AV Infra​/Streaming Platform Engineer

Mission

Design, operate, and harden the live AV pipeline (ingest → transport → packaging → CDN delivery) across multiple clouds and regions.

• Multi-cloud Dev Ops / SRE: hands-on with AWS and Tencent Cloud (or willingness to ramp on Tencent fast — APAC delivery matters). GCP a plus. Terraform, Kubernetes, CI/CD (Git Hub Actions), observability (Cloud Watch, structured logs, tracing).
• CDN experience: configuring and debugging at least one major CDN (Cloud Front, Tencent CDN/CSS, G-Core). Understands cache keys, signed URLs / token auth, origin shielding, purge strategies, multi-CDN failover.
• Backend: solid in Go and Python — Go for low-latency services and gRPC, Python for tooling, glue, probes.
• Networking fundamentals: UDP vs TCP, NAT/firewalls, TLS/mTLS, BGP/anycast at a conceptual level, packet-level debugging (tcpdump, Wireshark).
• Streaming concepts: RTP/SRT/RTMP ingest, HLS/DASH packaging, CDN delivery, latency tradeoffs, DRM (Widevine/Fair Play/Play Ready) at a high level, WebRTC/TURN basics.
• Security mindset: source authentication, credential rotation, IAM scoping (across AWS and Tencent), secrets handling, DRM key protection.

• China / APAC delivery experience (Tencent, Alibaba Cloud, ICP licensing realities).
• GStreamer / FFmpeg internals, transcoding pipelines.
• gRPC service design, protobuf schema evolution.
• Hands-on with SRT, WHIP/WHEP, Low-Latency HLS, MPEG-TS.
• Multi-CDN orchestration / steering (NPAW, Cedexis-style logic).
• Experience running 24/7 live services at scale.
