Resumo da oferta

Cari is building a blockchain-based payment network and seeks a generalist backend engineer to own major pieces of the platform end-to-end. You will develop the bank-facing dashboards, TypeScript services, and interbank settlement workflows, while enabling secure, reliable bank integrations.

You will work with product, design, DevOps, and partner teams to ship in production, maintain data integrity in PostgreSQL, and improve tooling, testing, and observability for a small, fast-moving team.

Qualificações

• 5+ years of experience building production software, with a focus on backend services and cloud application architecture.
• Strong expertise in TypeScript across both the front end and the back end.
• Deep experience with React, modern component architecture, state management patterns, and data-heavy workflows.
• Solid Node.js experience building REST APIs and event-driven services (we use Fastify on Node 24).
• Comfort owning a feature from schema to UI
• Experience with asynchronous workflows, webhooks, and keeping UI state in sync with backend transaction states.
• Experience building responsive, polished, high-quality user interfaces for complex workflows.
• Strong product sense and attention to usability, implementation quality, and maintainability.
• Experience with cloud application architecture, microservices, event-driven messaging (e.g., Kafka), and durable workflow orchestration (Restate).

Responsabilidades

• Build and evolve our bank-facing management dashboard: bank onboarding, user and role management (RBAC), transaction monitoring, settlement operations, interbank book transfer tracking, and developer tooling such as API keys and webhooks.
• Design and ship the TypeScript backend services that power those experiences — orchestration, bank, transaction, bilateral netting, and settlement APIs.
• Build and maintain integrations with bank partners and third-party platforms, including provider adapters, webhook-driven flows, and real-time event updates.
• Model and evolve the PostgreSQL schemas behind core banking entities, with the correctness and auditability of financial data demands.
• Raise the engineering bar: automated testing, CI/CD, observability, release engineering, and deployment practices in collaboration with DevOps that let a small team ship safely and often.
• Work with product and design to turn tokenization complexity into familiar banking primitives rather than crypto concepts.
• Write the documentation, integration guides, and reference implementations that let bank partners adopt Cari without hand-holding.
