We are part of Erste Group - the largest banking group in Central and Eastern Europe with more than 2,500 branches and over 45,000 employees. Our more than 2,000 IT experts and enthusiasts are the bank's Digital Muscle.

In our cluster we are developing a future of internet banking - an AI driven banking chatbot Hey George to help millions of our customers in Europe with their daily banking requirements as well as with improving their financial health.

We have already achieved significant results with our chatbots, but as you can imagine, this poses many wonderful questions for Data Science - how do we measure the quality and correctness of Hey George answers? Especially for questions requiring financial calculations? How do we protect Hey George from attacks? How can we further optimize it to become a personalized financial assistant helping our clients becoming financially stronger?

As a Data Scientist, you will closely collaborate with colleagues from business and IT to answer these questions with data-driven solutions as well as search for new questions that will help improve our company. We will rely on you to build machine learning (ML) models or other solutions to identify patterns in our data and extract valuable business insights. In this role, you should be highly analytical with a knack for math and statistics. Critical thinking and problem-solving skills are essential for interpreting data. We also want to see a passion for modelling and algorithms.

What to do:

* Analyse chatbot usage and its user's requirements (in collaboration with product colleagues) in order to drive chatbot feature development across six markets.
* You deliver typical data science tasks in data driven projects, including data pipelines and monitoring engineering, development of predictive models and learning from data, text classification, conversation understanding etc.
* You are ready to deliver in team and independently, proactively searching for assistance of team and partner departments to deliver on time.
* You deliver and support in all phases of the full Data Science process, but with different level of expectations and time allocation, where data and feature engineering, as well as search for optimal parameters within chosen model class take the most of time.
* You are open to learn how to serve banking business owners, even in international projects, through strong interest in data and technology.

You check these boxes:

* A genuine curiosity and thinking about how to bring innovative problem solutions into practical application in a banking industry.
* Good understanding of statistical methods and common machine learning algorithms.
* In-depth experience with data analysis and visualization.
* Experience in development and implementation of generative AI solutions (prompt-engineering techniques for Large Language Models, training of LLMs).
* Good knowledge of Python, Spark and SQL (with practical experience).
* Expertise in Databricks.
* Practical experience with agentic systems (e.g. LangGraph).
* Practical knowledge of JavaScript (since our backend runs on Node.js).
* Basic understanding of the banking business.
* Language skills: English full proficiency, German or Czech intermediate is a plus.
* A Bachelor's or Master's degree with a focus on quantitative disciplines.
* Minimum of 3 years practical experience as a Data Scientist.

Why you will like us:

* Possibility to benefit and learn from our international, talented and passionate community at Erste
* Interest groups and clubs: Take part in discussions and get involved in projects. Numerous interest groups invite you to engage with a topic
* Health Care - Taking care of your health is important. That's why we contribute to your above standard medical examination and provide a helpline in case of hard lifetime situations. You also receive a salary compensation during sick leave

But this is just a formality, we are more than happy to discuss your actual expectations.
