React/Java Lead Fullstack Engineer - Lead Software Engineer

The Role: Leading Fraud Defense with AI

As a Lead Engineer within the Payments Trust & Safety group, you will spearhead the development of scalable security solutions designed to thwart fraudulent activity. This isn't a traditional manual coding role; you are expected to apply creative problem-solving and AI-enhanced workflows to protect global financial transactions at scale.

Tech Stack & Vibe Integration

You’ll be working with a robust enterprise stack including React, TypeScript, and Java/Springboot on AWS infrastructure. What sets this role apart is the explicit mandate to drive "vibe coding" practices—utilizing tools like GitHub Copilot to accelerate code reviews, refactoring, and testing strategies. You will be responsible for validating AI outputs to ensure they meet the rigorous security and performance standards required in high-stakes finance.

Growth & Leadership

This is a unique opportunity to define the AI-assisted engineering culture at a premier global financial institution. Beyond architecture and design, you will coach other engineers on the responsible adoption of AI tools, balancing rapid delivery with the firm’s commitment to stability and security.
