We are looking for a Backend Engineer to build and scale the high-performance systems powering a global Checkout product and next-generation payments infrastructure.
This role focuses on designing APIs, services, and distributed systems that handle payments, settlement, asset conversion, identity verification, and multi-chain transaction routing. You will play a key role in building fault-tolerant, low-latency infrastructure that supports both web2 and web3 use cases at scale.
Responsibilities:
- Design, build, and maintain high-performance APIs and backend services for the payments platform.
- Develop and evolve systems supporting payments, settlement, transaction routing, asset conversion, and identity/security workflows across multiple chains and providers.
- Build backend features that directly improve product performance, reliability, and conversion for dApps and partners.
- Participate in system design, architecture discussions, and incident response to ensure high availability, scalability, and fault tolerance.
- Write clean, maintainable, and well-tested code, contributing to code reviews and engineering best practices.
- Continuously optimize system performance, latency, and reliability across the infrastructure.
Requirements:
- Strong experience building production-grade backend systems using a modern programming language (TypeScript preferred; Go or Rust acceptable).
- Deep understanding of distributed systems, API design, and database architecture.
- Hands-on experience with cloud infrastructure and containerization tools (e.g., AWS, Docker, Kubernetes).
- Strong computer science fundamentals, including algorithms, data structures, and system design.
- Ability to communicate effectively in English (primary working language).
Nice to Have:
- Experience in payments, fintech infrastructure, or high-throughput transactional systems.
- Familiarity with blockchain technologies, smart contracts, or DeFi protocols.
- Experience with event-driven architectures and real-time data processing systems.
- Contributions to open-source projects or technical writing in backend, infrastructure, or crypto domains.
- Evidence of exceptional achievement in any domain (e.g., competitive programming, open-source, athletics).
