Senior Data Scientist

Job Description:

About Banking Processes and Operations

As part of our ongoing digitalization transformation, we are optimizing and redefining the way that banking processes are handled. We are implementing advanced workflow management systems to streamline operations, reduce manual tasks, and boost efficiency.

Advanced Optimization Algorithms and AI play a crucial role in this transformation.

Your profile

Experienced Data Scientist, able to conduct research; generate requirements; solution design; technical concepts and architectures; and delivery of solutions.

We`ll trust you to:

• Smoothly integrate within an Agile Development Team, consisting of DEVs, QAs, BAs, Data Scientists.
• Maintain and enhance existing Optimization Algorithms (Constraint Integer Programming) based on SCIP.
• Conceptualize and design ML models to optimize and transform bank processes in the Operations Area
• Contribute on both technical and business process transformation by introducing data science & ML/AI with focus on language models, pattern recognition, forecasting, optimization methods and reinforcement learning agents.
• Come with a good understanding of the current software development state of the art and contribute to architectural design of the automation of processes and workflows in a microservice environment.
• Translate business requirements into technical concepts; research and implement appropriate ML algorithms; apply suitable frameworks for solving constraint integer programs.
• Monitor performance of the models in production; ensure no degradation occurs below established metrics and retrain when needed.
• Work with Data Engineers to deploy and maintain models in production or to analyze/build data pipelines for new data sources.
