Frontend 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
