PROJECT
You will join the team working on Vast Gateway, a high-throughput edge proxy built on Cloudflare Workers and responsible for handling tens of millions of requests per day within the video advertising delivery flow.
The platform retrieves and processes VAST responses, applies modifications including malicious ad protection logic for VPAID creatives, and consolidates multiple VAST documents into a single XML response for video players. Since all advertising traffic flows through the gateway, the system is designed with a strong focus on low latency, high availability, scalability, and operational stability.
