You'll drive company-wide backend initiatives spanning transactions, search, monetization, permissions, and integrations. ➡️ What you'll do Anticipate and solve scale challenges before they hit: You'll map technical risks across Foundations' core systems — ~600k daily transactions approaching 1B total, search indexing, billing — and drive the architectural work that keeps Qonto's growth ahead of its infrastructure. Lead broad, high-stakes technical initiatives: You'll own end-to-end programs spanning multiple teams, touching Legal, Risk, Compliance, and leadership, with real business consequences. Shape the platform's future: You'll identify where Foundations needs to invest next — from granular permissions to AI-native integrations — and translate those bets into technical roadmaps. Multiply the engineering org around you: You'll raise the bar for groups of engineers through mentoring, coaching programs, and technical enablement — not just one-on-ones. Bridge business goals and backend decisions: You'll connect company and customer needs to concrete technical plans and communicate them clearly to engineers and executives alike. ➡️ What we're looking for Large-scale backend architecture: You've designed and scaled high-volume systems — transactions, search/indexing, billing, or similar — under real growth pressure. Company-wide technical leadership: You've driven complex, multi-team initiatives that touched Legal, Risk, Compliance, and leadership, and you can tie every technical decision to a business outcome. Autonomous by default: You thrive in ambiguous environments, map ecosystems yourself, surface risks early, and propose initiatives without waiting for direction. Multiplier, not just contributor: You've raised the bar for groups of engineers through mentoring programs, documentation, or structured technical enablement. AI in your workflow: You use AI tools to accelerate how you architect, prototype, and communicate — and you're excited about what AI-native integrations could unlock for a platform like ours. ➡️ What we can offer you Scale Qonto's next chapter: Usage and data volumes are growing fast — you'll architect solutions before systems become bottlenecks, not after. The largest engineering domain at Qonto: Foundations spans ~110 backend engineers across internal tooling, monetization, integrations, transactions, permissions, and automation — it's genuinely Principal-scale scope. Complex, urgent, business-critical challenges: From search indexing trade-offs at 1B+ interactions to AI-native integrations, the technical problems here directly shape the product millions of customers use daily. Real ownership over technical direction: You'll identify what matters, propose the roadmap, and drive execution — with the autonomy to shape the domain's future. Don't check every box? If you're excited by the scope and feel strongly about the mission, we'd love to hear from you anyway.

You'll combine Generative AI with proven machine-learning techniques to create products with measurable impact — adoption, faster task completion, user satisfaction — while ensuring reliability, privacy, and continuous monitoring in production. ➡️ What you'll do Develop ML models end-to-end: From understanding product requirements to training, evaluating, and deploying models in production. You design, iterate, and ship — not just prototype. Integrate ML into the product ecosystem: Align with Product Managers, Data Engineers, and Backend Engineers to ensure your models are seamlessly embedded in Qonto's financial services. Build the ML Ops framework: Create the infrastructure for the team to scale — model drift detection, performance tracking, automated retraining pipelines, monitoring, and alerts. Put models into production with rigour: Robust technical implementation, quality assurance, and continuous monitoring. Client-facing AI in financial services has no room for silent failures. Raise the bar for the team: Share best practices, contribute to internal tooling improvements, and mentor peers across the ML team. ➡️ What we're looking for 6+ years as an ML Engineer with ML Ops experience: You've developed and deployed client-facing ML products end-to-end — not internal tools or dashboards. You can show measurable impact on real users. Modelling expertise: Experience building and optimising machine learning models for external customers. You know when to use GenAI and when proven ML techniques are the better choice. Strong Python engineering: You write resilient, testable code at scale. Proficient with FastAPI (or similar), third-party service integration, and database interaction in production. ML Ops fluency: Familiar with tools that automate model retraining, performance checking, and drift detection. You've built or significantly improved ML infrastructure before. Fluent in English: Qonto's working language. ➡️ What we can offer you Customer-facing AI with real impact: Your models will be used directly by hundreds of thousands of business customers. You'll see adoption metrics, not just offline evaluations. A modern, flexible stack: Python, Snowflake, Kafka, Kibana, PostgreSQL, Airflow, AWS, Prometheus, ArgoCD, GitHub, Cursor. You have the freedom to test any tool as long as it helps reach the target. A team building AI at the core of fintech: 10 AI Engineers and 3 Data Ops working on innovative solutions at the heart of Qonto's financial services — not a side project. Clear IC growth track: Individual contributor career path for those who want to become deep experts in their field, with access to the latest AI technologies. ➡️ Your future manager Option A Your manager will be Marianne Borzic Ducournau, Head of Data Products. Her background? A graduate of École Polytechnique, Marianne went on to lead Data Science teams at Uber and Amazon in San Francisco before joining Qonto four years ago to build our Data Science team from scratch — hiring the founding members and defining the technical direction. What does she bring to the team? A rare combination of applied ML expertise and business context from Finance — she helps people see both the technical and the strategic side of what they're building. Option B Your manager will be Benjamin Wolter, Head of AI Products. His background? After earning his PhD in Physics and leading ML Engineering and Data Science teams across last-mile logistics and digital marketing, Benjamin joined Qonto to lead our AI Products team. What does he bring to the team? Deep technical ML expertise, practical experience building scalable ML systems, and a management style built around ownership and autonomy — he creates the conditions for people to grow without hand-holding.

You'll drive the maturity and scalability of our ML/AI capabilities, addressing concrete business problems while fostering innovation. ➡️ What you'll do Own the ML product roadmap end-to-end: Define what we build, why, and in what order — gathering insights from engineering, data science, and business teams to develop a prioritized strategy that addresses real customer needs. Drive key ML product initiatives: Lead the definition and design of ML solutions for products like Attachment Matcher, Transaction Categorizer — from discovery through delivery. Collaborate across the full stack: Work with data scientists, engineers, and business stakeholders to ensure successful implementation of ML capabilities that drive measurable business value. Own your decisions and communicate them clearly: Articulate the rationale behind priorities and engage key stakeholders — including customers, product, and executive teams. Continuously improve through data: Monitor and analyze the performance of models and products, making data-driven recommendations to raise the bar. ➡️ What we're looking for Product management experience with an ML focus: You have proven experience in product management, with concrete examples of ML products you significantly scaled. You think in outcomes, not features. Technical fluency in ML: You have a solid grasp of machine learning concepts and applications, allowing you to collaborate effectively with technical teams and translate complex ideas into product requirements.
