Your Mission
We are looking for a Senior Software Engineer to join our Developer Experience team at BlaBlaCar.

As part of the bigger Foundations team, you’ll join a large group of talented individuals on a mission to provide consistent, easy to use, secured infrastructure, services, and expertise to support BlaBlaCar’s growth and evolution by catering to the needs of our fellow developers.

The Developer Experience team's mission is to remove the friction other engineers may experience when developing and maintaining services, allowing them to focus on delivering business value. As a member of the team, you will develop and document libraries and tools that streamline the development process, and also provide technical support to all BlaBlaCar’s backend teams.

You will report to Ceydric, Engineering Manager of the Developer Experience team and work within a team of 4 engineers. You will collaborate with BlaBlaCar’s backend teams to understand their needs and pain points, and work with them to implement solutions that improve the development process.

For this position, you should have strong communication and collaboration skills, be comfortable walking others through solutions and approaching solutions from a user perspective.

Your Responsibilities
• Create maintainable libraries that address cross-cutting concerns for our backend development teams
• Understand how other engineers work and use their tools
• Support backend teams during decision making and problem solving phases
• Document and explain the solutions we build as a team
• Liaise with both backend and ops teams
• Conduct technical migrations from start to completion

Your qualifications
• You have a solid knowledge of the Java language and ecosystem, and have good foundations in software architecture
• You like knowing how things work under the hood, and are not afraid to look for answers all the way to the source code
• Ideally, you have distributed and maintained libraries or tools, either at work or as open source projects
• You are not afraid to ask questions, and to proactively seek (external) feedback
• You value intuitive and straightforward end user experience when designing software
• You feel comfortable making technical choices, and balancing organizational efficiency and company culture with other constraints
• You are fluent in English

Our technical environment
• Service Oriented Architecture, with over 100 backend services in Java, leveraging Spring Boot
• Inter-service communication using OpenAPI and Kafka
• GCP hosted Kubernetes infrastructure and DevOps stack managed with GitOps practices
