📋 Description

• Semantic Model Architecture : Design and evolve the semantic modeling layer that serves as the single source of truth for metrics, dimensions, entities, and business logic across all data products. • Data Product Enablement : Architect how the semantic layer is consumed across distinct product surfaces such as Reporting (high-performance BI platform for customers), and Agentic Analytics (metadata-rich, discoverable interfaces that enable AI agents to reason over and query the semantic layer). • Performance & Scale : Own query performance, materialization strategies, pre-aggregation patterns, and cost optimization. Ensure the semantic layer is highly performant and scalable as data volumes and consumer demand grow. • Platform & Governance : Build the semantic layer as a true platform experience: self-service metric onboarding, developer-friendly abstractions, clear documentation, data validation, and governance guardrails. • Technical Leadership : Operate as a technical leader across the Data & Reporting Platform organization. • AI-Augmented Engineering : Use AI coding tools (Claude, Cursor, Copilot) as a core part of your daily workflow.

🎯 Requirements

• 10+ years of experience in Software Engineering or Data Engineering roles, including experience with large-scale, high-traffic, fault-tolerant systems. • Deep experience with semantic modeling, data engineering, data lakehouse, and data product development. • Track record of building platform-level abstractions consumed by multiple product teams. • Strong experience with the DBT ecosystem. • Expert-level SQL and Python skills. • Experience with query optimization, materialization strategies, and performance tuning at scale. • Experience with modern data platform technologies: Snowflake, ClickHouse, or similar OLAP/columnar engines. • Familiarity with Spark and streaming platforms (Kafka, Kinesis). • Experience designing APIs and interfaces for domain specific data products. • Demonstrated proficiency with AI coding tools (eg Claude, Cursor) as part of your regular engineering workflow; not just familiarity, but active daily use. • Strong communication and technical writing skills. • Ability to empathize with users and champion for their experience. • B.S., M.S., or PhD in Computer Science or a related field. • Highly preferred Experience building semantic layers that serve both human analysts and programmatic/AI consumers. • Experience with data governance frameworks, metric versioning, or data product catalogs. • Familiarity with LLM-friendly data interfaces; designing schemas and metadata that enable AI agents to discover and query data effectively. • Experience with data validation and quality frameworks (e.g., Monte Carlo, Great Expectations). • To effectively support our international teams, this position requires flexibility to overlap with US working hours as needed.
