## About the Role

Requirements: 3-6 years of full-stack engineering experience, C# .NET, React or Vue.js, SQL, AWS, daily use of AI coding tools

We are a well-established fintech company operating at global scale, serving both consumers and businesses with currency and payments solutions across multiple markets. Backed by a publicly traded parent company, we are in the middle of a full platform rebuild, modernizing the technology layer behind our core products. We are small enough that your code ships fast and your decisions matter, but large enough that the problems are real-scale and the impact is immediate.

We are looking for a mid-level Full Stack Engineer who likes owning problems end-to-end, from API design and frontend experience through to backend services, production reliability, and launch. You will write code that moves money in production, build and modernize the platform across the stack, and ship customer-facing features as we rebuild our platform layer., * 3-6 years building production web applications end-to-end

 * Strong frontend proficiency in React or Vue.js
 * Strong backend proficiency in C# .NET; other OOP languages welcome such as Java, Kotlin, or Go
 * Solid SQL and relational database fundamentals
 * Production AWS experience, hands-on with SQS, DynamoDB, S3, ECS, and Lambda
 * Writing and maintaining tests as a standard part of how you ship
 * Daily use of agentic coding tools such as Copilot, Cursor, Claude Code, or equivalent

Bonus skills:

 * Payments, FX, or regulated-industry experience
 * Microservices and service-oriented architecture
 * CI/CD and modern deployment practices
 * Caching solutions such as Redis or Memcached
 * API testing tools such as Postman or Bruno
 * Jira and Confluence

## Description

* Build and ship features across the stack spanning onboarding, payment initiation, FX, settlement, and supporting services
 * Own your services in production including reliability, observability, on-call, and incident response
 * Ship customer-facing features from the interface through to the services behind them
 * Partner with product, design, and compliance from problem framing through launch
 * Use agentic AI coding tools like Copilot, Cursor, and Claude Code daily across prototyping, refactoring, testing, and documentation
 * Help modernize the platform by migrating parts of legacy services into the modern stack
