We’re looking for a Mid-Level UX/UI Front-End Developer to join our product engineering team and help us build, scale, and improve our product. In this role, you’ll bridge the gap between design and technology, ensuring our platform is not only visually stunning but also intuitive and highly performant.
You’ll work hands-on across the frontend using Next.js, taking ownership of the user interface and crafting seamless user experiences that directly impact engagement and business outcomes. You’ll collaborate closely with Product, Design, and other Engineers to transform high-fidelity mockups into clean, accessible, and scalable production code.
Create UI concepts from scratch based on product requirements, references, or ideas (without an existing designer in the team).
Use AI-powered UI tools (Claude, v0.dev, Figma AI, etc.) to accelerate design exploration and prototyping.
Implement UI using Next.js 16+, TypeScript, and Tailwind.
Build reusable component-based UI structures.
Take full ownership of UI delivery - from idea to final implementation.
Implement and manage client-side state and server state using Zustand and TanStack React Query.
Integrate and maintain A/B testing solutions.
Add and maintain UI animations using Framer Motion.
3+ years of hands-on UX/UI Front-End experience in a product or SaaS environment.
Strong experience with modern frontend frameworks — Next.js + TypeScript strongly preferred.
Solid experience with design-to-code implementation using Figma, ensuring pixel-perfect accuracy and responsive layouts.
Working knowledge of state management and API integration to ensure smooth data flow between the UI and backend.
Experience designing and building for conversion, specifically subscription funnels, landing pages, or complex dashboard interfaces.
Excellent attention to detail regarding typography, spacing, and micro-interactions.
Clear, precise written communication — you can articulate design decisions and document component behavior clearly.
Strong ownership mindset — you proactively identify UI polish issues or UX friction points without being told.
Comfortable working remotely in a fast-paced, high-expectation environment.
Fluent English, written and spoken.
Experience with animation libraries (Framer Motion, GSAP) to enhance the user experience.
Familiarity with CI/CD pipelines and how frontend deployments work (GitHub Actions, Vercel).
Experience with web performance optimization and monitoring tools like Sentry or Google Lighthouse.
Knowledge of mobile-first design and PWA (Progressive Web App) principles.
Background in SaaS, fintech, or tools with high-frequency user interactions.
Understanding of SEO best practices for frontend architecture.
