Frontend Engineer (Web App, React, Real-Time UX, Media Flows)

Other Jobs To Apply

No other job posts for this day.

We are hiring a Frontend Engineer to build a polished, fast, and reliable web experience for an AI-enabled product. This is not a marketing site role. It is a real product UI with media capture, uploads, dashboards, and tight workflows. We will share full product context on a call. What you will build A modern web app (mobile-first) with two primary experiences: Candidate-style flow: guided steps, media capture/upload, progress states, results view, survey capture. Employer-style dashboard: list views, detail views, replay/preview, score breakdown, exports, and simple admin controls. A clean “branding layer” to support: Two branded experiences One limited white-label experience (theme, logo, copy) without exploding scope A tight, repeatable configuration-driven UI workflow so we can update scenarios and screens without constant rework. Real-time friendly UI patterns (loading states, turn-taking, latency-safe UX) as we evolve. Must have Strong React experience (Next.js preferred). Excellent UI engineering fundamentals: component design, state management, data fetching, performance tuning. Experience handling media flows in browser: camera/mic permissions video/audio recording large file uploads with progress + retry playback UX Comfortable working with REST APIs (or GraphQL) and auth flows (magic link, email login, or OAuth style patterns). Strong attention to UX details and edge cases. Nice to have Experience with WebRTC or streaming UX patterns. Experience with dashboards and data-heavy UI (tables, filters, exports). Familiarity with Tailwind, shadcn/ui, or a clean design system approach. Experience with basic security and privacy UI patterns (consents, data access boundaries, signed URLs). What you will do in the first 2 to 4 weeks Implement the core product UI skeleton and navigation for both user types. Build the media capture and upload experience with excellent reliability and progress states. Build the results screen and dashboard screens with clean reusable components. Implement white-label theming in a controlled way (no scope creep). Add QA-friendly instrumentation and error handling so issues are visible and debuggable. How we work Short sprints with frequent demos. We move fast, but we do not ship messy UX. You will work closely with backend and AI engineers to align UI, APIs, and workflows. To apply, include 2 to 3 examples of product UIs you built (dashboards, media capture, uploads, or complex flows). A short note on your experience with browser recording and large uploads. Your preferred stack for a scalable Next.js frontend (routing, state, API layer, error handling). Screening questions Have you built browser-based video/audio recording before? What were the biggest issues and how did you solve them? How do you handle large file uploads reliably (progress, retry, resume, failures)? What’s your approach to building a controlled white-label theming system without making the UI unmaintainable? What frontend architecture patterns do you prefer for product apps (state management, API layer, component design)? If you look strong on paper, we will do a short call and share the full product context. Important Notice: Please do not message Tim directly. All applications and questions must be sent to Ahmed, the hiring lead, through this Upwork job post and message thread only. Anyone who reaches out via LinkedIn or any other third party channel will be rejected and reported on Upwork. Apply tot his job Apply tot his job
