Your Mission
We are looking for a Senior Backend Engineer to join the Payment Squad. They manage BlaBlaCar’s payment solutions that provide reliability, trust, and a smooth end-to-end experience.
As a Senior Backend Engineer, your role will be to drive the delivery of a reliable and scalable platform that supports the full payment lifecycle, fraud fight, and compliance requirements. You will take ownership of complex, cross-functional projects—such as finalizing the implementation of our payment orchestrator—and play a key role in expanding BlaBlaCar's business by proposing and integrating tailored payment methods for our various operational countries.
You will act as a technical reference, demonstrating strong autonomy, deep architectural thinking, and the ability to synchronize with multiple external teams (Legal, Cash Management & Finance, Payment Ops).
You will be reporting to the squad's Engineering Manager and working closely with a team of Software Engineers and a Product Manager.
Your responsibilities
Drive and deliver transverse and complex technical projects from design to deployment, demonstrating a deep understanding of technical constraints and implementation challenges.
Lead the finalization and scaling of the payment orchestrator and integrate new, adapted payment methods across different countries.
Take a step back to proactively propose platform improvements, task automation, and better observability (e.g., establishing SLO reviews with SREs and owning your monitoring and alerting stack).
Interact closely with various teams (Legal, Finance, Fraud/Payment Ops) to synchronize efforts, gather requirements, and assess cross-team impacts.
Act as a mentor and guide for mid-level (IC3) developers within the squad, elevating the team's overall engineering standards.
Participate in a cyclic on-call duty (approximately 1 week every 7 weeks) to ensure the high availability of our critical payment systems.
Your qualifications
You have 5 to 10 years of overall engineering experience.
You possess deep technical autonomy and a high level of critical thinking regarding software architecture and constraints.
You are fluent in Java and have advanced knowledge of frameworks such as Spring, or SpringBoot.
You have hands-on experience with service-oriented architectures, Git, Docker, Kubernetes, and monitoring solutions (Datadog).
You have excellent, clear, and concise communication skills, allowing you to easily step into any workshop and share technical expertise with both technical and business stakeholders.
You are not reluctant to participate in on-call duties (mandatory for this role).
