## About the Role

* 3 to 6 years of professional software engineering experience, including backend services you have shipped and owned in production.
 * 1+ years of production experience in Golang, or strong experience in another backend language and real enthusiasm for picking Go up quickly.
 * A working understanding of low-latency, high-throughput distributed systems. Real-time decisioning comes with a latency budget, and you are keen to learn to build inside one.
 * Hands-on experience with SQL and/or NoSQL databases, and some exposure to event-driven architectures (Kafka or similar).
 * Willingness to operate what you build, including a share of on-call, with a pragmatic approach to reliability.
 * Uses AI tooling in day-to-day development and can critically evaluate its output for correctness and quality.
Nice to have

 * Experience in fraud, risk, payments, lending, or financial crime, especially money movement fraud, bank account linking fraud, payout abuse, or lending fraud.
 * Experience with rules engines, real-time feature stores, or ML model serving in a decisioning path.
 * Background in Kotlin, Java, Python, or Node.js alongside Go.
 * Familiarity with cloud infrastructure (AWS, GCP).
 * Experience working across multiple brands, regions, or regulatory regimes.
What we value

 * A product-oriented mindset. You think beyond the ticket, understand the "why" behind the work, and take a high level of responsibility for outcomes rather than output.
 * Comfort with ambiguity. This is a new team on a new surface; parts of the charter are still being drawn, and you will help draw them.
 * A track record of owning a project or feature end to end, especially in fast-paced environments.
 * Clear and proactive communication, with a collaborative spirit. We work across three companies and several time zones, so we move fast, but we succeed together.
 * An adversarial instinct. The best fraud engineers enjoy thinking like the attacker.

## Description

* Design fraud detection and automated enforcement for our financial products end to end: from signal collection through to the decision that blocks a fraudulent payout.
 * Build on and extend our shared fraud decisioning platform, so signals, rules, and models work across all three of our brands instead of being rebuilt three times.
 * Partner closely with risk analysts, data scientists, and product managers to turn observed fraud patterns into shipped detection, and to know when a rule, a model, or a product change is the right answer.
 * Work across team boundaries with our account security, payments fraud, and financial product teams. We build on their signals rather than rebuild them, so clean interfaces matter.
 * Contribute to architectural discussions and technical decisions as we establish the fraud infrastructure baseline for financial products, with support from senior engineers on the team.
 * Write well-tested, observable code and help the team hold a high quality bar. In fraud, a silent failure is a loss event., We believe in equality of opportunity and welcome candidates from all backgrounds regardless of age, gender, ethnicity, disability, sexual orientation, gender identity, socio-economic background, religion, or belief.
