Intern, Application Support Engineer I at Flywire1

Are you ready to keep the world's money moving? At Flywire, our Payments Platform processes billions of dollars across 240+ countries — and when something goes wrong, payers can't pay, clients can't get paid, and the business stops. That's where Application Support comes in. We are the team that keeps the platform running: investigating production issues, partnering with Engineering to fix root causes, and turning recurring pain into permanent improvements. We are looking for Fly-terns (4º year students) in Valencia to join the Application Support team this summer. You won't just be "shadowing" — you'll be working on real production issues and building tooling that makes our team faster, smarter, and more proactive. The Role: Project-Driven & Supported As a Fly-tern in Application Support, you will be embedded within our team and participate in our day-to-day rituals — triage, ticket reviews, incident handling — while focusing on 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 Application Support engineer for day-to-day guidance, pair-debugging sessions, and code reviews. • A Manager: To support your professional growth, provide feedback, and help you navigate the Flywire culture. What You'll Work On Application Support sits at the intersection of engineering, product and operations, so your project can dive deep into very different technical areas. Possible domains include: • Support Tooling & Automation: Building internal tools (Ruby/Python) and integrations that reduce manual work — auto-triage scripts, ticket enrichers, self-service runbooks, or operational dashboards used by the team every day. • Observability & Insights: Designing dashboards and alerts on top of our payments data (Sumo Logic, Jira, MySQL, MongoDB) to surface recurring issues, escalation patterns, or SLA risks before they become incidents. • AI-Augmented Support: Helping us push the boundaries of how Application Support uses AI — from automated investigation agents to AI-assisted ticket categorization and knowledge base generation from past resolutions. • Root-Cause Engineering: Pairing with the team on a recurring class of production issues — from data inconsistencies in the global ledger to integration failures with banking partners — and shipping the fix end-to-end with our Engineering squads. AI-Augmented Engineering Application Support is one of the most AI-forward teams at Flywire. As an intern, you will learn to leverage cutting-edge AI tools like Cursor, Claude Code and Gemini to investigate issues faster, draft runbooks, query logs, and build internal automations. We treat AI as a teammate, and we'll teach you how to get the most out of it.
