Overview

At Liftoff, we’re solving one of the core problems faced by every mobile app: growth. To do so, we build Machine Learning models and infrastructure that can accurately predict which apps a user will like and how to connect them in a compelling way. Our systems operate at a scale unseen outside of the largest Internet companies — processing over half a million requests per second and interacting with over a billion users. Our technology is creative and we have strong product-market fit; as a result, we’ve already reached profitability and are seeing tremendous growth.

As a Machine Learning Engineer at Liftoff, you will:

Own both the ML models and the underlying software tooling and infrastructure. Our ML Engineer role combines the classic “ML Scientist” and “Data Engineer” role at other companies.
Have a closed feedback loop from hypothesis generation to live AB testing, with no cross-team friction and sub-day iteration cycles.
Take on unique modeling challenges not covered in the scientific literature, like extreme positive sample sparsity and labelling delay.
Work with modeling techniques at the state-of-the-art of probability prediction, as well as a multitude of other ML areas from NLP to CNNs.
Become an expert in Clojure, Go, and the many other cutting-edge open source technologies that maximize our development velocity.
Join a nimble, consistently excellent, and experienced engineering team (former Google/LI/Ooyala/etc).
