Who we are:
Flywire is a global payments enablement and software company, founded a decade ago to solve high-stakes, high-value payments in education, using modern technology.
Today, we’ve digitized payments for more than 3,300+ global clients across education, healthcare, travel & B2B, covering more than 240 countries and territories and supporting over 140 currencies. And, we’re just getting started!
With over 1000+ global FlyMates, representing more than 40 nationalities, and in 14 offices world-wide, we’re looking for FlyMates to join the next stage of our journey as we continue to grow.
Are you ready to build the engine that moves the world’s money?
At Flywire, "Platform" is the mission-critical heart of our business. Our Payments Platform is a global network that handles high-value transactions across 240 countries. From the core logic moving funds to the payment experiences that our clients rely on, you’ll be working on the tech that makes global payments feel local.
We are looking for Fly-terns (4º year students) in Valencia to join us this summer. You won't just be "shadowing"—you'll be building software that impacts millions of users and processes billions of dollars.
The Role: Project-Driven & Supported
As a Fly-tern, you will be embedded within a Platform delivery team. While you'll participate in team rituals, your primary focus will be a specific, high-impact project designed for your 6-week journey.
To ensure you grow and succeed, you will have a dedicated support system:
A Mentor: A senior engineer for day-to-day technical guidance, pair programming, and code reviews.
A Manager: To support your professional growth, provide feedback, and help you navigate the Flywire culture.
What You’ll Work On
The Platform is broad, and your project will dive deep into the technical foundations of fintech. Possible domains include:
Payer Services & Experiences: Building the high-performance, accessible, and intuitive user interfaces (React) and the JavaScript SDKs that our clients use to trigger payments.
Core Money Movement: Developing the high-precision backend logic (Ruby/Java) that tracks funds, handles currency exchange, and manages the global ledger.
Banking & Network Integrations: Optimizing the APIs and "pipes" that connect Flywire to financial institutions worldwide.
AI-Augmented Engineering
We believe in using the best tools to build the best software. As an intern, you will learn to leverage cutting-edge AI tools like Claude Code and CodexCursor to accelerate your development, automate repetitive tasks, and focus on solving complex architectural problems.
Here’s What We’re Looking For
- Current student in the 4th year of a Bachelor’s Degree in Computer Science, Software Engineering, AI, or Data Science. We highly value candidates from Double Degrees in Mathematics and Informatics Engineering, as well as specialized degrees in Artificial Intelligence, Data Science, or Informatics Engineering.
Tech Foundations: Familiarity with React (for frontend-focused projects) or Ruby/Java (for backend-focused projects). You should have a solid grasp of data structures and SQL.
The "Platform" Mindset: You are curious about how large-scale systems work, you value robust clean code and testing (TDD), and you enjoy building tools that are used by other developers and millions of payers.
Communication: Fluency in Spanish and a strong working command of English to collaborate with our global teams.
Our Tech Stack
Frontend: React, JavaScript/TypeScript, CSS3 (including our SDK architecture)
Backend: Ruby, on Rails and Java (Spring Boot)
Data/Messaging: PostgreSQL, MySQL, RabbitMQ
AI & Tools: Cursor, Claude Code, Codex, GitLab CI, AWS
What We Offer
Competitive Monthly Stipend: Based on Spain's local market standards.
Flexible June Start: We prioritize your exams; your start date is adaptable.
Valencia Hub Culture: Work from our founding office with a vibrant community of FlyMates.
Global Showcase: Present your project results to engineering leaders across the globe.
Career Growth: Successful Fly-terns are our first priority for full-time Associate roles after graduation.
