About BlaBlaCar

BlaBlaCar is the world’s leading community-based travel network, connecting over 100 million members across 22 countries looking to carpool or travel by bus. By sharing rides and filling empty seats on the road, our community avoids 1.6 million tons of CO2 emissions every year (as if Paris was free of road traffic for a year!)

We are a global and diverse team of 700+ people with 45+ nationalities, and headquartered in Paris. We’re constantly looking for new ways to leverage technology to create a more affordable, convenient, flexible and sustainable way to travel. And we are always on the lookout for people who care about making a positive impact.


About BlaBlaCar Daily

We’re looking for people to join our journey on BlaBlaCar Daily.

We are an independent business unit of about 25 people who are passionate about building the best commute carpooling solution. We are actively developing and testing the product in France, Belgium and Switzerland with thousands of daily carpoolers.

You will join a small team of engineers operating independently of other products at BlaBlaCar and owning the software development of the product. This includes matching of driver and passengers, carpool features, payment processing, and geolocation tracking. The current project goal is to iterate quickly and take over the commuting carpooling market. Our team is composed of experienced people that have worked on successful services before. The job provides a lot of opportunities to learn and grow.

Your Mission

We are looking for a backend software engineer to join us on the development of BlaBlaCar Daily. You will work on technical challenges and product feature developments from the early conception meetings, development and test strategy, to deployment in production, on-call, observability, and support. You will mainly work on backend features with occasional contributions to our frontend projects.
