Lead SDK Game Developer

UP TO £95,000

ZEREN are delighted to have partnered with Bidstack, a global leader in in-game advertising based in London. They were founded in 2015, however, they are already post-IPO and have acquired over $45million in equity since going public in 2018.

Bidstack is a sell-side platform that puts SDKs into games before matching the seller with a buyer that opts to put the advert into the game real-time. The adverts themselves are designed to be immersed within the game and enhance the playing experience. They are the first platform of its kind to monetise live in-game advertising.

As a Lead SDK Game Developer, you will maintain and evolve their SDKs across multiple platforms ensuring they are compatible and functional to the gaming publishers. This is a crucial component of their product offering. You will have the opportunity to collaborate directly with gaming publishers to effectively integrate with their environments and improve the gaming experience for their customers.

They have an office in London and in Riga, Latvia. As well as collaborating externally with publishers, you will also work closely with the Engineering and Product teams to deliver collective solutions.

They are happy for you to be based anywhere in the UK, however, if based in London, they would love for you to join them in the office on occasion.
