About this role

About the Role

Are you an aspiring engineer looking to bridge the gap between classroom theory and real-world impact? We are looking for a Software Engineering Intern with a Fullstack mindset to join our team for at least 6 months.
In this role, you won't just be watching from the sidelines. You will be an active contributor to the systems powering our Fiat and Stablecoin payment rails. This internship is designed to give you 360-degree exposure to product development—from crafting intuitive user interfaces to building the robust backend logic that handles financial transactions. You’ll work alongside experienced mentors who are committed to your growth in a fast-paced, fintech environment.

What You Will Do

Build End-to-End: Develop and ship features across the entire stack, working on both the user-facing web applications and the underlying payment services.
Backend Support: Help build and maintain payment flows
Frontend Development: Craft responsive and user-friendly interfaces using React, TypeScript, or JavaScript.
Collaborate: Work closely with product managers and senior engineers to turn wireframes and requirements into functional code.
Code Quality: Learn to write "production-ready" code by participating in code reviews and applying industry-standard testing practices.
Problem Solve: Debug issues across the stack and help optimize our systems for performance and security.

What We Are Looking For

Current Student or Recent Grad: Currently pursuing (or recently completed) a degree in Computer Science, Software Engineering, or a related technical field.
Fullstack Curiosity: You have a foundational understanding of both frontend (HTML/CSS/JS) and backend development.
Language Agnostic: You’ve tinkered with at least one backend language (e.g., Python, Go, Ruby, Java) and are eager to learn our specific tech stack.
Database Basics: A fundamental understanding of SQL and how data is structured.
Tools: Familiarity with Git for version control.
Mindset: A "can-do" attitude, a strong desire to learn, and the ability to communicate your ideas clearly.
Bonus Points: An interest in Fintech, Crypto, or how money moves globally.
