Programmatic traders are the behind-the-scenes experts that make the whole world of digital advertising work. Pretty much all the adverts shown online are bought and sold in auctions – a bit like a stock market, but with more creativity and less likely to crash the global economy.

A programmatic trader’s job is to understand these auctions, so they connect everyday internet users with the brands, content, and causes they care about by using insights to show the right adverts to the right people (and not to annoy people who aren’t interested).
