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.

• Graduated from college or higher in IT, Software Engineering, Computer Science, or a related field
• 3+ years of experience in backend engineering, preferably in platform, infrastructure, or media-heavy domains.
• Strong understanding of distributed systems, microservices, and event-driven architecture.
• Experience with real-time data processing and building APIs that drive dynamic behaviors.
• Familiarity with CDN technologies, transcoding pipelines, or A/B testing platforms is a plus.
• Bonus: Experience with internal platform or developer tools.
