Platform Engineering (Golang)

CDN Optimization & Routing Logic Build services to dynamically route traffic across in-house and third-party CDNs (e.g., BytePlus, Gcore) based on real-time conditions (ISP, bandwidth, cost, QoS). Implement feedback loops using QoE metrics to adjust CDN selection automatically. Experience Platform Develop APIs and services that support real-time A/B testing, feature flagging, and config-based behavior without code redeployments. Work with data engineers to design pipelines and stores for experimentation data and variant analysis. Engagement Platform Design backend systems to orchestrate omnichannel messaging (push, in-app, email) using real-time user segmentation and behavioral triggers. Integrate with messaging providers and build routing/logging systems to ensure reliability. Transcode System Integration Build UI control panels for configuring backend services, transcoding profiles, routing rules, and more. Ensure role-based access, audit logging, and fail-safe designs for sensitive operations. Core Engineering Principles Design clean APIs, asynchronous workers, and scalable microservices with observability (metrics/logs/traces). Write automated tests (unit/integration/load), CI pipelines, and infrastructure-as-code if needed.
