Mission Design, operate, and harden the live AV pipeline (ingest → transport → packaging → CDN delivery) across multiple clouds and regions.
Multi-cloud DevOps / 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 (GitHub Actions), observability (CloudWatch, structured logs, tracing).
CDN experience: configuring and debugging at least one major CDN (CloudFront, 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/FairPlay/PlayReady) at a high level, WebRTC/TURN basics.
Security mindset: source authentication, credential rotation, IAM scoping (across AWS and Tencent), secrets handling, DRM key protection.
