Intermediate/Senior Data Engineer - Scientific Engine - CDI (Starting November 2025)

<p><strong>ABOUT DESCARTES UNDERWRITING</strong></p><p>Descartes was born out of the conviction that the ever-increasing complexity of risks faced by corporations, governments and vulnerable communities calls for a renewed approach in insurance. Our team brings together industry veterans from the most renowned institutions (AXA, SCOR, Swiss Re, Marsh, Aon, ...) and scientists on top of their field to bring underwriting excellence. After 5 years of existence, Descartes has secured a leading position in parametric insurance for weather and climate-related risks utilizing machine learning, real-time monitoring from satellite imagery &amp; IoT. After a successful Series B raise of $120M USD, we launched Descartes Insurance, a 'full stack' insurer licensed to underwrite risk by the French regulator ACPR. With a growing corporate client base (400+ and counting), our diverse team is headquartered in Paris and operates out of our 18 global offices in North America, Europe, Australia, Singapore, Hong Kong and Japan. Descartes is trusted by a panel of A-rated (re)insurers to carry out its activities.</p><p><br/></p><p><strong>ABOUT YOUR ROLE </strong></p><p>Due to our consistent growth, we are expanding our Data, Software and DevOps team. We are seeking profiles dedicated to data engineering. At the core of the development of our scientific engine modeling climate phenomena, your main missions will be to create, improve and maintain the data pipelines used to train our model and infer the different scenarios to make a climate risk assessment. You will have to take initiative and assess the viability of proof-of-concept projects.</p><p>You will have to work with data scientists and software engineers to run and develop our models. You will be working alongside DevOps engineers to reliably put models in production and selected the compute/store instance needed to perform these tasks. Your secondary mission will be to automate the flow of information between the tech and business to monitor climate events.</p><p><strong>🔔</strong> <strong>KEY MISSIONS </strong><strong>🔔</strong></p><ul> <li>Design, setup, and maintain:<ul> <li>Data pipelines and associated datalakes;</li> <li>Connections to external and internal APIs;</li> <li>Associated CI/CD and release pipelines;</li> <li>Notification tools to inform the team of the status of the operations.<br/></li> </ul></li> <li>Propose and setup data storage, data processing and data visualizing tools including:<ul> <li>Assessing the pains and needs of the teams;</li> <li>Benchmarking different solutions;</li> <li>Assessing the security, price and reliability of data architecture;</li> <li>Following the development the evolution of technologies on the topic;</li> <li>Forecasting and tracking cloud spend.<br/></li> </ul></li> <li>Participate in:<ul> <li>Tech stack evolution;</li> <li>Discussions with tech partners;</li> <li>Training of other tech teams;</li> <li>Support and debug of internal users.</li> </ul></li> </ul><p><strong>TECH STACK </strong><strong>🖥️</strong></p><ul> <li>Cloud provider: GCP</li> <li>Code versioning tool: Git + Gitlab</li> <li>OS: Windows</li> <li>Container: Docker</li> <li>Container orchestrator: Kubernetes</li> <li>Code base: Python</li> <li>Notification tool: Slack</li> </ul><p><strong>DATA STACK </strong></p><ul> <li>Types: images, time series, data frames, etc.</li> <li>Pipeline orchestrator: Apache Airflow </li> <li>Data stores: Cloud SQL, FireStore, BigQuery</li> </ul><p>In our project, data is collected by sensors (satellite, weather station, IoT).
