Summary
Build next-generation fraud prevention technology that protects digital users and transactions. You will design real-time detection pipelines, risk engines, dynamic scoring, and automated decision services for scenarios such as account takeover and payment abuse. The role combines software engineering with behavioral and transactional data analysis while optimizing detection accuracy and false-positive rates.
Highlights
Engineering-focused fraud prevention role building real-time detection systems, risk engines, automated decisions, and behavioral controls. The position offers challenging work at the intersection of software engineering, payments, security, and data-driven risk management.
Description
We're looking for a Software Fraud Engineer to design and build our next-generation fraud prevention platform.
You'll develop real-time fraud detection systems, risk engines, and automated decision-making services that protect both our users and business.
This is an engineering role focused on building fraud prevention systems — not a manual fraud operations position.
Responsibilities
Fraud Detection
Design and develop fraud detection systems for payments, wallets, authentication, and user activityDetect account takeover, payment fraud, bonus abuse, multi-accounting, and other abuse scenariosBuild real-time fraud pipelines and event processing systemsDevelop automated fraud prevention mechanisms
Risk Engine
Build and improve fraud rules, velocity controls, and dynamic risk scoringDesign decision engines for transaction approval, review, or rejectionContinuously optimize fraud detection accuracy while minimizing false positivesImprove fraud models using behavioral and transactional data
Data & Analytics
Analyze transaction patterns, user behavior, device intelligence, and risk signalsWork with large-scale event streams and transactional datasetsCreate internal investigation and monitoring tools for Fraud, Support, and Compliance teamsInvestigate emerging fraud patterns and rapidly deploy countermeasures
Engineering
Develop scalable backend services supporting fraud preventionBuild APIs and internal tooling for risk evaluationOptimize latency for real-time fraud decisionsCollaborate closely with Product, Payments, Data, and Platform teams
