Overview: We are building the next generation of our platform — an AI-native data foundation that will power intelligent agents, living user profiles, digital twins, and conversational research analytics. This is a greenfield, foundational build that will define the future of the company. We are building a new data engineering team reporting directly to the VP of Engineering. You will be a founding member of this team, responsible for designing and building the Databricks-first data lake and pipeline infrastructure that every future AI product will depend on. This is not a maintenance role. We need engineers who are productive from day one — experienced enough to make architectural decisions independently and drive the build without step-by-step direction. Key Responsibilities: Data Lake & Warehouse Architecture A multi-tenant data lake and warehouse that unifies all research data — surveys, qualitative feedback, CRM, media transcripts, and more — in a structured, AI-consumable format Tenant-isolated data architecture where enterprise client data is structurally separated at the storage and query layer Provenance-aware data models where every data point carries full traceability back to its source Data Ingestion & Pipelines Batch ingestion pipelines that migrate and continuously sync data from existing relational databases and cloud storage into the new lake architecture A nightly profile enrichment pipeline that rebuilds living user profiles from all data sources within each client account Data Access & AI Enablement Data access layers serving AI agents via MCP, qualitative search via RAG pipelines, statistical computation tools, REST APIs, and bulk export Your Success Metrics: Quickly integrates with the engineering team and contributes meaningfully to the data platform build Takes ownership of assigned pipeline and infrastructure work end-to-end, from design through production Brings architectural recommendations and solutions proactively, rather than waiting for direction Demonstrates strong collaboration and communication across engineering and product teams Who you’ll work with?
