Machine Learning Engineer
At Liftoff+Vungle, we're solving one of the core problems faced by every mobile app: growth. To do so, we build Machine Learning and Big Data-driven technology that can accurately predict which apps a user will like, and connect them in a compelling way. Our systems operate at a scale unseen outside of the largest Internet companies -- processing over 4 million requests per second and interacting with over a billion users a week. Our technology is innovative and we have strong product-market fit; as a result, we're profitable and seeing tremendous growth. Across our engineering teams, we offer a wide range of opportunities for different skill levels and experiences.
As a Machine Learning Engineer at Liftoff+Vungle, 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).
Location:
This role is eligible to work out of any of our below North America office locations or is eligible for full-time remote work in one of our entities.

Desired qualities and experiences:
- Very strong coding ability (experience in Go and Clojure is a plus).
- 3+ years of industry experience applying Machine Learning to large scale problems.
- Strong core CS fundamentals (data structures, algorithms, architecting systems).
- A passion for quality and excellence, and the ability to temper it when necessary to ship.
- Sets ego aside in pursuit of finding the best solution, no matter where it comes from.
- Self-motivated and a great ability to hustle.
- B.S. or higher in Computer Science. PhD a big plus.
