We 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 abuse — in real time and at the scale of a global financial platform. We own the core security AI capabilities that decide, millions of times a day, whether a user is who they claim to be: face and liveness intelligence, document and identity verification, and multimodal risk modeling. 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.
We are looking for a Senior Staff AI Engineer to take a technical leadership role in designing, evolving, and owning OKX’s core security AI capabilities. This is an end-to-end, research-to-production role: you will set technical direction, own algorithms across multiple high-impact domains, and ship models into real-money, high-risk, large-scale production environments.
You will operate as both a hands-on technical contributor and an applied-science leader — driving complex cross-team initiatives, mentoring senior engineers, and ensuring our AI solutions are robust, efficient, and aligned with company strategy. Your domains span:
•
Face intelligence & liveness detection — defenses against presentation attacks, injection attacks, and DeepFakes.
•
Image & video quality assessment — reliable, security-critical decisions across diverse devices, environments, and network conditions.
•
Document understanding & OCR — identity document parsing and FakeID detection for verification and compliance use cases.
•
Multimodal risk & identity intelligence — fusing visual, behavioral, and contextual signals into identity-quality and trust signals.
•
AI agents — applying agentic AI to scale investigation, detection, and operational defense.
