Support Crypto Integrations: Add support for new cryptocurrencies by developing modules that handle blockchain interaction, transaction validation, and wallet communication.
Implement Regulatory Logic: Translate AML/KYC requirements and transaction limit policies into backend logic that enforces compliance across the platform.
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.
Ability to thrive in a small team and fast-paced startup environment.
Excellent communication skills and a collaborative mindset.
Base Salary Range: $100,000 - $120,000 USD
For all United States based opportunities, our comprehensive benefits package includes, for all full-time employees, competitive health, dental, and vision insurance plans through BlueCross BlueShield (employer subsidized), a generous retirement savings plan with company match up to 4%, performance based bonuses and paid time off.
Working at CoinFlip means collaborating with experienced and innovative leaders who share a clear vision and a track record of success. We offer a collaborative and positive working environment where we encourage employees to balance productivity with time to recharge.
