We are At Cross River, we're building the financial infrastructure that powers global innovation. With our cutting-edge suite of embedded payments, cards, and lending solutions, we enable millions of businesses and consumers to transact seamlessly and securely. With 900+ employees worldwide and an R&D center of over 160 employees in Jerusalem - we’re reshaping how financial technology is developed and delivered. .

The Role:
We are seeking a frontend engineer who can craft intuitive, high?performance web applications that unlock generative?AI capabilities for our customers and internal teams. You will build reactive, data?driven UIs—chat experiences, content editors, dashboards—that integrate with our GenAI backend services (Node.js on AWS) to deliver secure, accessible, and delightful user experiences.

Who You Are:

* Experienced building streaming chat or collaborative editing UIs (e.g., using WebSocket or WebRTC).
* Familiarity with vector?search UX patterns (semantic search bars, result ranking visualizations).
* Had Exposure to design systems (Storybook) and Figma collaboration.
* Has Knowledge of authentication patterns (OAuth, Cognito) and secure client?side storage.
* Background in data visualization (Recharts, D3) for AI analytics dashboards.

What You’ll Actually Be Doing:

* Design and implement responsive web applications using React (Next.js) and TypeScript that surface chat, summarization, and creative?assist features powered by LLMs.
* Integrate securely with backend GenAI APIs (REST/GraphQL, WebSocket) and handle real?time streaming of model responses.
* Build reusable UI components (TailwindCSS/shadcn/ui) and design systems for prompt inputs, context panes, and feedback collectors.
* Implement client?side observability (OpenTelemetry, Sentry) to monitor latency, errors, and usability of GenAI features.
* Optimize performance through code?splitting, server?side rendering (SSR), and efficient state management (React Query, Zustand, or Redux Toolkit).
* Collaborate with product designers and ML/backend engineers to iterate on prompt engineering, UI/UX flows, and evaluation loops.
* Champion accessibility (WCAG 2.1 AA), localization, and responsive design to reach global audiences.

Why You’ll Love Working Here:
We’re a collaborative, humble, and fast-paced team that takes pride in building real solutions to real problems. You’ll work on meaningful products that empower businesses and people, alongside curious, supportive teammates who are always up for a challenge. Innovation and ownership are part of our DNA—and we’re just getting started.

Next Step:
Hit Apply. Bring your AI vibes. We’ll bring the challenge - and the snacks.
