Frontend Engineer

VoisX; Bengaluru; On-site; INR 1,500,000 - 2,100,000; Full time

Job summary

VoisX is seeking a Frontend Engineer to build and maintain UI for the public site and admin console, using React/TypeScript with Next.js and Vite.

You will implement the agent editor and Playground, work from a shared visual system, and ensure accessibility and dark mode are consistent across products.

Qualifications

• 3+ years building production UIs with React and TypeScript.
• Strong CSS fundamentals with Tailwind CSS.
• Experience with Next.js and a Vite-based SPA, or ability to ramp quickly on both.
• Comfortable consuming REST APIs directly — reading OpenAPI/FastAPI docs, handling loading/error states, and dealing with auth.
• An eye for detail: spacing, motion, and empty/error states matter.

Responsibilities

• Build and maintain UI across a Next.js marketing site (static export) and a Vite + React admin console.
• Turn agent configuration, analytics, and billing data into interfaces that are usable under real operational pressure, not just in a demo.
• Implement the agent editor and Playground experience customers use to configure and test voice/chat agents before going live.
• Work directly from design tokens and a shared visual system — dark mode, accessible contrast, and consistent components across products.
• Integrate with a FastAPI backend: REST endpoints, file uploads, and realtime/WebSocket connections for live voice/chat testing.
• Care about build output — the marketing site ships as a static export served from nginx, so runtime assumptions that only work in `next dev` aren't good enough.

Job description

Frontend Engineer

You'll split your time across the products customers and our own team actually touch: the public voisx.ai site, the admin console operators use to configure agents and watch usage, and the in-product agent editor and testing Playground.

React TypeScript Next.js Vite Tailwind CSS

What you’ll do

• Build and maintain UI across a Next.js marketing site (static export) and a Vite + React admin console
• Turn agent configuration, analytics, and billing data into interfaces that are usable under real operational pressure, not just in a demo
• Implement the agent editor and Playground experience customers use to configure and test voice/chat agents before going live
• Work directly from design tokens and a shared visual system — dark mode, accessible contrast, and consistent components across products
• Integrate with a FastAPI backend: REST endpoints, file uploads, and realtime/WebSocket connections for live voice/chat testing
• Care about build output — the marketing site ships as a static export served from nginx, so runtime assumptions that only work in `next dev` aren't good enough

What we’re looking for

• 3+ years building production UIs with React and TypeScript
• Strong CSS fundamentals and hands-on experience with Tailwind CSS (or an equivalent utility-first system)
• Experience with both Next.js and a Vite-based SPA, or ability to ramp quickly on both
• Comfortable consuming REST APIs directly — reading OpenAPI/FastAPI docs, handling loading/error states, and dealing with auth
• An eye for detail: spacing, motion, and empty/error states get the same attention as the happy path

Nice to have

• Experience building admin/ops dashboards (tables, filters, role-based access, analytics charts)
• Experience with static-export or JAMstack deployment constraints
