This person will be responsible for understanding the current-state data landscape, defining the future-state architecture, and designing scalable data models and integration patterns across ad delivery, audience segmentation, campaign reporting, inventory, and billing. The ideal candidate has strong experience designing enterprise data foundations, conducting exploratory data analysis, architecting batch and real-time data pipelines, and integrating complex legacy systems with modern cloud-native platforms. Experience designing data models for real-time inventory, order management, logistics, or supply chain systems is required. This is a contract role requiring onsite work in Los Angeles three days per week. What you will do: * Design scalable conceptual, logical, and physical data models for ad delivery, audience segmentation, campaign reporting, inventory, and billing. * Map data relationships, dependencies, and flows across existing systems and ensure critical dependencies are preserved in the future-state architecture. * Conduct exploratory data analysis across raw and existing datasets to develop a comprehensive understanding of the current-state data landscape. * Profile existing data sources, inventory and characterize data assets, assess data quality, and identify gaps, inconsistencies, duplication, and integration risks. * Define data ingestion, transformation, and orchestration patterns across batch and real-time data streams. * Design data architectures that support high-volume events such as ad impressions, click activity, audience signals, inventory changes, and campaign transactions. * Architect cloud-native data solutions using AWS services and technologies such as relational databases, graph databases, retrieval-augmented generation, and vector databases. * Define integration patterns between legacy systems and a modern microservices-based platform. * Ensure data interfaces, schemas, contracts, relationships, and system dependencies are clearly defined and documented. * Establish data governance standards across lineage, cataloging, data quality, access controls, privacy, security, and lifecycle management. * Collaborate closely with cloud services, engineering, architecture, product, and business teams across multiple workstreams. * Maintain data architecture artifacts including entity relationship diagrams, data flow diagrams, schema definitions, data dictionaries, and architecture decision records. ## Related Videos - [Why Your AI Agent Keeps Hallucinating Your Data: Building Deterministic Context Layers](https://www.wearedevelopers.com/videos/2055-why-your-ai-agent-keeps-hallucinating-your-data-building-deterministic-context-layers) - [A Data Mesh needs Open Metadata](https://www.wearedevelopers.com/videos/505-a-data-mesh-needs-open-metadata) - [Microservices: how to get started with Spring Boot and Kubernetes](https://www.wearedevelopers.com/videos/242-microservices-how-to-get-started-with-spring-boot-and-kubernetes) - [Modern Data Architectures need Software Engineering](https://www.wearedevelopers.com/videos/1030-modern-data-architectures-need-software-engineering) - [Data: The Deciding Factor in AI Success](https://www.wearedevelopers.com/videos/100310-data-the-deciding-factor-in-ai-success) - [Parquet, Delta, Iceberg & Ducklake - An introduction for developers](https://www.wearedevelopers.com/videos/100075-parquet-delta-iceberg-ducklake-an-introduction-for-developers) ## Related Articles - [Making Data Warehouses Fast: A Developer’s Story](https://www.wearedevelopers.com/magazine/107-making-data-warehouses-fast-a-developer-s-story) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries)
