• Write data transformations in SQL/Python to generate data products consumed by Analytics, Marketing Operations, and Sales Operations teams
• Design, build, and operate large-scale Spark and PySpark workflows for batch and streaming data processing across Databricks and cloud environments
• Optimize Spark job performance — tuning partitioning, shuffle, caching, and resource allocation for production-grade reliability and efficiency
• Define and enforce data engineering standards, patterns, and best practices across the team
• Design systems with long-term maintainability in mind: clear contracts, testable components, and thoughtful failure modes
• Collaborate with platform and infrastructure teams to evolve the underlying architecture of Samsara's enterprise data ecosystem
• Build and maintain MCP (Model Context Protocol) servers that expose Samsara's data assets and engineering workflows to AI models and internal tooling
• Collaborate with platform teams to integrate agentic workflows into the data engineering lifecycle
