• Connect client player interfaces with adaptive bitrate algorithms (ABR) and DRM licensing infrastructure.
• Instrument client telemetry to measure user engagement, bitrate transitions, and network dropped frames.
• Debug critical production playback issues and adhere to strict web security standards (CORS, CSP, XSS prevention).

✅ What You'll Need

• 2–4 years of hands-on professional web engineering experience with React, Next.js, and TypeScript.
• Direct production experience with HTML5 video engines (Shaka Player, HLS.js, Video.js, or Dash.js).
• Solid knowledge of adaptive video protocols (HLS and MPEG-DASH) and video manifest parsing.
