Our goal as a team is to provide the necessary tools, technological infrastructure, and systems to support our advertising and creative teams, to increase effectiveness throughout the publishing pillar of WeTransfer and deliver on a promise of growth for WeTransfer. WeTransfer’s Ads Platform focuses on delivering new, innovative products to take our publishing arm to the next level.

Does this mission resonate with you? We're looking for a talented Senior Fullstack Engineer with an architectural mindset, awesome problem-solving abilities, a proven track record of navigating complex software development landscapes, and strong programming skills.
Our Stack
Here’s some background on what you could be working with, aka our Ad Platform stack: AdSDK, backend proxy, and ad server. Ad requests are initiated by the AdSDK which are processed and enriched by our backend proxy, which is then directed to our ad server, which houses our campaigns. The ad server retrieves the most suitable ad, sends it back to the AdSDK via the proxy, and ensures the right ad reaches the end user. Simultaneously, we maintain stringent tracking of all ad events for measuring campaign performance and continual optimisation. We use a monorepo (NX), developed with Node.js using NestJS in TypeScript.
