Our partner is looking for a Data Scientist Early Hire, Full Model Ownership, B2C SaaS based in Spain. This is a unique opportunity to join a growing data team at an early stage and play a foundational role in shaping how machine learning and experimentation drive business outcomes. You will take full ownership of predictive models from problem definition through deployment, monitoring, and performance evaluation. Working closely with Product, Growth, Engineering, and Finance teams, you will help transform data into actionable insights that influence product strategy and revenue growth. The role offers significant autonomy, broad business exposure, and the chance to build scalable data science practices from the ground up. You'll work in a fast-paced, remote-first environment where experimentation, innovation, and measurable impact are highly valued. If you enjoy solving complex business problems with data and seeing your work directly influence company performance, this role offers exceptional ownership and visibility. Accountabilities: Design, build, validate, deploy, and monitor machine learning models that support key business objectives such as churn prediction, customer lifetime value forecasting, propensity modeling, uplift modeling, and recommendation systems. Own the complete machine learning lifecycle, including feature engineering, model development, evaluation, deployment, monitoring, and continuous optimization. Monitor production models, ensuring performance remains accurate and relevant as user behavior and product dynamics evolve. Design and analyze experiments, including A/B tests and causal inference studies, to evaluate business impact and support data-driven decision-making. Establish and improve experimentation frameworks, modeling standards, and best practices across the organization. Collaborate with data engineering teams to productionize models through scalable data pipelines, feature stores, and robust deployment processes. Translate analytical findings and model outputs into clear business recommendations for product, growth, finance, and leadership stakeholders. Identify opportunities to leverage AI and machine learning to improve customer experiences, product performance, and revenue outcomes. Ensure responsible use of customer data through privacy-conscious modeling practices and compliance with data governance standards. ## Related Videos - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [Machine learning in the browser with TensorFlowjs](https://www.wearedevelopers.com/videos/155-machine-learning-in-the-browser-with-tensorflowjs) - [Photonic Computing: Programming a New Class of AI Accelerators (incl.
