Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster. 

This is Gen AI

Adyen seeks a Data Scientist to join our Generative AI team in Madrid. The mission of this team is to create a Generative AI platform enabling various applications with Large Language Models (LLMs). The team focuses on developing platform components for internal deployment and delivering end-to-end solutions for operational efficiency. Through use cases like support case routing and sentiment analysis, they showcase AI's adaptability across different domains within the organization, revolutionizing workflows and decision-making processes.

Our mission is to create a Generative AI platform at Adyen, supporting various applications based on LLMs. This involves developing platform-oriented components for deploying an LLM backend within Adyen's GPU cluster in Kubernetes, with features like monitoring, access control, rate limiting, prompt debuging and experiment tracking. We mainly use Open Source frameworks like HuggingFace and LangChain, and models like Llama or Mixtral. This involves developing platform components, but also delivering on some of the most promising use case across different areas within the company.

What you’ll do 

You will be responsible for building and interpreting algorithms that power data products at Adyen. Examples are: 

• Natural Language Processing techniques and LLMs to tackle text classification, sentiment analysis, summarization of Question-Answering retrieval.  
• Real-time anomaly detection based on time-series modeling, including transformer-based architectures of neural networks.
• Active Learning algorithms to facilitate faster and smarter annotation of datasets.
• Supervised and semi-supervised learning methods for inference on risk patterns.

Apart from that, you will: 

• Ensure efficient data preprocessing and ETL pipelines to create features that feed machine learning algorithms during training. 
• Set up experiments to adjust modeling decisions, perform exploratory analysis, tune hyperparameters, or validate hypothesis selection for the right metric set for each business problem. Report metrics and monitor performance to keep stakeholders updated and ensure a smooth model deployment in production.
• Iterate with merchants and product audiences creating algorithms that power state of the art machine learning based solutions, and be able to explain the reasons behind the executed inference.

Who you are

• You have 4+ years of professional experience as a DS Scientist.
• You have experience developing, training, validating, benchmarking and monitoring machine learning algorithms.
• Extensive knowledge of machine learning algorithms, including a deep understanding of statistical modeling, and Python development tooling and libraries: Pandas, Numpy, Scikit-learn, Pytest, PySpark, SQL, Airflow, MLflow, HuggingFace Transformers, Tensorflow or Pytorch.
• Familiarity with version control systems (e.g., Git) and collaboration tools.
• Adherence to coding best practices, including code reusability, documentation, and testing.
• An analytical thinker with a knack for understanding operational requirements and converting them into actionable ML solutions.
• Proactively taking the lead in projects, from ideation to deployment, while ensuring stakeholder collaboration.
• You can communicate complex outcomes with clarity over a wide range of audiences.
• We appreciate a forward-thinking mindset driven by experimentation and iterative development. A solid foundation in statistics and mathematics will serve you well in this role.
