Kafka streaming and Kubernetes are a plus. Our stack runs on AWS so a good knowledge of this platform is also a plus. * Coding Skills: You are an "AI-native" developer who embraces AI tools to write better, faster code. Hands-on experience with Python and Java/Scala is a plus. * Data Modeling: Experience with tabular data for classification problems and deep learning is a plus. * Feature Engineering: Solid understanding of how to transform raw data into high-quality features for machine learning. Experience building or maintaining feature stores. * Mindset: A "Product Owner" mentality for data, you don't just ship code; you own the reliability and scalability of the systems you build. * Communication: Fluent in English and the ability to articulate complex architectural choices to both technical and non-technical stakeholders. Notions of French can be a plus. Please note that, to comply with employment regulations, applicants are required to maintain residency and be legally authorized to work in the European Union in order to be considered for this position. ## Description We are looking for a Senior Data Engineer to take ownership of our ML Platform. You will help design, deploy, and evolve predictive models that power Adikteev's core adtech systems and you will be the architect of the infrastructure that enables our ML models to scale, perform, and deliver value at high velocity. You will join a high-performing team alongside Gwennaëlle, Nicolas, Pedro, and Alex. Our mission is to deliver efficient, scalable, and impactful machine learning systems - models that directly influence billions of real-time decisions per day. You will join a team that has full ownership of our ML ecosystem. As a Senior member, you won't just "execute" tasks. You will shape our technical DNA and take your share of the following challenges: * Architect, scale, and maintain our data infrastructure, ensuring it meets the rigorous demands of real-time and batch ML workflows. * Make sure data is always available: oversee processing, storage, aggregation, and API development. * Streamline our data processes by integrating efficient testing, monitoring, alerting, and error recovery. * Design and implement our feature store to centralize feature discovery, storage, and serving and build robust feature engineering pipelines. * Build and optimize highly scalable pipelines using Apache Airflow and Apache Spark, focusing on high reliability and cost-efficiency. * Contribute to innovation efforts, by exploring promising ideas from recent academic work and turning them into production-grade solutions. * Leverage AI coding tools (Copilot, Cursor, etc.) to accelerate development cycles and stay at the forefront of engineering productivity. * Drive best practices for data quality, CI/CD for data, and technical documentation. Mentor peers and identify infrastructure bottlenecks before they impact the business., * A 1h technical interview with a Senior Machine Learning Engineer and a member of our Data Engineering team, * A 1h team fit interview with Aldenis, VP Engineering, * A final interview with Cédric, Chief Technology Officer and Loïc, Chief Product Officer. If you require accommodations at any stage of the application process, please let us know. It will be handled confidentially by our HR and recruitment team. ## Related Videos - [Introduction to Azure Machine Learning](https://www.wearedevelopers.com/videos/368-introduction-to-azure-machine-learning) - [Understanding Kubernetes in a visual way](https://www.wearedevelopers.com/videos/100085-understanding-kubernetes-in-a-visual-way) - [API Design - Getting Started](https://www.wearedevelopers.com/videos/33-api-design-getting-started) - [Fully Orchestrating Databricks from Airflow](https://www.wearedevelopers.com/videos/336-fully-orchestrating-databricks-from-airflow) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers)
