In the rapidly evolving world of cryptocurrency and Web3, security is not just a feature — it’s the foundation. As one of the leading crypto exchanges globally, OKX continues to push the boundaries of innovation while ensuring the highest standards of platform integrity and user protection. If you're passionate about building robust, scalable security systems that defend millions of users daily, the Staff Security Engineer role offers a unique opportunity to shape the future of digital asset safety.
Why Security Matters in Crypto
Cryptocurrency platforms face relentless threats — from sophisticated phishing attacks and smart contract exploits to large-scale DDoS campaigns and insider risks. With millions of active users and high-value transactions occurring around the clock, securing every layer of the infrastructure is critical. The Staff Security Engineer plays a central role in designing and maintaining backend systems that proactively detect, prevent, and respond to these threats.
At OKX, security isn’t siloed — it’s embedded into every product decision, development cycle, and operational process. This role sits at the intersection of engineering excellence and cybersecurity strategy, working closely with product, design, and engineering teams to ensure that security scales seamlessly with growth.

Core Responsibilities
As a Staff Security Engineer at OKX, your work will directly impact the resilience and trustworthiness of one of the most widely used crypto ecosystems in the world.
Designing Secure Backend Systems
You’ll lead the architecture and implementation of backend systems for the client security team. These systems power critical functions such as authentication safeguards, session management, anomaly detection, and real-time threat mitigation. Your designs must support high availability, low latency, and seamless integration across multiple services.
Building Big Data Analytics for Threat Intelligence
Security operations today rely heavily on data. You'll develop and maintain big data analytics platforms using technologies like Flink and Kafka to process massive volumes of logs, user behavior patterns, and network traffic in real time. These insights fuel automated risk scoring, fraud detection models, and incident response workflows.
Proactive Risk Assessment & System Optimization
Beyond development, you'll collaborate cross-functionally to identify potential vulnerabilities in new features or existing systems. Through threat modeling, code reviews, and red-teaming exercises, you'll help embed security best practices early in the development lifecycle.
You’ll also be responsible for optimizing system performance under heavy load, ensuring that security controls don’t compromise user experience — a delicate balance in high-throughput environments.
