Zusammenfassung

Axel Springer Tech GmbH in Berlin is seeking an experienced backend/data engineer to design, build, and operate end-to-end data products powering our media and advertising platforms. You will work in a Python-first, cloud-native stack and collaborate with engineers, data scientists, analysts, and product partners.

You will own systems, ensure data quality, implement APIs and data contracts, mentor junior engineers, and optimize pipelines for reliability, performance and cost efficiency.

Qualifikationen

• A degree in computer science, engineering, or a related field; equivalent expertise proven through experience and impact is equally valued.
• Senior-level experience delivering and operating backend systems, data products, APIs, services, or pipelines end-to-end in a cloud environment such as AWS, GCP, or Azure.
• Strong software engineering fundamentals with Python, writing clean, well-tested, maintainable code, and the ability to quickly pick up Go and other tools; experience with cloud data, lakehouse platforms, and high-throughput processing is a plus.
• Whether you come as a senior backend engineer moving into data or a data engineer with meaningful backend experience, you bring either solid depth in data modeling, schema evolution, incremental and idempotent processing, and late data handling, or strong transferable instincts and a genuine drive to go deeper.
• Sound judgment on APIs, data contracts, schemas, and ownership boundaries, including the ability to reason about compute cost and trade-offs, not just whether a system runs.
• Data-trust instincts: you treat quality checks, lineage, freshness, observability, and documentation as first-class deliverables and operate data products like real production systems.
• Strong collaboration and communication skills, including comfort working with non-engineers, valuing documentation and quality as glue work, and mentoring engineers at a range of levels.
• You take responsibility for outcomes, partner with your team and stakeholders to align on direction, and drive work forward.

Aufgaben

• build data products as production software by designing, implementing, testing, deploying, and operating end-to-end systems
• bring backend engineering rigor to data through clean code, sensible APIs, automated testing, and strong observability
• own systems end-to-end and stay responsible for incidents, operational quality, performance tuning, and continuous improvement
• make data trustworthy by buildingquality checks, lineage, freshness, and clear ownership from the start
• designschemas,data contracts and domain models that evolve safely, handle late data, and reflect real business questions
• partner with product, engineering, and data science to deliver reliable, high-quality dataand lift standards through active mentoring of mid-level and junior engineers
• tune pipelines, services, and data models for reliability, performance, and cost-efficiency
