Lead Engineer - Real-Time Video Infrastructure

Stream powers real-time Chat, Video, Activity Feeds, and AI Moderation for billions of end-users across thousands of apps - from Strava and Bumble to eBay and Patreon. Our infrastructure processes millions of concurrent connections daily, and our developer-first SDKs let teams ship production-grade video calling and livestreaming in hours, not months.

• Architect and evolve our Go/Pion-based SFU handling real-time video and audio traffic at global scale
• Build and improve our media pipeline supporting WHIP, WHEP, RTMP, SRT, HLS, and SVC codecs
• Work on bandwidth estimation, codec optimization (Opus, VP8/VP9/AV1), and low-latency delivery
• Expand our AI integrations for real-time audio and video processing
• Improve the stability, performance, and feature-set of our edge server network
• Collaborate directly with customers on advanced integration challenges
• Lead a small team: 1:1s, performance reviews, code reviews, and technical roadmap Core technologies: Go, WebRTC, RTMP, SRT, HLS, Protobuf, SVC codecs, Opus, CockroachDB/Postgres, RocksDB, Raft, Redis
