Binance offerings range from trading and finance to education, research, payments, institutional services, Web3 features, and more. We leverage the power of digital assets and blockchain to build an inclusive financial ecosystem to advance the freedom of money and improve financial access for people around the world.
We are looking for a Java Backend Engineer to join our P2P trading platform team. This role focuses on building and scaling a high-volume C2C marketplace — the backend that powers a peer-to-peer trading experience similar to consumer resale platforms, but for financial assets.
Responsibilities
- Design and develop core backend modules for the P2P marketplace: order matching, escrow, dispute resolution, merchant management
- Build high-concurrency transaction processing systems capable of handling large-scale C2C order flows
- Develop seller/buyer workflow systems including listing management, order lifecycle, and payment confirmation
- Integrate with payment channels and internal systems for fund locking and release
- Ensure system reliability, idempotency, and consistency across the full transaction lifecycle
- Participate in architecture design, code reviews, and cross-team technical collaboration
Requirements
- 3–5 years of Java backend development experience
- Proficiency in Spring Boot, MyBatis, and distributed system components (Redis, MQ, MySQL)
- Experience building e-commerce, C2C marketplace, or trading platform backends
- Understanding of order lifecycle management, escrow/fund-hold mechanisms, and dispute workflows
- English communication skills
- Experience at C2C/e-commerce companies is a strong plus
Why Binance
• Shape the future with the world’s leading blockchain ecosystem
• Collaborate with world-class talent in a user-centric global organization with a flat structure
• Tackle unique, fast-paced projects with autonomy in an innovative environment
• Thrive in a results-driven workplace with opportunities for career growth and continuous learning
• Competitive salary and company benefits
• Work-from-home arrangement (the arrangement may vary depending on the work nature of the business team)
