Job description

Responsibilities

The Global Payment Tech team is the core engine powering ByteDance's global payment and financial services, spanning payment acquiring, wallets, financial products, insurance, and foreign exchange for users and merchants worldwide. We span engineering, data, and AI, building high-concurrency, highly available systems across multi-currency, multi-market complexity, and embedding AI into risk control, credit decisioning, and operations automation. You will grow cross-disciplinary expertise at the intersection of payments, finance, and AI.

About the Team Our team is responsible for providing ByteDance’s global users and merchants with a first-class payment experience by building a strong and robust infrastructure and platform to support fast product iteration and key feature development. Global Payments powers payment capabilities across multiple ByteDance international business lines.

As an intern on this team, you won’t be working on a side project built to be thrown away. You’ll be given a scoped, real piece of the payment product, paired with a dedicated mentor, and supported through onboarding, design review, and code review until your work ships. By the end of the internship, you’ll have shipped code that real users and merchants depend on, and you’ll understand how payment needs differ across global markets.

We encourage a culture of self-driven, intellectual curiosity, openness and problem-solving. We are looking for talented individuals to join us for an internship. Our internship program offers students hands‑on experience, industry exposure, and opportunities to apply their knowledge to real‑world challenges while building a strong foundation for personal and professional growth.

Interns will gain practical experience, explore potential career paths, and participate in social events, learning programs, and development workshops alongside industry professionals. Candidates may apply to a maximum of two positions across Our Company and its affiliates globally.

What You’ll Do

• Own a scoped project within Global Payments, from technical design through implementation, testing, and launch
• Work alongside your mentor and the wider team to build and improve payment features across web and client platforms
• Learn to navigate and contribute to a large, mature codebase — reading existing code, tracing behavior, and making changes that fit the surrounding patterns
• Write well-tested code and clear documentation, and learn why correctness and reliability standards are higher in payments than in most domains
• Participate in code reviews, technical discussions, and team rituals as a full member of the team
