About the Team

At Leanplum, we want to make marketing more relevant and personalized. In order to do that, the Data Platform team needs to process huge amounts of data and resolve that data into users and groups of users. This work is foundational to our entire product. Our team manages distributed, high volume APIs and data ingestion services through which we currently serving over 25k low latency requests per second, processing over 16B events a day, for billions of users, and growing fast. We will work with partners in geolocation, machine-learning, in-store analytics, and more to ingest all relevant types of data. Every data point about users, whether it is from our SDKs, servers, or third parties is processed, enriched and managed by the team. We then use those data points to group users in innovative and intelligent ways. Most importantly, we are responsible for the compliance, control, and security of this data. Our distributed Java services and caches run on Google Cloud, while our SDKs are embedded in billions of devices over the world.
