Data Warehouse Tech Lead

Role Summary

We're looking for a Data Warehouse Tech Lead to drive the technical vision and execution of our data infrastructure that powers decision-making across all of Lemonade.

You'll lead both the technology and the business coordination for our data warehouse — architecting scalable solutions while working closely with stakeholders and data providers to ensure our platform serves the entire organization's needs. This role combines deep technical leadership with strategic business partnership as we build Lemonade's next-generation data stack.

We believe three things matter for every role at Lemonade: drive to push through challenges, efficiency that keeps standards high while moving fast, and adaptability that lets you pivot with data and AI insights. These aren't buzzwords, they're how we actually work.

Our AI-first approach isn't just a tagline either. We're building the future of insurance with AI at the center, and we need people who are genuinely excited to learn and grow alongside these tools.

• Establish and implement best practices — set technical standards for data warehouse architecture, performance tuning, and development methodologies that guide the entire team's approach to building scalable data solutions
• Create and maintain sustainable data pipelines — build resilient systems capable of handling unstructured data and managing an evolving schema registry across diverse data sources
• Implement advanced data modeling — create robust data structures using methodologies like dimensional modeling, and optimize ETL/ELT processes for our semantic layer
• Establish data quality standards — build processes for schema evaluation, anomaly detection, and monitoring data completeness and freshness across all sources
• Lead cross-team collaboration — work directly with Data Engineers, ML Platform Engineers, Data Scientists, Analysts, and Product Managers to align technical solutions with business goals
