Senior Software Engineer (m/f/d) Data

• 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 building quality checks, lineage, freshness, and clear ownership from the start
• design schemas, 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 data and lift standards through active mentoring of mid-level and junior engineers
• tune pipelines, services, and data models for reliability, performance, and cost-efficiency

• 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
