Serving the internal search engine to display results in the BlaBlaCar app & website

Managing the lifecycle of bookings (requested, accepted, confirmed...)

Providing key inventory information for all screens in the product requiring them.

• Enhance and maintain our critical geo-spatial services that handle:

Routing and Places: Computing routes using OSRM and Google Maps.

Dynamic Search: Powering features like Smart Stopovers via our meeting-points service.

User Location: Integrating GPS data to provide a seamless, real-time experience.

• Collaborate with the Product Manager and other engineers to refine requirements and translate business needs into robust technical solutions.

• Uphold and improve the team's code quality standards, providing detailed feedback and mentorship through code reviews.

• Document the solutions we build and ensure our APIs and services are well understood by consumer teams.

Your qualifications

• You have 3+ years of experience from companies with a strong engineering culture, within a growth context

• You have a solid knowledge of the Java language and ecosystem, and have good foundations in software architecture.

• You have hands-on experience with Git, Docker, Kubernetes, and monitoring solutions (Datadog)

• You have significant experience building, deploying, and operating backend microservices in a production environment.

• You value a product-oriented mindset and are focused on delivering business impact when designing software.

• You are not afraid to ask questions and to proactively seek feedback.

• You feel comfortable making technical choices and balancing business needs with technical constraints.

What we have to offer

• Full remote possible in the country of the role (+ access to BlaBlaCar co-working spaces in Bordeaux, Toulouse, Lyon, Nantes and Sophia Antipolis)

• 4 additional weeks parental leave 100% paid

• Financial support for home office equipment

• Employee Stock Ownership plan

• 25 days holiday per year + RTT
