Job description

About Cari

Cari Network is building a blockchain-based payment system powering real-time, 24/7 movement of digital money across the traditional finance and digital asset ecosystems. A pre-launch startup, we’re creating an entirely new category of financial infrastructure that brings cash on chain through tokenization while powering the full spectrum of payments for our network — banks and most importantly, the customers they serve.

About the Role

You will own major parts of the Cari platform end to end — the management dashboards our bank partners use, the TypeScript services behind them, interbank settlement workflows, and the integrations that connect us to bank systems and third-party platforms. This is a generalist role on a small team. You'll move across the stack, take on the highest-leverage problem each quarter, and support services running in production. You'll work closely with product, design, DevOps, and partner-facing teams to make the Cari experience fast to adopt, secure, and reliable for bank partners.

What You'll Do

• 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.

Qualifications

• 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 (e.g., Restate).

Nice to Haves

• 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.
• Experience with theming, white-labeling, and multi-tenant product customization.

What We Offer

• Competitive base salary, bonus, and equity
• Full medical, vision, dental benefits
• 401(k) with company matching
• Flexible PTO in a remote-first environment
• Opportunity to shape a market-defining protocol with an experienced founding team
• Influence over architecture strategy at the earliest stage

Security Responsibilities

Applies to all Cari employees

• 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.
