Software Engineer Backend - BlaBlaCar Daily

  • Paris, France
  • Employees can work remotely
  • Full-time

Company Description

BlaBlaCar’s vision is to bring fairness, freedom and fraternity to the world of travel. 

BlaBlaCar was created in 2006 with one dream in mind: fill the millions of empty seats on the road to create an efficient, affordable and friendly way to travel. Today, our global, trusted community counts 90 million members in 22 countries, enabling a smarter, large scale and truly sustainable transport network. 

Born from a simple idea of people sharing their rides, BlaBlaCar’s ambition is to become the go-to marketplace for shared road mobility. We offer a long-distance carpooling service, a commuting carpooling service, and a long-distance bus service. A filled bus emits one third of the emissions per passenger kilometer as an average car -- so we want to fill those seats too! 

In 2019, 100 million travelers used BlaBlaCar globally, saving 1.6 million tons of CO2. Meanwhile, we enabled human connections, bringing people closer together in more ways than one, with 87% of members believing carpooling to be an enriching experience. 

BlaBlaCar offers a unique international environment with a team counting 40 nationalities, serving a global member-base from 7 offices in Berlin, Kyiv, Madrid, Milan, Moscow, Paris (HQ), São Paulo and Warsaw. English is the official spoken language across BlaBlaCar. We are privately-held and founder-led. Our team of 500 employees is entrepreneurial, passionate and fundamentally mission-driven.
