• Own critical infrastructure components such as ledgers, transaction logs, wallet management, and settlement workflows
• Build internal APIs used by other product teams for monetization, checkout, and reporting
• Focus on security, compliance (e.g. PCI, GDPR), and observability
• Collaborate cross-functionally with Product, Finance, Legal, and other engineering teams
• Mentor engineers and contribute to a culture of technical excellence

Requirements:

• 5+ years of experience as a back-end engineer building production systems
• Strong hands-on experience with Node.js (NestJS – a strong advantage)
• Proven experience designing and maintaining distributed systems or microservices architectures
• Solid understanding of event-driven architectures and asynchronous processing
• Deep knowledge of API design, performance optimization, and security best practices
• Experience working with relational and NoSQL databases (e.g. PostgreSQL, Redis)

• Strong testing discipline, including unit, integration, and E2E tests
• Strong English communication skills

Nice to Have:

• Experience with payment systems, financial flows compliance-sensitive domains.
