Senior Front End SDE (React.js) for Marketing solution for world leading game company (only Europe)

We’re building a complex marketing solution for Blizzard, the legendary game company from California.
The product is based on the concept of native advertising. The key idea is to allow advertisers to embed personalized advertising content right inside the game’s virtual space. For example, players will see the Nike ads just on the wall of the building they pass through when driving a car in a race simulator.
The platform will collect players data, segment the audience, predict user behavior and optimize marketing campaigns.
The project is full of exciting challenges related to big data and high-load. Technology is developed from ground zero, with no legacy, modern stacks only.
