Descripción de la vacante

Cloudflare is seeking a Senior Software Engineer for the Internal Fraud Platform in Austin, TX. You will build and operate services that ingest fraud signals from internal systems, design pipelines, and deliver data to analysts for investigation and action.

You will partner with data scientists to productionize models, shape the platform architecture, and drive end-to-end ownership of critical fraud signals with scalable, reliable systems.

Formación

• 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.

Responsabilidades

• 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.
