Lead ML Scientist
The Lead ML Scientist will be responsible for implementing success metrics, driving experimentation, and presenting impacts to stakeholders. This role involves developing and evaluating predictive models using various mathematical methods and designing large-scale ML systems with advanced frameworks like TensorFlow/Keras/PyTorch, while also managing a team of data scientists and ensuring cross-team alignment.
Technology is at the core of everything we do. Our technology team helps us deliver a mobile-first experience across platforms (Android & iOS) while managing over 300 million rpm (requests per minute) at peak with a user concurrency of 10 million.
We have over 150 micro-services written in Java and backed by a Vert.x framework. These work with isolated product features with discrete architectures to cater to the respective use cases.
We work with terabytes of data, the infrastructure for which is built on top of Kafka, Redshift, Spark, Druid, etc. and it powers a number of use cases like Machine Learning and Predictive Analytics. Our tech stack is hosted on AWS, with distributed systems like Cassandra, Aerospike, Akka, Voltdb, Ignite, etc.
