We strive to create a pleasant and collaborative working environment in which every employee feels comfortable and is happy to contribute to our vision: "Until every human has their health". If you are looking for a meaningful career that matches your values, join our team and start your #Redcareer today. About the role As a Senior Data Scientist, you will play a key role in building production-grade data science and machine learning solutions that directly influence critical business decisions and customer experiences. You will work on one of our high-impact products, partnering closely with product, engineering, and business teams. Rather than focusing on isolated analyses, you will be involved in products end to end — from problem framing and data quality to modeling, deployment, and ongoing monitoring in production. This role is designed for a strong generalist who enjoys working across domains, applying solid statistical and machine-learning foundations to real-world problems, and turning ideas into reliable systems. Job Description About your tasks Work in a product with colleagues from our Data & AI department and collaborate closely with product managers, engineers, and domain experts to translate business problems into data-driven solutions. Design, build, and operate end-to-end data science and machine learning solutions, from initial problem definition to production and iteration. Work hands-on with complex, real-world datasets, addressing challenges such as data quality, missing data, bias, and changing data distributions. Develop, evaluate, and improve statistical and machine-learning models, making well-reasoned trade-offs between model complexity, performance, scalability, and maintainability. Design and analyze A/B tests and experiments, including hypothesis definition, metric selection, statistical evaluation, and interpretation of results. Define and implement robust evaluation frameworks, including appropriate baselines, metrics, and validation strategies. Support bringing models into production using our cloud-based stack and ensuring they are reliable, monitorable, and maintainable over time. Communicate results, assumptions, and uncertainty clearly, enabling informed decision-making rather than black-box outputs. Support the team by sharing knowledge, setting best practices, and acting as a technical sparring partner for other data scientists. Qualifications About you You have several years of hands-on experience as a Data Scientist, working on machine learning or advanced analytical problems in production. You have a strong foundation in statistics and machine learning and can apply it pragmatically to real-world problems. You understand how to combine offline model evaluation with online experimentation to assess real-world impact. You enjoy working close to the business and can explain complex topics clearly to non-technical stakeholders. You take ownership, work proactively, and are comfortable navigating ambiguity. You are curious and eager to learn, but also careful and conscientious in how you work. You value collaboration, give and receive feedback openly, and enjoy helping others grow.
