Junior Full Stack Developer

We make digital ads. That includes the banners you see on the sides of websites, social media ads, YouTube ads, and more. We specialise in personalised ads (showing different ads to different people). That means we need tools to automate the production and deployment of hundreds of variations of our ads. In the most complex cases, we generate and deploy these ads on the fly using live data, such as weather data or price data. That’s where you come in.
