Kayzen

Kayzen builds programmatic advertising technology designed to give marketers ownership of their media buying, full transparency into campaigns and direct control over their data. The company's media buying platform operates at high-throughput, low-latency scale: it handles 2 million requests per second at sub-millisecond latency and manages petabytes of data.

The engineering work spans distributed systems, real-time bidding and high-throughput systems, big-data management at petabyte scale and low-latency systems engineering, applied to ad-tech platform problems where bidding decisions must be made within tight real-time constraints.

Kayzen employs more than 70 people, referred to internally as Kayzenians, across more than 10 locations worldwide, including Berlin and Bangalore. The team represents more than 20 nationalities and works in a distributed arrangement spanning time zones. Stated cultural principles include curiosity, collaboration and continuous learning, with an emphasis on internal transparency, experimentation, investment in individual growth and diverse perspectives.
