(Senior) Data Engineer (m/f/d)

You'll take ownership of Corego's data platform on Databricks — developing it, keeping it running reliably, and growing it as our data and AI needs evolve. Day to day, this includes:

• Developing and evolving the platform's ingestion, lakehouse architecture, transformation pipelines, and orchestration
• Building and maintaining the data models and pipelines that power analytics, reporting, and machine learning workloads across Corego Cloud (payments, access control, network, POS)
• Maintaining strong data quality, testing, and CI/CD practices across the platform
• Defining and evolving access control, data governance, and security standards (e.g. Unity Catalog) On the operations side, you'll:
• Run the platform in production — monitoring, incident response, and performance/cost optimization (cluster and compute management)
• Extend the platform with new data products, pipelines, and use cases as Corego's data and AI roadmap grows
• Collaborate with product management and developers to integrate data/ML outputs into business processes and customer-facing products
• Own data reliability and scalability as usage and event volumes grow

• Degree in Computer Science, Data Engineering, or another relevant technical field
• 3+ years of hands-on data engineering experience designing and building data pipelines
• Practical experience with Databricks (or an equivalent Spark-based platform), including PySpark and workflow orchestration
• Experience with infrastructure-as-code and DevOps practices for data platforms
• Experience with cloud platforms, ideally Microsoft Azure
• Understanding of data security and governance best practices
• Strong analytical thinking, attention to detail, and ability to manage your own workload
• Ability to work independently and take initiative, while fitting well within the team
• Proficiency in English
