managing ambiguity; partner with backend, product, infrastructure, risk, and compliance teams to integrate models into the production decision chain. Own metric definitions, the balance between false positives and missed fraud, pass rate, monitoring, and drift handling.\n\nAdvance applied R&D: Experiment with graph learning, multimodal fusion, and AI agents; stay current with academic and industry advances and translate them into practical defenses.\n\nRaise the technical bar: Contribute to design reviews, share applied-AI best practices, and mentor junior engineers.\n\nWhat We Look For\n5+ years of hands-on experience building risk-control, fraud-detection, or identity-trust models, including significant experience deploying ML systems into production.\n\nGraph & clustering expertise: Experience applying graph mining, community detection, clustering, or GNN methods to fraud or abuse detection.\n\nBehavioral modeling: Solid experience with behavioral feature engineering and sequence modeling, including real-time feature pipelines.\n\nDeep AI/ML expertise: Strong proficiency with PyTorch and/or TensorFlow, and solid experience with production ML systems.\n\nStrong technical & coding skills: Strong coding ability (e.g., Python, SQL) and the system-level thinking to design end-to-end solutions with high availability and low latency.\n\nAdversarial mindset: Understanding of how fraudsters adapt, and how to evaluate and iterate defenses against evolving attacks.\n\nCollaboration: Strong communication skills, with experience working across engineering, product, and risk teams.\n\nEducation: Bachelor's degree or higher in Computer Science, Electrical Engineering, or a related field.\n\nPreferred Qualifications\nExperience in identity verification, KYC/KYB, AML, face-payment or payment risk control, or biometric security.\n\nHands-on experience with face recognition, liveness/anti-spoofing, OCR, document parsing, fake-ID detection, or media forensics.\n\nExperience with graph databases or graph computing (e.g., Neo4j, GraphX) and real-time graph features.\n\nKnowledge of data and AI/ML infrastructure (e.g., Spark, Flink, Kafka, Airflow, Snowflake).\n\nFamiliarity with MLOps best practices: monitoring, retraining, and continuous improvement of production models.\n\nExperience with LLMs and AI agents.\n\nExperience working in fast-paced technology companies or security-critical environments.\n\nResearch publications, patents, or open-source contributions in relevant AI fields.\n\n Perks & Benefits\nCompetitive total compensation package\nL&D programs and Education subsidy for employees' growth and development\nVarious team building programs and company events\nWellness and meal allowances\nComprehensive healthcare schemes for employees and dependants\nMore that we love to tell you along the process!\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.
