You will act as the technical bridge between AI Product teams and Platform Engineering, playing a central role in Qonto’s strategy to integrate AI across business areas and improve customer experience for our 400,000+ clients. This position is open to full remote contract.

Your Future Manager will be Charles, Lead of the Data Platform team.

Charles is transitioning from an Individual Contributor role into a leadership position, after building strong expertise in data platform topics and architecture.

What does he bring to the team? Charles has a hands‑on, “architect‑embedded” leadership style: he stays close to the technical reality, helps unblock complex topics, and supports the team in making pragmatic architectural decisions. He values humility, collaboration, and clear communication, and fosters an environment where autonomy is encouraged and supported through impactful projects.

• Experience: 8+ years of experience in data engineering with demonstrated progression toward architectural roles, including deep expertise in designing and scaling data platforms.
• ML Lifecycle Mastery: Strong understanding of the full ML lifecycle: experimentation, training, deployment, monitoring, and retraining, with experience using modern ML platforms and tools (MLflow, Kubeflow, SageMaker, TensorBoard, or similar).
• Architectural Thinking: Proven ability to bridge technical and product perspectives, translating business needs into technical solutions, with a track record of making complex trade‑offs and driving technical consensus.
• Technical Leadership: Track record of influencing technical direction and mentoring engineering teams, with excellent communication skills to articulate technical vision to diverse stakeholders.
• Regulated Environment: Experience working in regulated environments (financial services preferred) is a plus, with a strong mindset for governance and compliance.
