learning, and highly scalable platform development. We build reliable, peta bytes scale

distributed systems using technologies such as Spark, Hadoop, Apache Flink, Airflow, Kafka, and

Druid. As part of Smaato, you will work on the applications where all threads come together:

Streaming, Processing, and Storage of the Ad exchange. Our ultra-efficient exchange processes more

than 125 billion ad requests daily, e.g. whopping 3.5 trillion in a month. Every line of code you

write matters as it is likely to be executed several billion times a day. We are one of the biggest

AWS users with a presence in four different regions.

Smaato’s data platform is a symphony of streams, orchestrations, microservices, schedulers,

analytics, and visualization technologies. The platform is supported by polyglot persistence using

Druid, DynamoDB, Vertica, MySQL, and a bunch of orchestration & streaming frameworks like

Airflow, Spark, Flink.

The job will involve constant feature development, performance tuning, and platform stability
