Data Engineer / Data Scientist

Jobtailor; Berlin; Vor Ort; EUR 70.000 - 110.000; Vollzeit

Zusammenfassung

Jobtailor in Berlin seeks a data engineer to drive end-to-end development of footfall data products, build scalable pipelines, and ensure data quality across large datasets.

You will own design decisions, optimize performance, and document data lineage. The role emphasizes independence, ownership, and ability to adapt to evolving analytics needs in a fast-paced tech environment.

Qualifikationen

• A solid foundation in Computer Science through a degree or equivalent hands-on experience.
• Strong Python skills, with excellent knowledge of pandas and writing clean, efficient, and maintainable code.
• A deep understanding of algorithms, data structures, computational complexity, and performance optimization.
• The ability to think critically about large-scale data processing, selecting the right tools and algorithms for datasets of varying sizes and computational constraints.
• Strong analytical and problem-solving skills, with an eye for detail and quality.
• The confidence to take ownership, work independently, and drive complex technical projects from idea to implementation.
• Bonus points if you also have experience working with geospatial data or GIS tools such as QGIS or ArcGIS, experience with distributed data processing frameworks - Dask experience is particularly valuable, experience building and maintaining production-grade data pipelines, familiarity with SQL and NoSQL databases, and exposure to cloud infrastructure and modern data engineering best practices.

Aufgaben
