• 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

• 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
