Enhance Customer Identity Verification: Build or integrate services that facilitate customer ID collection, verification, and validation workflows.
Integrate with User Systems: Work on backend logic that connects to our website and user-facing services, enabling seamless user registration, login, and account management.
Drive Technical Strategy: Contribute to architectural decisions, evaluate new technologies, and help shape best practices within the backend team.
Collaborate Across Teams: Work closely with product managers, compliance specialists, blockchain experts, and frontend developers to deliver end-to-end solutions.
Qualifications:
Strong experience with Java, especially in backend service or component-based development.
Solid understanding of service loaders and modular design patterns.
Familiarity with blockchain concepts and cryptocurrency protocols is a plus.
Experience implementing KYC/AML workflows or working in regulated environments is highly desirable.
Working knowledge of RESTful APIs, databases, and integration with third-party services.
