The design of such things like security, storing data, caching and load balancing will be put completely on you.

The target part of the product is data analysis engine, our core service built with Scala, Akka, Kafka, Spark and Cassandra. And currently we are looking for a person who will work on development of our recommendation system.

О проекте

Everything in Lotusflare is about mobile traffic. The core team was detached from mobile infrastructure department of Facebook. Our customers are world biggest consumers of mobile traffic (Skype, Facebook, LinkedIn) and cellphone operators (Telenor, Sprint, Verizon). The core mission of the company is to build middleware products that make mobile internet traffic more accessible and affordable.

We care about people in developing countries, And we keep in mind that the half of population of Earth still do not have permanent internet access, and thus appear to be the greatest emerging market with boundless growth potential.

We are proud to be the company that was backed by Google Ventures, Macquarie Capital, Compound, Social Capital and lots Silicon Valley angels.
