Principal Machine Learning Engineer

Lime is the world's largest shared electric vehicle company. We’re on a mission to build a future where transportation is shared, affordable and carbon-free. Our electric bikes and scooters have powered 400+ million rides in 250+ cities on 5 continents, replacing an estimated 100+ million car trips. Named a Time 100 Most Influential Company and Fast Company Brand That Matters, we achieved a fully profitable year in 2022, becoming the first in our industry to reach this milestone




Machine learning and AI play a central role in Lime’s future. We have just begun to scratch the surface of what’s possible when trying to solve Lime’s most complex challenges. Some of the problems we work on: what is the most effective way to deploy our scooters and bikes in each city to satisfy the most demand? How can cameras detect when someone rides a scooter on a pedestrian-only sidewalk in any city in the world? Can we predict when a vehicle will need repairs before it breaks? Lime’s Product ML Team is responsible for designing, building and deploying machine learning systems end-to-end. We both directly build some models as well as some underlying platforms for other teams to develop their own models
