About opportunityAbout opportunity

MoEngage Inc. is a technology company based out of Bangalore and San Francisco. We are focused on solving the problem of retention and engagement in mobile apps and websites. We built a User Analytics and Engagement platform to help app companies understand user behaviour in real time and deliver personalised interactions (big data personalisation at scale). We work with most of the top consumer-internet companies in India across E-commerce, Travel, Food, etc. We are a fast-growing team of young people, who worked earlier at mobile and startup companies. We have seen a considerable growth since the inception of the company, to give a sense of scale we deal with, imagine receiving 5 billion interactions in a month from major e-commerce, travel and food companies together on a global scale. Maintaining the infrastructure on such a scale is a huge challenge. We face interesting and exciting challenges on a daily basis, ingesting high rate of data from users (more than 2.5k per second) means things like scalability, availability and efficiency are hugely important.
