## Job description

Remote · Europe / Latam · Full Time · Individual Contributor · +5 Years of Experience Senior Web Developer

## Who We Are

Yuno is the AI-native operating system of global commerce, powering the financial infrastructure of enterprise merchants, banks, and wallets. Through a single API, Yuno connects them to pay-ins, payouts, fraud prevention, KYC/KYB, and stablecoins globally, so they can operate everywhere. Agnostic by design and connected to 1,000+ payment methods and 460+ integrations in 190+ countries, Yuno optimizes acceptance rates, reduces costs, and strengthens security through specialized AI agents that learn from every transaction. Global brands including McDonald's, NetEase Games, GoFundMe, and Rappi run their payments on Yuno.

## About The Role

Yuno is looking for a Senior Web Developer to build the SDK, design system, and web components that power how third parties integrate with our platform. You'll own the developer-facing surface of Yuno's single API — the reusable components and SDKs that merchants, banks, and partners embed into their own products across browsers, frameworks, and environments. This is a role where developer experience is the product: the quality, performance, and consistency of what you ship directly shape how easily the world connects to Yuno. How AI Shows Up in This Role AI is our default execution layer — you'll use AI-assisted tools like Claude Code, Cursor, and GitHub Copilot, and LLMs more broadly, across design, implementation, debugging, testing, documentation, and code review as standard practice, not novelty You'll help shape how the engineering team works with AI, building workflows with AI agents and MCP servers and defining AI-driven development practices that raise the whole team's leverage The SDKs and components you build are the developer-facing edge of an AI-native payments platform whose agents learn from every transaction on the network

## Your Contribution Will Be

SDK and design system — create the design system and web components used across third-party applications, ensuring SDK compatibility across browsers, frameworks, and integration environments Cross-platform consistency — collaborate with backend and mobile teams so the SDK behaves consistently across every platform and integration Performance and build optimization — design low-latency, high-availability applications and optimize bundle size, tree-shaking, and build performance for SDK distribution Full-stack integration — connect user-facing elements with server-side logic and integrate data storage solutions into cohesive, reliable systems Code quality and security — write reusable, testable, and efficient code, and implement security and data protection throughout Developer experience and releases — maintain high-quality documentation and DX for integrators, and design automated pipelines for publishing and versioning SDK releases What Success Looks Like Within your first 6–12 months, you've shipped SDK components adopted by external integrators, raised the bar on developer experience and documentation, and own the pipeline that publishes and versions Yuno's web SDKs.
