Fronend Engineer

You will build the interfaces that agency operators use every single day — dashboards, Kanban boards, Gantt charts, time tracking widgets, workflow builders, analytics views, and client portals. Kontrora's frontend is Next.js 15 with the App Router, TypeScript, Tailwind CSS 4, and shadcn/ui. The product is complex and data-dense, which means you need to care deeply about performance, accessibility, and the small details that make a tool feel fast and satisfying. You will work closely with the product designer and backend engineers, and you will have real ownership over the component library.

Responsibilities

Implement UI components and pages with pixel-perfect accuracy from Figma designs
Build and maintain the shared component library using shadcn/ui and Tailwind CSS 4
Optimize frontend performance: bundle size, Core Web Vitals, rendering strategies (SSR, SSG, client)
Write accessible, semantic HTML — ARIA roles, keyboard navigation, screen reader support
Implement complex interactive features: drag-and-drop (dnd-kit), data visualization (Recharts, D3), workflow canvas (xyflow/react)
Manage client-side state with Jotai and server state with SWR
Write unit and integration tests for components and user flows
Collaborate with backend engineers on API contracts and data shapes

Requirements

3+ years of professional frontend development experience
Expert React and TypeScript skills — hooks, context, memoization, and rendering deeply
Strong CSS skills including Tailwind, animations, and responsive design
Experience with Next.js App Router and understanding of server vs. client components
Web performance knowledge and accessibility experience building WCAG-compliant interfaces

Nice to Have

Experience with Tailwind CSS 4 and design token systems
Framer Motion or animation library experience
Experience building data-heavy dashboards or analytics UIs
Familiarity with xyflow/react or node-based canvas libraries
