[Remote] Senior Software Engineer - Settlement

Note: The job is a remote job and is open to candidates in USA. Cari Network is building a blockchain-based payment system for real-time movement of digital money across traditional finance and digital assets. The Senior Software Engineer - Settlement will own platform components end to end, including bank-facing dashboards, TypeScript services, interbank settlement workflows, and integrations, while improving production reliability and partner adoption.

Responsibilities

• 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
• Comply with all Cari information security policies, including the Acceptable Use Policy, and complete required security awareness training
• Protect the confidentiality, integrity, and availability of Cari systems and data, including bank-partner and customer information, consistent with least-privilege access principles

• 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)

• 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 (e.g., Restate)
• Hands-on experience with cloud infrastructure, containerization, and deployment orchestration (e.g., AWS, Docker, Kubernetes)
• Mature CI/CD and testing practice — GitHub Actions, node-tap on the backend and Vitest on the front end, and meaningful test coverage
• Experience working with banking systems, fintech infrastructure, payment products, or interbank settlement mechanics
• Familiarity with ACH, wires, RTP, FedNow, or other bank payment rails
• Experience with observability, tracing, or audit logging in financial systems
• Exposure to security and compliance expectations in regulated environments
