Role summary

Lyft is seeking Masters or PhD students for a Data Science Intern position focusing on Algorithms for Summer 2027. This role involves building mathematical models for core platform services, tackling diverse problems in optimization, prediction, modeling, inference, transportation, and mapping. Interns will partner with cross-functional teams, perform data analysis, write production modeling code, and design/analyze experiments. The ideal candidate has experience coding in Python or SQL/R, standard data science libraries, and ML tools, with expertise in optimization, machine learning, or probabilistic/statistical modeling. A background in a relevant mathematical or scientific field is required, with a graduation date between December 2027 and June 2028. This is a hybrid role based in Toronto.

At Lyft, our purpose is to serve and connect. We aim to achieve this by cultivating a work environment where all team members belong and have the opportunity to thrive.

Lyft’s Data Science Team builds mathematical models underpinning the platform’s core services. Compared to other technology companies of a similar size, the set of problems that we tackle is incredibly diverse. They cut across optimization, prediction, modeling, inference, transportation, and mapping. We're looking for Masters or PhD students who are passionate about solving mathematical problems with data and are excited about working in a fast-paced, innovative and collegial environment.

We are hiring for a variety of Data Science interns, focusing on the following specialties:

Optimization: Construct and fit statistical or optimization models that facilitate automated decision making in the app.

Machine Learning: Design, build, tune, and deploy machine learning models with a special emphasis on feature engineering and deployment.

Inference: Design and analyze tests in our dynamic marketplace, estimating statistical and ML models to enable better decisions, and developing and evaluating algorithmic policies in our pricing, dispatch, and incentives systems.

You will report into a Science Manager.
