• Build and maintain user-facing and internal APIs for interacting with wallets, quotes, and transactions
• Ensure data consistency and robustness in distributed, multi-tenant environments
• Contribute to React-based frontend interfaces
• Write high-quality, secure, and testable code following clean architecture principles

What We’re Looking For

• 5+ years of experience as a software engineer
• Product-driven mindset with a strong sense of ownership and accountability for delivered outcomes
• Proven ability to design and build scalable, maintainable backend systems
• Strong understanding of distributed architectures, asynchronous processing, and event-driven design
• Experience integrating with external APIs (especially payments, wallets, exchanges, banking)
• Proficiency with relational databases and caching/queueing solutions
• Comfortable collaborating on frontend applications to deliver end-to-end solutions
• Strong attention to code quality, architecture, and security

Bonus Points For

• Real-world experience building fintech or crypto platforms
• Blockchain technology knowledge
• Knowledge of secure multi-tenant SaaS platforms
• Familiarity with Google Cloud Platform or similar cloud providers
• Contributions to payment orchestration, quote engines, or settlement flows
• Understanding of eventual consistency and webhook-driven design
• Experience with technologies such as NestJS, Redis, MySQL, BullMQ, React, and Next.js.

What We Offer

• Impactful work: Build a real fintech infrastructure used in production
• Ownership & Growth: High autonomy and opportunity to grow into a lead architect or system owner
• Modern stack: NestJS, TypeORM, MySQL, Redis, BullMQ, React
• Competitive senior-level compensation, based on experience and impact
• 20+ days of paid time off per year
