Location: Hybrid About Us At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company. At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in. Available Locations: Austin, TX Role Summary As a Product Security Engineer, you will support security assessments and vulnerability operations for Cloudflare’s core software products. In this role, you will analyze system architecture, threat model new features, and ensure that product-related security findings are accurately triaged, routed to the correct engineering owners, and mitigated within our SLAs. On any given day, you might conduct a deep-dive security review on a new feature design, triage a complex bug bounty submission, or work directly with engineering teams to resolve vulnerabilities from different sources like bug bounties, SAST, fuzzing and penetration tests. You will also work autonomously to identify areas where our manual processes slow down. You will write code and integrate AI/LLM solutions to automate initial triage and data enrichment, building tools that help the team handle security findings at scale. In short, your work will sit at the intersection of Product Security, Vulnerability Operations, and internal AI Tooling. Ideally, you have experience in conducting academic/vulnerability research with a focus on systems security. Responsibilities Implement AI Security Solutions: Identify process bottlenecks and build AI-driven tools or scripts to help automate code analysis, optimize triage, and streamline Product Security workflows. Security Reviews & Threat Modeling: Conduct structured security reviews and threat modeling sessions (e.g., STRIDE) across product features, defining security requirements early in the development lifecycle. Product Vulnerability Management: Manage the operational lifecycle of product security findings. Ensure vulnerabilities are verified, mapped to the correct engineering owner, and tracked to mitigation in alignment with established SLAs. Bug Bounty Triage: Perform the technical triage and validation of Cloudflare’s external Bug Bounty submissions, verifying exploitability and evaluating business risk. Pentest Coordination: Support internal and external penetration testing engagements by reviewing findings, clarifying technical context, and assisting development teams with remediation strategies. Engineering Collaboration: Partner closely with DevOps and product teams, acting as a reliable security point of contact and helping developers implement secure coding practices. Desirable Skills, Knowledge, and Experience Product/AppSec Expertise: 5+ years of experience in Product or Application Security within large-scale distributed cloud environments or SaaS platforms. Practical AI & Automation Engineering: Demonstrated ability to build production-grade automation scripts and tools. Must possess hands-on engineering experience leveraging AI/LLMs to solve operational or technical challenges. Threat Modeling & Risk Analysis: Competency in threat modeling methodologies and the ability to evaluate code flaws to determine their actual engineering and security impact. Vulnerability Lifecycle Operations: Experience tracking, routing, and driving the remediation of software vulnerabilities across engineering groups while working against defined SLAs. Strong Collaboration & Communication: Ability to collaborate effectively across teams, clearly communicating technical security risks to software engineers and resolving ownership ambiguity constructively. Bonus points Offensive Security Tooling: Familiarity with modern exploitation techniques, fuzzing frameworks, or automated scanning utilities. Program Management Experience: Experience scaling crowdsourced security programs (e.g., HackerOne, Bugcrowd) or optimizing agile project management workflows within JIRA. Experience in integrating hardware security features into production code bases Equity This role is eligible to participate in Cloudflare’s equity plan.

Across 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. 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, y ou'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. Nice to Haves Security engineering experience at a top-tier internet company, cloud provider, or leading security vendor You've led 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 Shipped AI + Security work — security copilots, intelligent rule generation, automated analysis, or remediation recommendation systems Perks & Benefits Competitive total compensation package L&D programs and Education subsidy for employees' growth and development Various team building programs and company events Wellness and meal allowances Comprehensive healthcare schemes for employees and dependants More that we love to tell you along the process!

Location: Ho Chi Minh City, Vietnam Insurance is one of the world's largest industries and one of the most painful to interact with . Paper forms. Sluggish call centres. Three-week underwriting cycles. Claims that vanish into queues. We are rebuilding all of it on top of a modern platform and AI agents that actually do the work, not pretend to. You will not be picking up tickets. You will be deciding what to build, prototyping it on Monday, shipping a draft to a real customer by Friday, and improving it from real usage. We expect you to push the product, the codebase, and the way we work. Why This Role Exists We are looking for someone who treats AI as a creative material, not a feature on a roadmap. The next year of insurance is being defined right now. What gets automated, what gets reimagined, what gets thrown out. We want builders who want to be in that room and ship the answer. The team is small. The mandate is large. If your highest-energy work has historically come from solving real problems end to end, this is the seat. What You Will Do Own outcomes, not tickets. Pick the biggest lever for our customers each sprint and drive it to live. Surface the next one yourself. Build with AI as a primary tool, not a chatbot bolt-on. OCR, document understanding, generation, agent loops, evaluation harnesses. You decide where each fits. Ship prototypes fast, then make them production-grade. A working demo on day three beats a perfect plan on day ten. Work directly with customers. You will see real claims, real underwriting screens, real broker workflows. You will watch users hit dead ends and decide what to fix. Raise the bar on the codebase. Reviews, refactors, testability, observability. Not as policy, as habit. Push the team forward. Skills, agents, internal tools, engineering standards. Propose them, build them, get them adopted. Who You Are You ship. Ideas without execution do not count for you. High agency. You do not wait for a card to be assigned. You see what is worth doing and you start. Strong opinions, loosely held. You make calls with incomplete information and change your mind when the evidence shifts. Curious about the domain. Insurance is messy and full of weird incentives. That intrigues you, not annoys you. Fluent with AI. You have shipped something real with LLMs or agents. You know where the magic ends and where you have to engineer carefully. Care about humans on the other end. Insurance done right gives people peace of mind in their worst weeks. That is the point. Your Toolbox We use Node.js + TypeScript + Nest.js on the back end, Vue (and some React) on the front end, GraphQL, MongoDB, Docker, AWS. AI work spans OpenAI, Anthropic, Google, plus a growing set of in-house skills and agents. You do not need to have used every piece. You do need to be the kind of engineer who picks up a new tool and is shipping with it within the week. What We Expect at This Level 6+ years building production systems. Track record of complex, customer-facing software shipped, not just maintained. Real AI experience. You have built and shipped at least one substantive AI-driven feature. POCs that died in a notebook do not count here. Strong fundamentals. OO, design patterns, testing, web security, performance. You do not need a refresher. Cloud comfort. AWS, Azure, or GCP. At least one in depth, the rest enough to hold a conversation. Communication. You can explain a tradeoff to a non-technical stakeholder in two minutes and to an engineer in one. Not Suitable for the Role If… You prefer tickets assigned to you over choosing what to build. You measure your work in lines of code, not outcomes. You see AI as a buzzword to put on your CV rather than a tool you have actually used in anger. You want a process-heavy environment with detailed specs handed down from product. You are looking for a maintenance role on a finished platform. Why CoverGo Insurance is the rare industry where AI can save people hours of their worst weeks. We are already shipping AI-powered claims, underwriting, distribution, and document automation to enterprise carriers across five continents. The platform is real. The customers are real.
