What Video Engineers Actually Build
Video engineering spans from encoding to playback.
Encoding and Processing
Preparing video for delivery:
- Transcoding — Converting between formats and resolutions
- Codec optimization — H.264, H.265/HEVC, VP9, AV1
- Adaptive bitrate encoding — Multiple quality levels
- HDR processing — High dynamic range content
- Audio encoding — AAC, Opus, Dolby
Streaming Infrastructure
Delivering video to users:
- Live streaming — Real-time video delivery
- VOD delivery — On-demand content
- CDN integration — Global content distribution
- Protocol implementation — HLS, DASH, WebRTC
- DRM — Content protection
Player Development
Client-side video:
- Video players — Web, mobile, TV players
- Adaptive streaming — Quality selection logic
- Buffering optimization — Smooth playback
- Analytics — Quality of experience metrics
- Low-latency playback — Near-real-time delivery

Common Hiring Mistakes
Hiring Generic Backend Engineers
Video has specialized requirements: codecs, streaming protocols, quality metrics. Generic engineers need significant ramp-up. Prioritize video or media experience.
Ignoring Quality Understanding
Video is about perceptual quality, not just pixels. Engineers who don't understand quality metrics (VMAF, SSIM) can't optimize effectively.
Underestimating Real-Time Challenges
Live streaming and video conferencing require real-time processing. Batch-processing experience doesn't transfer directly. Look for latency-sensitive experience.
Missing Platform Knowledge
Video players differ across platforms (web, iOS, Android, TV). Platform-specific expertise accelerates development.
Where to Find Video Engineers
High-Signal Sources
Video engineers typically come from streaming companies, video conferencing platforms, or broadcast technology. Netflix, YouTube, Twitch, and Zoom alumni have deep video expertise. Look for engineers at video infrastructure companies like Mux, Cloudflare Stream, or AWS Elemental. Broadcast technology companies (traditional media transitioning to streaming) also produce strong candidates.
Conference and Community
Demuxed is THE conference for video engineers—speakers and attendees are excellent candidates. NAB (National Association of Broadcasters) Show attracts streaming technology professionals. The Video Dev community and streaming protocol mailing lists surface practitioners.
Company Backgrounds That Translate
- Streaming giants: Netflix, YouTube, Disney+, HBO Max—large video teams
- Live streaming: Twitch, YouTube Live, TikTok Live—real-time challenges
- Video conferencing: Zoom, Google Meet, Microsoft Teams—low-latency expertise
- Video infrastructure: Mux, Cloudflare, AWS Elemental, Brightcove—platform experience
- Short-form: TikTok, Instagram Reels, YouTube Shorts—mobile video expertise
- Broadcast: Traditional media companies moving to streaming
Open Source Involvement
FFmpeg contributors, VLC developers, and open-source player (video.js, hls.js) maintainers indicate deep video expertise.
