AppNexus’ mission is to build a better Internet. We develop a technology platform that powers the real-time sale and purchase of digital advertising.

As a transparent and independent partner for some of the largest publishers and advertisers, AppNexus helps ensure that the Internet stays open and free.

As an Engineer on the Client Side Tech team, you will have the opportunity to quickly see the impact of your contributions to our clients and end users. Our team aims to solve problems that face online publishers on two main products: Prebid.js, and AppNexus Seller Tag (AST).

  • Scaling Open Source: Contribute to a growing open source project and leverage the community to continue scaling, while also increasing quality and bringing innovative features to market.
  • Prototype to Production: As an Engineer, you will work alongside Product Managers to go from iterating and validating a new concept with beta customers to developing it into production-quality code. Our challenge is to create new interfaces that are intuitive for first-time users and arm them with the capabilities they need to control the micro details of their businesses.
