Job Description

RTB is high load bidding engine handling up to 200K requests/s, working close to real-time with a time box of 100 ms to handle one request (including transportation). We work with a wide range of technologies in this team, Cassandra, Aerospike, .NET, MS SQL, JavaScript, Puppet – to name a few.

It’s a platform where ad inventory is bought and sold on a per-impression basis, via programmatic instantaneous auction, similar to financial markets. With real-time bidding, advertising buyers bid on an impression and, if the bid is won, the buyer’s ad is instantly displayed on the publisher’s site. Real time bidding lets advertisers manage and optimize ads from multiple ad-networks by granting the user access to a multitude of different networks, allowing them to create and launch advertising campaigns, prioritize networks and allocate backfill percentages.
