Senior Front-End Engineer (React & Live Streaming)

About the Role
We are looking for an amazing Senior Front-End Web Developer to join our team and help shape the future of our live streaming experience. In this role, you will lead the development of our user-facing video platforms, building highly responsive, pixel-perfect UI components in React while managing the complex orchestration of real-time data and media streams.
If you love the challenge of bridging beautiful design with deep technical video architectures (like MSE, WebRTC, and HLS players), this is the role for you.
What You’ll Do

·       Build Next-Gen Streaming UI: Architect, develop, and maintain high-performance web applications using React and TypeScript.

·       Optimize Video Playback: Implement and tune player libraries (such as Video.js, Hls.js, or Shaka Player) to ensure seamless, buffer-free playback across devices.

·       Enable Real-Time Interaction: Build ultra-low-latency interactive features including live chat, real-time reactions, and viewer polling using WebSockets or SSE.

·       Drive Media Capture Integration: Develop broadcaster interfaces that leverage browser media APIs to capture high-quality webcam, mic, and screen shares.

·       Enhance Performance: Continually optimize application bundle sizes, state management, and DOM rendering to handle thousands of concurrent live events
What We’re Looking For
Core Frontend Expertise

·       React Mastery: 4+ years of professional experience building complex, production-grade applications with React, modern state management (Redux, Zustand, Context API), and TypeScript.

·       Responsive Styling: Deep understanding of CSS-in-JS (Styled Components, Emotion) or utility-first CSS frameworks (Tailwind) to build fluid, responsive layouts.

·       Clean Architecture: Experience with component-driven development, custom hooks, and implementing robust frontend testing suites (Jest, React Testing Library).

Streaming & Media Experience (Highly Preferred)

·       Video Delivery Protocols: Strong familiarity with live video protocols like HLS, MPEG-DASH, or ultra-low-latency WebRTC.

·       Browser Media APIs: Hands-on experience working directly with the HTML5  tag, Media Source Extensions (MSE), and navigator.mediaDevices .

·       Player Customization: Proven experience embedding and customizing open-source media players (Video.js, Hls.js, Shaka, etc.).

·       Real-time Event Handling: Strong background working with asynchronous data streams and real-time networking protocols like WebSockets.

Bonus Points If You Have

·       Experience building streaming analytics dashboards to track video Quality of Service (QoS) metrics like startup time and bitrates.

·       Familiarity with cloud-based video ingestion and transcoding workflows (AWS Elemental, Mux, or Livepeer).

·       A passion for UI/UX design and a sharp eye for smooth animations (Framer Motion).
