Santander · Boadilla Del Monte, Spain · 3mo ago
IT STARTS HERE
Santander (www.santander.com) is evolving from a global, high-impact brand into a technology-driven organization, and our people are at the heart of this journey. Together, we are driving a customer-centric transformation that values bold thinking, innovation, and the courage to challenge what’s possible.
This is more than a strategic shift. It’s a chance for driven professionals to grow, learn, and make a real difference.
Our mission is to contribute to help more people and businesses prosper. We embrace a strong risk culture and all our professionals at all levels are expected to take a proactive and responsible approach toward risk management.
THE DIFFERENCE YOU MAKE
Santander’s Data & AI Science (DAISci) team is the scientific engine of the bank’s AI transformation. DAISci develops, tests, validates, and translates emerging AI methods and models into products and platforms that redefine how the bank learns, decides, and operates at global scale.
DAISci ensures learning systems and agents scale and remain reliable over time, and translates frontier AI research into trusted, large-scale decision systems that reshape how the bank learns, decides, and operates.
This role offers a rare opportunity to apply frontier AI to reshape financial systems.
Main Responsibilities:
The SENIOR AI SCIENTIST IN ADVANCED ANALYTICS leads the evolution of traditional data science practices into AI Science, leveraging modern learning systems and agentic architectures to transform how models are designed, evaluated, and operated. The role is designed for a strong individual contributor capable of combining classical analytical rigor with emerging AI methodologies to deliver scalable, production-grade intelligent systems.
The Senior AI Scientist is responsible for framing business challenges such as scientific problems, designing experimental strategies, and deploying advanced modeling approaches that go beyond conventional machine learning pipelines. This includes the application of modern AI techniques such as graph-based learning, reinforcement learning, synthetic data generation, advanced retrieval methods, and Generative AI, when appropriate to the problem.
Working hands-on within project squads, the Senior AI Scientist contributes directly to data preparation, model design, experimentation, validation, and operationalization. The role combines execution with leadership: guiding project direction, mentoring peers, and ensuring that methodological choices are grounded in evidence and aligned with risk and governance requirements.
The position requires close collaboration with engineering, product, and business stakeholders to ensure that models evolve from prototypes into reliable systems that adapt over time. The emphasis is on scientific rigor, measurable impact, and long-term system behavior, rather than isolated model delivery.
