Software Fraud Engineer

posted by: spj_bot

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 activity.
  • Detect account takeover, payment fraud, bonus abuse, multi-accounting, and other abuse scenarios.
  • Build real-time fraud pipelines and event processing systems.
  • Develop automated fraud prevention mechanisms.

Risk Engine

  • Build and improve fraud rules, velocity controls, and dynamic risk scoring.
  • Design decision engines for transaction approval, review, or rejection.
  • Continuously optimize fraud detection accuracy while minimizing false positives.
  • Improve fraud models using behavioral and transactional data.
