Key Responsibilities

As a Data Engineer, your primary responsibility is the architecture and implementation of data platforms that support the exchange's mission-critical functions. You will be responsible for building scalable ETL/ELT processes that transform raw financial data into actionable insights for internal analysts and external clients. This involves working closely with Data Scientists to prepare datasets for modeling and with Software Engineers to integrate data products into customer-facing applications.

Beyond coding, you are expected to take an active role in the maintenance and evolution of the data infrastructure. This includes monitoring system performance, troubleshooting production issues, and ensuring that all data handling complies with stringent European financial regulations. You will drive initiatives to improve data quality and governance, ensuring that the organization can trust the data it uses for trading, risk management, and regulatory reporting.

Collaboration is a daily requirement. You will participate in agile ceremonies, contribute to architectural reviews, and mentor junior engineers. Your role is pivotal in bridging the gap between raw data sources and the business intelligence that drives Deutsche Börse Group forward.

Role Requirements & Qualifications

A successful candidate for the Data Engineer position typically possesses a strong foundation in computer science and extensive experience in data-intensive environments.

• Technical Skills – Expert-level knowledge of Python and SQL is essential. You should have hands-on experience with Azure (Data Factory, Synapse, Logic Apps) and Databricks (Spark, Delta Lake). Familiarity with CI/CD tools like Azure DevOps or GitHub Actions is highly valued.

• Experience Level – Most successful candidates have at least 3–5 years of experience in data engineering or a related field, preferably within the financial services or another highly regulated industry.

• Soft Skills – Strong command of the English language is required, as you will work in an international environment. You must demonstrate proactive communication and the ability to work independently in a hybrid or remote setting.

• Must-have skills – Azure cloud ecosystem, Spark/Databricks, and advanced SQL optimization.

• Nice-to-have skills – Experience with Java/Scala, knowledge of financial market data formats (e.g., FIX, SWIFT), and certifications in Azure Data Engineering.
