Frontend Engineer

*(Remote — North America, LATAM or Europe)* Nango (YC W23\) lets developers build product integrations with AI. It enables applications to connect to the real world through integrations. More than 250 paying customers rely on Nango today, including Replit, Mercor, and Ramp. We are a YC\-backed, multi\-million ARR company with a team of 12 from AWS, GitHub, Okta, Snyk, Netlify, Uber, Samsara, Workato, and more. We are hiring a Senior or Staff Frontend Engineer to join the core engineering team and own the entire frontend experience of Nango's platform. This is a critical role: as a product\-led business selling to developers, the quality of our UI directly reflects our product. You will revamp our dashboard and developer\-facing interfaces end to end, raising them to best\-in\-class standards — from information architecture and interaction design to rendering performance and polish. You will own the frontend from ideation through implementation, working closely with engineering and developer customers. What You'll Do * Rebuild and elevate Nango's dashboard and developer\-facing UI to a best\-in\-class standard, setting the bar for quality and craftsmanship. * Design and implement data\-intensive views (logs, syncs, connection management) that are fast, readable, and a pleasure to use — even at scale. * Own frontend performance: optimize rendering, minimize bundle size, and ensure the UI feels instant. * Build polished, accessible UI components and establish scalable patterns and conventions for the frontend codebase. * Collaborate directly with developer customers to understand pain points and iterate on UX. * Contribute to backend work (Node.js/TypeScript) when needed to unblock yourself or ship a feature end to end — you don't need to be a backend expert, but you're comfortable enough to be autonomous. * Shape the product roadmap and company strategy alongside the founding team, with high ownership of the frontend direction. Who You Are * 5\+ years (senior) or 10\+ years (staff) of frontend engineering experience, with a portfolio or track record of shipping high\-quality, production UIs. * Deep expertise with React, TypeScript, and Tailwind CSS — our core stack. * Proven experience building complex, data\-heavy dashboards or developer tools where performance and UX quality are critical. * Strong sense of UI/UX craft: you obsess over layout, spacing, interaction details, loading states, and edge cases. * Experience with frontend performance optimization — you understand virtual rendering, memoization, lazy loading, bundle analysis, and know when each matters. * Familiarity with backend fundamentals (APIs, databases, Node.js) — enough to be dangerous and self\-sufficient when needed. * Experience at a high\-caliber US\-based tech company or developer tools company. * Passion for developer tools and building outstanding developer experiences. * Strong communicator, proactive, and reliable in a remote\-first environment. * Pragmatic, positive, and low ego: you step up when needed and unblock teammates. * Startup\-ready: autonomous, ownership\-driven, and able to navigate ambiguity. * Based in North America, LATAM, or Europe. If you're a seasoned frontend engineer who builds beautiful, high\-performance developer interfaces, thrives on ownership, and wants to shape the future of integrations — we'd love to hear from you.
