Role Description
We are seeking a very senior Backend Engineer with expert-level experience in Node.js, TypeScript, and serverless AWS architecture. You’ll own core backend systems that power our neobank: payments, wallets, secure authentication, event-driven pipelines, and streaming infrastructures.
You’ll work at the intersection of fintech, blockchain, event streaming, and AI, designing mission-critical systems with strong security, compliance, and performance guarantees. This role is ideal for engineers who thrive in fast-moving, high-ownership environments and love pushing what’s possible with AI-assisted development.

- Experience designing secure, compliant financial flows (payments, wallets, KYC, auth, etc.).
- Solid understanding of real-time protocols: WebSockets, SSE.
- Familiarity with stablecoins, blockchain payment flows, or modern payments APIs.
- Able to contribute to React Native when needed (not the main focus).
- Comfortable in an engineering environment where AI is actively used every day.
- Passion for pushing the frontier of AI-driven development, not just adapting to it.
