Senior Backend Engineer Golang/Python/NodeJS

CDN Optimization & Routing

Build dynamic routing services across in- house & third- party CDNs (BytePlus, Gcore, etc.) based on real- time conditions (ISP, bandwidth, cost, QoS).
Implement feedback loops using QoE metrics for automatic CDN selection.

Experimentation & Config Platform

Develop APIs/services for real- time A/B testing, feature flagging, and config- based behavior without redeployments.
Collaborate with data engineers to design pipelines and stores for variant analysis.

Engagement Platform

Integrate with messaging providers and build routing/logging systems for reliability.
Design backend systems for omnichannel messaging (push, in- app, email) using real- time user segmentation.

Transcoding System Integration

Ensure role- based access, audit logging, and fail- safe designs.
Build control panels for configuring backend services, transcoding profiles, and routing rules.

Core Engineering Practices

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 when required.
