As the Senior Frontend Engineer, you will build a high-performance, real-time /"Mission Control/" dashboard. Users will watch live call transcripts stream in, see agents thinking in real- time, and intervene if necessary.

You will ensure that the UI gracefully handles data segregation for thousands of sub-accounts, implementing /"Switch Account/" features similar to modern SaaS platforms (e.g., Vercel, AWS).● Complex State Management:You will manage the complex local state of the application using Zustand or TanStack Query. You will ensure the UI stays in sync with the high-velocity backend state managed by Temporal, implementing /"Optimistic UI/" patterns where appropriate to make the app feel instant.● Visualizing Voice Data:You will implement visualizations for voice data, such as audio waveforms, call sentiment analysis charts (using Recharts or Visx), and real-time connectivity status indicators.● Demo-Ready Polish:We are launching at a global event. You have a keen eye for UX/UI polish. You will implement smooth animations (Framer Motion) and responsive designs that look spectacular on a demo screen, ensuring the product /"feels/" as advanced as the AI behind it.Technical Skills & Requirements● Must-Have (The MVP Stack):○ 5+ years of frontend experience, with deep expertise in Next.js (App Router), React, TypeScript, and Tailwind CSS.○ Real-Time Data: Extensive experience with WebSockets (Socket.io or raw), Server-Sent Events (SSE), and handling high-frequency data updates in the UI.
