ROLE OVERVIEW Zeta Global is seeking a Lead Data Engineer to build and scale healthcare-focused applications and data systems that power audience intelligence, activation, measurement, and reporting across both HCP and DTC workflows. This is a hands-on technical leadership role operating at the intersection of distributed systems, data engineering, and healthcare domain constraints. You will design and deliver systems that integrate identity, audience data, and campaign performance while meeting strict requirements for privacy, compliance, and reliability. The ideal candidate brings strong system design depth, experience building data-intensive platforms, and the ability to lead through architecture and execution in regulated environments. What You’ll Build Applications supporting HCP and patient / direct-to-consumer (DTC) audience discovery, segmentation, and activation Scalable data pipelines for ingestion, normalization, and enrichment of healthcare datasets Identity resolution and data linkage services across fragmented data sources Reporting, attribution, and measurement systems connecting campaigns to outcomes APIs and services enabling downstream activation, analytics, and partner integrations Healthcare Cloud and data-mapping architecture across claims/Rx, NPI/HCP, patient, media-exposure, brand, and connector datasets. Healthcare-specific semantic cubes, governed views, data contracts, and domain APIs consumed by Vertical Apps; front-end applications should consume stable domain APIs rather than query raw stores or Cube directly. Identity resolution, match-rate measurement, medical-code mapping, and approved joins under CERT/HIPAA rules. Foundational data products for NPI onboarding, PLD reporting, script reporting, HCP/Patient intelligence, journeys, and Next Best Action. Key Responsibilities Define and maintain the healthcare data architecture, interface contracts, ADRs, schemas, and staged delivery plan.

Lead design and code reviews, mentor the Senior Data Engineer, and coordinate dependencies across the pod. Support compliance evidence, annual audits, US data-residency controls, and stoplight decisions: Start, Stop, or Requires CERT.
