Cari - Senior Software Engineer
Requirements
• 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). • 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.
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. • 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.
Benefits
• Competitive base salary, bonus, and equity • 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
