You will join a growing AI team of 10 colleagues with a core mission to turn data and AI into measurable business value.
Your primary role will be to build, improve, and productionize forecasting models that support business-critical decisions across Flatpay and our merchants. A key focus will be revenue forecasting across 100,000+ merchants, where forecasting plays an important role in areas such as shift planning, table booking optimization, and operational decision-making for merchants.
This role is a good fit for someone who enjoys working with real-world time series problems, cares about production-quality machine learning, and wants to build models and product features that are used directly in business and product workflows.

Permanent employee
About the job
What you'll do
- Build, improve, and maintain production-grade time series forecasting models using Python, LightGBM, XGBoost, MLflow, and Databricks.
- Work on revenue forecasting for 100,000+ merchants across different markets, merchant types, and business patterns.
- Develop product features on top of forecasting models that support merchant-facing optimization use cases such as shift planning and table booking.
- Assist with and run other time series projects across areas such as churn prediction, TPV forecasting, upsell opportunities, and more.
- Design robust feature pipelines, model training workflows, evaluation frameworks, and monitoring approaches for forecasting models in production.
- Collaborate closely with data engineers to ensure models are built on reliable, scalable, and well-structured data foundations.
- Work with business stakeholders, product teams, and commercial teams to understand forecasting needs and turn them into practical data science solutions.

- You are comfortable building models using Python and libraries such as LightGBM, XGBoost, NumPy, and scikit-learn.
- You have experience with model tracking, experiment management, and production workflows using tools such as MLflow.
- You are comfortable working in Databricks or similar cloud-based data platforms.
- You have strong PySpark, Pandas and SQL skills and are comfortable working with large, structured datasets.
- You have experience with extracting structured features from unstructured data using LLMs and integrating that into productionized forecasting.
- Through experience you have a refined intuition when to do exotic feature engineering and none-stand modelling approaches - and when its best to stick to the fundamentals.
