🌍 About Our Client

One of our clients is reimagining how money moves around the world.

They're building a global fintech platform that combines the simplicity of a modern banking app with the power of blockchain technology—without exposing users to the complexity of crypto. The goal is simple: make sending, spending, and managing money across borders feel effortless.

Already serving thousands of users in 130+ countries, the company is now accelerating growth after recently raising $5M in seed funding from leading US and European investors.

This is an early-stage company with a lean, high-caliber engineering team where every line of code has a visible impact on the product.

💼 About the Role

This is one of two founding engineering hires and a unique opportunity for a product-minded full-stack engineer who enjoys owning features from end to end.

You'll build across the entire stack—from backend services and APIs to the application layer—working directly with the founders to bring ideas to life. The engineering team believes in shared ownership, so you'll have the freedom to contribute wherever you can create the biggest impact.

If you enjoy solving challenging technical problems while building products users genuinely love, you'll fit right in.

🎯 Who Thrives Here?

We're looking for builders who love ownership, move fast, and enjoy creating products from the ground up.

The strongest candidates are product-minded engineers who care about the user experience just as much as writing great code. Startup experience is highly valued, but curiosity, initiative, and a willingness to learn matter even more.
