About the Job

Requirements

Strong computer science and security fundamentals, including deep understanding of operating systems, networking, compilers and the Java Virtual Machine, distributed systems, application security, cloud-native security, and supply chain security.
Expert-level Java proficiency, with hands-on depth in the Java Virtual Machine, ClassLoader, Java Agent, ASM, ByteBuddy, bytecode instrumentation, and performance profiling and tuning; working proficiency in Python or Go.
Substantial production experience with RASP, SAST, DAST, IAST, SCA, image security, and code scanning, including designing capabilities, integrating engines, building platforms around them, and scaling them independently.
Offensive and defensive security experience covering root causes, exploitation paths, detection logic, bypass techniques, and fixes for common web, API, and microservices vulnerabilities.
Fluency with large language models and AI Agents, including model capability limits, agent architecture, tool calling, context engineering, evaluation methods, and AI's security implications and effect on the attack surface.
Ability to lead the design and delivery of security products, platform modules, and SDKs/Agents while balancing security outcomes against performance overhead, integration cost, and long-term operability.
Ownership, cross-team communication, and persistence to move security governance, rule enforcement, and remediation through to a clear result.

Responsibilities

Architect and build the end-to-end DevSecOps platform and the SDKs/Agents behind security products, covering code, build, artifacts, images, deployment, and runtime.
Lead runtime protection through RASP and Java Agent, including bytecode instrumentation, runtime hooking, and detection/interception engines using ASM, ByteBuddy, and Instrumentation, with continuous performance, stability, and compatibility tuning.
Integrate and productise scanning capabilities across SAST, DAST, IAST, SCA, code scanning, and image scanning; embed tools such as SonarQube and Coverity into CI/CD and close the loop from detection through blocking, remediation, and re-test.
Design detection, remediation, hardening, and counter-measures for XSS, SQL injection, SSRF, deserialisation, command execution, authentication/authorisation flaws, and API security.
Apply LLMs and AI Agents to vulnerability analysis, rule generation, false-positive attribution, remediation guidance, security knowledge capture, and engineering automation; build a coherent view of architecture, mechanics, and security implications.
Embed as the security technical expert inside engineering teams, driving security standards, onboarding specifications, release gates, risk tiering, and remediation mechanisms that measurably improve security baseline and delivery quality.
Partner across engineering, architecture, SRE, QA, and business teams on priority projects, solving difficult security problems and turning solutions into reusable platform capabilities and repeatable practices.

Desired Qualifications

Security engineering experience at a top-tier internet company, cloud provider, or leading security vendor.
Experience leading the build of a DevSecOps platform, application security platform, RASP, code scanning platform, or cloud-native security platform.
Background in security product development, SDK/Agent engineering, vulnerability research, red team exercises, or purple team work.
Experience shipping AI + Security work such as security copilots, intelligent rule generation, automated analysis, or remediation recommendation systems.

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.

About the Opportunity

As a Staff Engineer, you'll own the build-out of our security engineering and DevSecOps capabilities: designing and developing the security products, platform services, and SDKs/Agents that embed protection directly into how code is written, built, shipped, and run.

This is a role for someone with real depth in security, broad coverage across the stack, and the engineering muscle to ship. Just as important is the ability to drive adoption — security that lands in complex, fast-moving business environments rather than sitting in a policy document.

What You’ll Be Doing

Architect and build our end-to-end DevSecOps platform and the SDKs/Agents behind our security products, covering code, build, artifacts, images, deployment, and runtime.
Lead runtime protection through RASP and Java Agent — bytecode instrumentation, runtime hooking, and detection/interception engines using ASM, ByteBuddy, and Instrumentation, with continuous tuning for performance, stability, and compatibility.
Integrate and productise scanning capabilities across SAST, DAST, IAST, SCA, code scanning, and image scanning. You'll embed tools like SonarQube and Coverity deep into CI/CD and close the loop from detection through blocking, remediation, and re-test.
Go deep on application security offence and defence — designing detection, remediation, hardening, and counter-measures for XSS, SQL injection, SSRF, deserialisation, command execution, authentication/authorisation flaws, and API security.
Bring AI-native security engineering to life. Apply LLMs and AI Agents to vulnerability analysis, rule generation, false-positive attribution, remediation guidance, security knowledge capture, and engineering automation — and build a coherent view of the architecture, mechanics, and security implications.
Embed as the security technical expert inside engineering teams, driving security standards, onboarding specifications, release gates, risk tiering, and remediation mechanisms that measurably lift the security baseline and delivery quality.
Partner across engineering, architecture, SRE, QA, and business teams on priority projects, solving the genuinely hard security problems and turning the solutions into reusable platform capability and repeatable practice.

What We Look For In You

Strong computer science and security fundamentals — deep understanding of operating systems, networking, compilers and the JVM, distributed systems, application security, cloud-native security, and supply chain security. Both breadth and depth.
Expert-level Java, with hands-on depth in the JVM, ClassLoader, Java Agent, ASM, ByteBuddy, bytecode instrumentation, and performance profiling and tuning. Plus working proficiency in Python or Go.
Substantial production experience with RASP, SAST, DAST, IAST, SCA, image security, and code scanning — enough to design a capability, integrate the engine, build the platform around it, and take it to scale independently.
Real offensive and defensive experience. You understand the root causes, exploitation paths, detection logic, bypass techniques, and fixes for common web, API, and microservices vulnerabilities — and can design from both the attacker's and defender's point of view.
Fluency with LLMs and AI Agents, including a considered view on model capability limits, agent architecture, tool calling, context engineering, evaluation methods, and how AI is reshaping both security engineering and the attack surface.
Strong engineering execution paired with product instinct — able to lead the design and delivery of security products, platform modules, and SDKs/Agents while balancing security outcomes against performance overhead, integration cost, and long-term operability.
Exceptional ownership, cross-team communication, and the persistence to move security governance, rule enforcement, and remediation through to a clear result.
