Data Engineer - Stockholm

Build the data platform that drives the future of public transport

Keolis is responsible for public transport that moves thousands of people in Stockholm every day. Behind every bus, depot, and traffic flow, there is a vast amount of data. We are now strengthening our Advanced Analytics team and looking for a Data Engineer who wants to help build a robust and scalable data platform in Azure.

About the role

As a Data Engineer with us, you will work closely with the business to ensure a stable flow of information from buses, depot systems, and other operational sources into our lakehouse environment.

You will build and maintain data pipelines in Databricks, develop notebooks for transformation, and optimize flows to efficiently handle large volumes of data. The role involves both new development and further development of existing structures, focusing on quality, performance, and sustainable architecture. Our data platform is built in Azure with Databricks and a lakehouse architecture based on bronze, silver, and gold models.

You will be part of the Advanced Analytics team at our headquarters in Kungsholmen and work closely with analysts and the business. The role involves significant personal responsibility and the opportunity to influence how we develop our data architecture moving forward.

Your responsibilities

• Build, optimize, and maintain data pipelines in Databricks
• Develop transformations in Python and PySpark
• Ensure data quality and performance in large datasets

• Has worked on building and maintaining pipelines
• Has experience with lakehouse architecture and bronze, silver, and gold models
