In this role, you will make architectural, design, and operational decisions that shape how analysts, engineers, and business stakeholders interact with data at Cardlytics. As data consumption increasingly shifts toward AI and agentic applications, you will also shape the platform's evolution into an AI-ready foundation - spanning the semantic layer, feature store, and data ontology that these systems depend on. You will combine deep expertise in industry-leading data platforms with the ability to provide technical leadership, define platform standards, and act as the primary technical partner for diverse user groups across the organization.\nYou will:\nArchitecture and design: Design and evolve the Cardlytics next-generation architecture; establish reference architectures and standards for batch, streaming, ML, and AI/agentic workloads.\n\nAI-ready data platform: Build out the semantic layer, feature store, and data ontology that make Cardlytics data consumable by AI/agentic applications; enable governed, self-service access for both human and machine (LLM/agent) consumers.\n\nUser enablement: Serve as the primary technical partner for analysts, engineers, and business users; develop self-service guides, onboarding materials, and best-practice documentation to reduce friction across all user groups.\n\nTechnical leadership: Set technical direction for the platform and mentor engineers across the data and platform teams; drive engineering excellence and best practices, and manage the vendor relationship.\n\nPerformance and reliability: Define monitoring standards and SLAs, lead performance tuning for Spark jobs, open table formats (e.g. Delta, Hudi), and SQL query engines; own incident response and root-cause analysis.\n\nGovernance and security: Drive adoption of a unified governance layer (e.g., Databricks Unity Catalog) for centralized RBAC, column-level security, data lineage, and metadata management; implement and maintain security best practices including encryption and audit logging.\n\nPlatform standards and governance: Define the operating model and guardrails for the managed lakehouse platforms (including Databricks on AWS) - compute policies, access model, catalog structure, and cost governance - with day-to-day administration executed by the platform and domain teams working within those standards.\n\nInfrastructure as code: Own the CI/CD strategy for lakehouse and data platform deployments (Terraform, GitHub Actions, and platform-native packaging such as Asset Bundles); enforce DevOps practices across engineering teams.\n\nYou have:\n7+ years of experience in data engineering or data platform roles, with at least 2 years in a technical lead or architecture capacity.\n\nDeep, hands-on expertise with the leading industry platforms, frameworks, and tools: Databricks, AWS EMR or similar, Delta Lake, Unity Catalog, Spark (PySpark), and SQL; with a solid understanding of compute/cluster management on AWS.\n\nProven experience designing and delivering Lakehouse architectures and large-scale ELT/ETL pipelines in production environments.\n\nProficiency in Infrastructure as Code tools, such as Terraform.\n\nDemonstrated experience supporting diverse stakeholder groups including analysts, engineers (including ML engineers), and non-technical business users.\n\nStrong understanding of data governance, data modeling, and cloud security best practices.\n\nExcellent communication and collaboration skills, with the ability to translate technical concepts for non-technical audiences.\n\nNice to have:\nExperience designing or operating a semantic layer, feature store, or data ontology / knowledge graph in a production environment.\n\nFamiliarity with managing data for ML systems and AI/agentic applications, such as training pipelines or inference for LLM-powered and agentic tools.\n\nTechnical Environment\nWe primarily use macOS and Google Workspace (Docs, Sheets, Slides). While our preferred platform is macOS, we support both macOS and Windows. Familiarity with or willingness to work within this environment is required.\nCore Values\nOur shared values are the driving force behind everything we do. Across all roles, we are looking for teammates who embody these values:\nCustomer and partner first\n\nAct with urgency and focus\n\nIntegrity with our partners and data\n\nAccountability even when challenged\n\nEmpowerment over hierarchy\n\nGrowth over comfort\n\nBenefits and Perks\nFlexible paid time off plus company holidays\n\nMedical, dental, and vision insurance begins on your first day\n\n401(k) retirement plan with company match, plan also includes a student loan debt repayment option\n\nEmployee Stock Purchase Plan\n\nEducational assistance for continuing education\n\nLifestyle Spending Account for physical, emotional, and financial wellness (like gym memberships, home down payments, art classes, park passes, and more!)\n\nComplimentary Calm app subscriptions to support employee mental health and wellbeing\n\nAs an equal opportunity employer, Cardlytics is committed to diversity, equity, and inclusion.
