BlaBlaCar is the world’s leading carpooling platform, created with one dream in mind: leveraging technology to fill the millions of empty seats on the road. We offer long- and short-distance carpooling as well as a bus marketplace, with the mission to become the go-to marketplace for shared road mobility.

Today, our community counts over 90 million travellers in 22 countries, creating a smarter, friendlier and carbon-saving transport network. Every year, our community saves 1.6 million tons of CO2e by sharing the road, equivalent to the CO2 emissions generated by Paris traffic in a year. But it doesn’t stop here – our team of 250+ engineers is developing innovative algorithms to further unlock the potential of shared travel and multiply its impact.

We’re looking for people to join our journey – people who care, who are driven by impact and innovation, and who want to thrive in a fast-paced entrepreneurial environment. We offer a flexible workplace where we count on each other to take initiative. So join the ride – we can’t wait to see where it takes you.

We are looking for a Senior Data Scientist to join the Data Science Marketplace team, whose mission is to improve the efficiency of the carpool marketplace. We aim to ensure that the passengers find a car that suits their needs and the driver has passengers to share their travel cost.

One of BlaBlaCar’s key strategic goals is to leverage data through Machine Learning in order to trigger growth opportunities. Data science has been instrumental to successfully launching new services for the past two years, yet the potential for improvements is still massive. If you are looking for exciting challenges, impacting millions of users and working on a state-of-the-art cloud platform, come and join us!

Among many projects, the team delivers Machine Learning driven tools to optimize the prices of the trips on the platform. BlaBlaCar data stack is composed of the Google Cloud Platform suite (BigQuery, Pub/Sub, GKE, Cloud Run, ...).

Data scientists collaborate closely with ML engineers, data analysts and product managers to deliver end-to-end ML projects from data exploration to production.
