You will build the frontend interface for the Twilio-based voice platform used across all locations.
Phase 1 includes softphone UI, dashboards, real-time monitoring, and admin tools.
Phase 2 includes a visual IVR flow builder developed after MVP launch.
Responsibilities
- Build React/Next.js softphone and dashboards for admins, agents, and managers.
- Integrate Twilio Voice JS SDK for real-time WebRTC calling.
- Implement calling features such as dial/answer, mute, hold, transfer, and device selection.
- Develop dashboards: queue state, agent status, voicemails, recordings, location controls.
- Implement real-time updates using WebSockets (and optionally Twilio Sync).
- Create clean UI/UX with TailwindCSS or shadcn/ui and ensure accessibility.
- Ensure cross-browser WebRTC compatibility (Chrome, Safari, Firefox, Edge).
- Implement authentication (JWT/OAuth) and enforce role-based interfaces.
- Collaborate on backend API design and shared TypeScript models.
- Add Sentry logs and automated UI testing for WebRTC and device errors.
- Phase 2: Build the visual IVR builder using React Flow with versioning, preview, and publishing.
Must-Have Requirements
- 3+ years experience with React and TypeScript; Next.js strongly preferred.
- Hands-on experience integrating Twilio Voice JS SDK or similar WebRTC technologies.
- Strong understanding of WebRTC audio handling, device switching, and echo/noise issues.
- Experience with real-time applications (WebSockets, live dashboards, multi-user states).
- Strong UI/UX implementation skills with TailwindCSS, shadcn/ui, or Material UI.
- Experience consuming REST and WebSocket APIs.
- Knowledge of JWT/OAuth authentication flows.
- Experience with performance optimization and debugging media issues.
- Strong collaboration skills, especially around cross-functional API development.
