About the role
Location: Berlin, Germany | Employment type: Office First | Team: Machine Learning Platform, Data & ML Platform
TEAM DESCRIPTION
SumUp's Machine Learning Platform team builds the foundational tools that every data scientist at SumUp relies on, from feature engineering and model training through to experimentation, monitoring, and serving. Right now, taking a model from idea to production can take months rather than weeks. You'll join a small, high-trust team of ML and ML Ops engineers who sit alongside our Data Streaming and Data Gateway teams, giving you first-hand visibility into how data moves and transforms across the business. If you enjoy building reliable and self-service platforms, this is a chance to shape infrastructure that touches nearly every model SumUp runs.
WHAT YOU'LL DO
Design and build ML platform tooling that supports feature engineering, training, experimentation, monitoring, and serving across both online and offline use cases
Simplify how data scientists create features, reducing reliance on complex Spark workflows through better abstractions or tooling
Standardise ML infrastructure and developer experience, replacing fragmented, ad hoc solutions with scalable, self-service components
Partner closely with data scientists to understand their workflows and pain points, translating them into concrete platform improvements
Celonis is the trusted platform to industrialize Enterprise AI. At our core is the Celonis Context Model — which combines process data, business knowledge, and intelligence into a living digital twin of the enterprise that AI can actually understand, turning AI's operational blind spots into operati
Mentor data scientists on best practices, helping drive adoption of the platform across teams
Collaborate with the Data Platform teams to keep ML initiatives aligned with wider data engineering work
YOU'LL BE GREAT FOR THIS ROLE IF...
More than 6 years of experience building production-grade ML infrastructure such as feature stores, training or orchestration frameworks, experimentation platforms, or model serving and monitoring systems
Strong proficiency in Python and ML libraries.
Experience with ML orchestration tools such as Metaflow, and familiarity with platform tooling such as MLflow, Kubeflow, Tecton, Chronon, or Airflow
Solid understanding of batch and real-time data processing patterns, for example Spark, Flink or Kafka
Comfort working with AWS cloud native services and infrastructure tooling such as Docker, Kubernetes, or Terraform
Track record of partnering with stakeholders to turn workflow pain points into reusable, self-service platform capabilities
