Apply Now

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. About the Role Cloudflare's Internal Fraud Platform team is focused on protecting Cloudflare from fraud and abuse: fraudulent signups, promo and trial abuse, payment fraud, chargebacks, and account takeover that cost the company revenue and support overhead. Today the team is built around data science, developing the signals and models that detect this activity. We're hiring our first software engineer to build the platform around that work: ingesting events from the internal systems where fraud shows up (billing, signup, support), evaluating and routing them, and getting decisions and case data in front of the people who act on them. As the founding engineer on this team, you'll be the connective tissue between Cloudflare's internal systems and our fraud detection capabilities. You'll instrument the systems that generate fraud signals, build the pipelines and services that deliver those signals for evaluation, and create the tools our analysts use to investigate and resolve cases. You'll partner closely with data scientists to take models and heuristics from notebook to production, and have meaningful influence over the architecture, tooling, and engineering practices it's built on. Responsibilities Build the Platform: Design, build, and operate the services and pipelines that ingest fraud-relevant events from internal systems (billing, signup, support, and others), evaluate them, and route decisions and case data to the right destinations. Deliver Signals for Scoring: Partner with the team's Data Scientists and Machine Learning Engineer to expose the event data and contextual features their models need, and integrate model decisions back into the pipelines and tools that act on them. Build Investigation Tooling: Create the internal tools and workflows that let Trust & Safety, Support, and Finance analysts investigate flagged accounts and events and take action. Own Projects End to End: Drive initiatives from problem definition through design, implementation, rollout, and operation with minimal oversight. In many ways this is a 0-to-1 team, and you'll be expected to fill in the gaps. Ensure Accuracy and Reliability: Build fault-tolerant systems that handle retries, failures, and high event volumes without silently dropping or duplicating fraud signals, and maintain the operational health of what you ship, including addressing the root cause of recurring issues. Shape Technical Direction: As one of the team's first engineers, help establish the architecture patterns, tooling choices, and engineering standards that will scale as the team grows. Collaborate Cross-Functionally: Work with Trust & Safety, Data Science, Billing/Fintech, Support, and Product teams to understand fraud vectors and turn them into engineering requirements. Desirable Skills, Knowledge, and Experience Five or more years of professional software engineering experience, or equivalent practical experience. Experience building and operating distributed systems or backend services in production. Experience designing and building data or event pipelines (e.g., Kafka, Pub/Sub, or similar). Strong understanding of RESTful APIs, service security, and API standards such as OpenAPI, OAuth, or JWT. Working knowledge of SQL, data modeling, and relational databases such as PostgreSQL or MySQL. Comfort owning ambiguous, 0-to-1 problems with limited existing infrastructure or precedent. Strong troubleshooting, cross-functional communication, and project ownership skills. Bonus Points Experience in fraud, risk, trust & safety, or payments engineering. Familiarity with ML serving and feature engineering concepts Experience with billing, subscriptions, or other financial/transactional systems. Experience building internal tools or dashboards for non-engineering stakeholders (analysts, support, finance). Compensation Compensation may be adjusted depending on work location.

Available Locations: Austin, TX or London, UK (Hybrid) About the Role R2 is Cloudflare's object storage platform, offering developers durable, reliable storage with zero egress fees that integrates seamlessly with Cloudflare's global network and Developer Platform. The R2 Gateway team owns the request-facing layer of R2 — the S3-compatible API gateway that every object put, get, list, and delete flows through. When a customer or application talks to R2, they talk to the systems we build and operate. R2 is growing rapidly, and the gateway must evolve to keep pace. The team is responsible for the API surface that handles authentication, request routing, rate limiting, and coordination between clients and R2's storage and metadata layers — all while maintaining strict compatibility with the S3 API and delivering low-latency, highly available access at global scale. You'll be joining a team that operates at the intersection of large-scale distributed systems, storage infrastructure, and edge computing — building request-path systems that need to be correct, fast, and reliable on every single call. Responsibilities Design, implement, and operate the S3-compatible API gateway that serves every R2 operation, ensuring correctness, low latency, and compatibility with the S3 API surface. Build and operate production services on Cloudflare Workers and Kubernetes that handle high-throughput request traffic with strong availability and durability guarantees. Own the request path end to end — authentication, authorization, routing, rate limiting, and error handling — and the interfaces between the gateway and R2's storage and metadata layers. Own projects end to end: from design docs through implementation, testing, deployment, and production monitoring. Continuously improve the reliability, performance, and observability of the gateway; ramp quickly into unfamiliar and legacy code paths and reduce operational toil. Participate in on-call rotations, drive incident resolution, and write postmortems that raise reliability standards. Use AI tools extensively to accelerate development, debugging, and operational tasks. We expect engineers to leverage AI as a core part of their workflow. Collaborate across teams (storage infrastructure, metadata, networking, other platform teams) to coordinate API contracts, capacity planning, and cross-cutting initiatives. Desirable Skills, Knowledge, and Experience Strong programming skills in Rust, TypeScript, Go, or similar languages. 3-4 years of experience building or operating large-scale distributed systems on the request path, with strong latency and reliability requirements. Familiarity with cloud infrastructure concepts such as object storage, HTTP/API gateways, edge computing, or service-oriented architectures. Experience designing and operating high-throughput APIs — authentication, routing, rate limiting, and backward-compatible API evolution. Understanding of reliability and observability practices: monitoring, alerting, performance tuning, and incident response. Strong written and verbal communication skills; ability to explain technical decisions clearly and coordinate across teams. Comfortable working with AI coding tools as part of a daily development workflow. Experience with the S3 API surface, or with Cloudflare Workers, Durable Objects, or edge computing platforms, is a strong plus. What Makes Cloudflare Special?

Responsibilities Lead the research, design, and evaluate detection models that identify automated, fraudulent, and malicious activity across Internet-scale data Mentor others in how to uncover patterns and behaviors that distinguish adversaries from legitimate users. Own the detection measurement framework, defining metrics and evaluation strategies for problems where ground truth is noisy, delayed, or contested. Drive adoption of promising AI/ML techniques and represent Cloudflare in the broader research community. Drive cross-functional partnerships with ML Engineers, Data Engineers, and Product; Influence roadmaps and align detection strategy with company priorities. Shape long-term detection strategy, identifying gaps and opportunities that span multiple product areas. Desirable Skills, Knowledge, and Experience Fraud and bots at scale. You have experience across fraud, abuse, and/or bot detection on large, high-velocity traffic. You may focus on one, but you transfer instincts between them. Strong fundamentals, fluent in data. You have solid applied statistics, machine learning, and AI methodology fundamentals. You choose the right technique for the problem, and are fluent with large-scale data. You have at least 8-10 years of experience professionally working in Data Science, ML Engineering, or Software Engineering. Demonstrated ability to make ambiguous, high-stakes technical decisions with incomplete information. You are very comfortable with Python & SQL in production environments. Bonus points At home in ground truth ambiguity. Building detections when ground truth is scarce is the heart of this job. You make real progress with weak, delayed, or absent labels and you're energized by adversaries that fight back. You don't burn signals. You understand (or are curious to learn) how to act on detections without tipping your hand, knowing that how you deploy and respond can erode your future visibility. Pragmatic about complexity. You know when a simple solution beats a complex one, and you don't chase small gains at disproportionate cost. Disciplined in code. You apply strong programming and engineering best practices in both research and production code. Impact-driven and clear. You connect your work to business impact and communicate clearly across technical and non-technical stakeholders. Compensation Compensation may be adjusted depending on work location.

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.
