Who are they?

BlaBlaCar is the world’s leading long-distance carpooling platform – a global, trusted community of 100 million members in 22 countries. BlaBlaCar is creating an entirely new, people-powered, travel network that connects people looking to travel long distances with drivers heading the same way, so they can travel together and share the cost. With the recent integration of a coach bus network, and a commuter service for short-distance carpooling, BlaBlaCar aims to become the go-to marketplace for shared mobility.

With a dedicated member relations service, a state of the art web and mobile platform, novel insurance solutions and a fast-growing community, BlaBlaCar is making travel social, cost-effective and practical for millions of members. BlaBlaCar is continuously innovating, developing smart-stop and smart-pricing algorithms that dynamically unlock millions of possible local meeting points and, in effect, turn every highway into a major transport line while also allowing for more granular point-to-point service in less accessible areas. By doubling the number of people in cars (from 1,9 to 3,9 people), BlaBlaCar saved 1.6 million tonnes of CO2 in 2018 (the equivalent of traffic in Paris for a year).

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.

The context :

By joining our Foundations department, you will be working alongside talented individuals grouped in small agile teams that each have strong ownership of their stack and goals.

Our foundations are composed of six subteams that “provide consistent, easy to use, secured infrastructures, services, and expertise to support BlaBlaCar’s growth and evolution”.

The Security Team has three main objectives:

- Reduce BlaBlaCar risk exposure by defining and implementing a strategy to identify, report, and tackle the most critical risks

- Implement a shift-left strategy and autonomy within the teams via training, guidelines, and tooling

- Detect, investigate and respond to security incidents

Role description:

As a Senior Security Engineer, your core mission will be to ensure that the Security team has the proper tools, training, and processes to monitor, investigate and respond to threats.

We expect you to lead BlaBlaCar's security operations by organizing the team security run and participating in run activities. You will be in charge of expanding our SIEM detection and incident response capabilities. You will also increase our security coverage by integrating new security tools.


1. Organise and lead the Security team run:

  • 3. Integrate and deploy additional security tooling:

  • Snyk (dependency vulnerability scanning)

  • Investigate SIEM alerts on Splunk (5 alerts/day on average):
  • Virus / Malware (EDR on employees' laptops - Phishing on company email)
  • Authentication (Impossible travel/brute force/failed authentication)
  • Cloud Security (Prisma Cloud (PAN) alerts on potentially dangerous configuration for AWS and GCP)
  • Google Workspace activity (data exfiltration/privilege escalation)
  • Lead and coordinate basic incident response for low to medium-level security incidents following established procedures (less than one a month on average)
  • Your Qualifications:

  • Familiar with Cloud environment and with GitOps (infra as code, GitHub, CI/CD, …)
  • Working proficiency in English and French
  • Good communication skills: you are able to explain complex security subjects to non-technical collaborators
  • If you don’t meet 100% of the qualifications outlined above, tell us why you’d still be a great fit for this role in your application!
