Senior Software Engineer - Data

What You Will Do

• Design, build, and operate Python-based data pipelines and services for market, reference, and index data across batch and real-time processing.
• Own the data lifecycle from ingestion and validation to transformation, orchestration, reconciliation, replay, and recovery.
• Deliver modular, testable, maintainable, and observable solutions with automated testing and reliable deployment pipelines.
• Build scalable and resilient distributed systems that handle large volumes, late or duplicate data, performance, and operational support.
• Collaborate with product, domain, architecture, QA, and SRE teams to improve data platforms, engineering standards, and modern development practices.

What You Bring

• Strong hands-on Python experience developing, testing, deploying, and operating production-grade data pipelines and services; Java is an advantage.
• Solid knowledge of data engineering, including extract-transform-load patterns, data modelling, transformation, lineage, data quality, orchestration, and batch and real-time processing.
• Experience with distributed, data-intensive systems, including scalability, resilience, performance, observability, idempotency, reconciliation, and recovery.
• Strong software engineering practices, including modular design, automated testing, version control, continuous integration, and technical documentation.
• Experience with Apache Airflow or Metaflow and financial-market, time-series, or index data is an advantage; relevant degree or equivalent experience, fluent English, and German as a plus.
