We are building a multi-tenant data platform that serves as the single source of truth for marketing data across every client and program. At its center is a universal schema that stores cross-organization, cross-company data in one system of record.You will own this platform end-to-end: the API ingestion layer for both self-service third-party connectors and proprietary first-party client data, the transformation pipelines, internal and client-facing dashboards, agentic automation, and monitoring infrastructure. You report directly to a board member and work across senior leadership to deliver validated visibility fast.What You'll DoA massive central schema normalizing cross-client, cross-org marketing data into a canonical model with multi-tenant isolation, versioning, and cross-client benchmarkingA self-service connector framework: new clients authenticate and connect their own third-party platforms (Meta, Google, LinkedIn, HubSpot, Salesforce, GA4, Shopify, etc.) without engineering involvement A first-party data ingestion API where clients push proprietary data (CRM exports, offline conversions, custom events) through validated transformation pipelines into the universal schemaInternal and client-facing dashboards: white-labeled, permission-scoped, self-service, blending first-party and third-party data into unified marketing attribution viewsAgentic automation: AI agent orchestration pipelines (agent-of-agents patterns) that automate data validation, anomaly detection, report generation, and cross-pipeline coordinationFull observability: alerting, health checks, data freshness SLAs, and self-healing mechanisms across the platformQualificationsExpert in abstraction and system design: you take messy, multi-source data landscapes and design clean schemas, APIs, and interfaces that make them tractable at scaleDeep marketing data fluency: attribution models (MTA, MMM, last-touch, first-touch), conversion tracking, UTM structures, ad platform APIs, cross-platform data reconciliationStrong product and productization instincts: multi-tenant architecture, user auth (OAuth, RBAC, SSO), self-service onboarding, schema mappingCloud architecture fluency (AWS preferred): serverless, containers, managed databases, API gateways, IAMAI-native and agentic: you build with Claude, Cursor, and similar tools daily. You understand agent orchestration, agent-of-agents patterns, and programmatic automation of complex multi-step workflows.
