Full Stack Engineer

Role Description

Our Engineering team is growing! 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.

Qualifications

• 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.

Requirements

• 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.

Benefits

• Unlimited annual leave.
• Great healthcare benefits.
• Employee discounts.
