Your Mission

By joining our Foundations department, you will be working alongside talented individuals grouped in small agile teams that each have strong ownership on their piece of these goals. Foundations is composed of seven teams which “provide consistent, easy to use, infrastructures, services, and expertise to support BlaBlaCar’s growth and evolution”.

The Site Reliability Engineering team (SRE) is responsible for providing best-in-class Observability, Alerting, and Incident management tools and processes to service teams. As an enabling team, we help BlaBlaCar engineers to efficiently improve their service reliability. Empowering developers and bringing them our reliability expertise are at the core of our daily work.

Technical Stack:

• Core Infrastructure: Kubernetes, Google Cloud Platform
• GitOps/Delivery: GitHub, Terraform, Flux, Helm, Jenkins
