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 travelers 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.
