ABOUT THE TEAM 

Our team sits at the nexus between the flagship Basis Platform application and our Demand-Side Platform, a real-time auction engine that competes in billions of ad auctions a day, each with a sub-100ms latency. 

We implement features and workflows that surface the DSP capabilities making the functionality approachable for the novice and power users alike. The work is high-visibility, revenue-impacting, and customer-facing. The features and projects we take on reach across internal and external boundaries, services, and orgs. We deal in data, and lots of it! Implementation is not just code and structure, we consider resources, performance, and scalability.
