We are looking for a versatile Full Stack Engineer who loves building robust systems and seeing them come to life through functional, high-impact user interfaces. As part of the Payments Team, you’ll build the “Mission Control” that powers our global money movement. You will bridge the gap between complex backend logic (Java/Python) and real-world results using JavaScript and Retool. This is the perfect role for an engineer who wants to own problems end-to-end: from the database to the UI that catches a payment anomaly and empowers our operations teams to move faster. What You’ll Do Build the "Control Center": Use Retool and JavaScript to create powerful internal tools and dashboards that turn complex data into actionable workflows for operators worldwide. Power the Platform: Contribute to and maintain the APIs and backend logic (Java/Python) that drive transaction lifecycles. Architect Data Flow: Partner with peers to ensure data moves securely and efficiently from core services to our internal interfaces, maintaining high standards for data integrity and speed. Embrace Modern Dev: Leverage agentic development and pragmatic tools to accelerate how we build, iterate, and automate complex payment workflows. Solve Real Problems: Troubleshoot system bottlenecks and build smarter tools that help our teams catch issues and move payments faster. What You Bring to the Table A "User-First" Mindset: You are passionate about building experiences that solve real-world headaches for your colleagues and customers. Full Stack Curiosity: Whether your "home base" is Java/SQL or JavaScript/UI , you aren't afraid to dive into the other side of the stack to get a feature across the finish line. Pragmatism: You believe "Done is Better than Perfect." You know when to write a perfect abstraction and when to use Retool to ship a working tool today. Systems Thinking: You don’t just "map data"; you want to understand the business logic of how money moves and how to handle it gracefully when things go wrong. Collaborative Spirit: You enjoy talking through ideas with Product Managers and Ops teams to find the best path forward. Bonus Points FinTech Experience: You’ve worked in environments where data integrity is mission-critical. Tooling Expertise: Experience with Retool or building internal-facing applications. Deep Data: An interest in Postgres or experience with data schemas. If you want to join us in our journey to help break barriers in financial access and improve lives globally, there's no better place or time to join. Our global team of 800+ people is spread across six continents. We aspire to hire the best mix of people from former Olympians to YouTube influencers and we speak over twenty languages. This incredible diversity isn't a bonus; it's the engine that lets us serve the world. Ready to Apply? Let’s Go.
