About the Team We are a newly formed, forward-looking Cybersecurity Data Engineering & Enablement Team driving the future of our enterprise defense strategy. Our mission is to build a next-generation, centralized data lakehouse that unifies all security telemetry into a single, high-performance ecosystem. Operating across two specialized verticals—Data Engineering (ingestion, enrichment, and semantic layers) and Data Platform (foundational infrastructure, security architecture, and AI enablement)—we are designing a scalable, cloud-native foundation from the ground up. By combining cutting-edge data architecture with advanced analytics, we empower our threat hunters, data scientists, and incident responders with the real-time, trusted intelligence needed to protect the enterprise at scale. About the Role We are seeking a powerhouse Senior Data Platform Engineer to serve as our Subject Matter Expert (SME) for Data Platform and Lakehouse Architecture. In this role, you will be the architectural visionary and technical anchor of the infrastructure that powers our data ecosystem. You will not be building everyday data pipelines; instead, you will build the highly scalable, resilient, and self-service infrastructure that enables our Data Engineering and Analytics team to thrive. As a Lakehouse SME, you will bridge the gap between complex distributed systems and frictionless developer experiences, ensuring our platform is robust, cost-effective, and future-proof. Key Responsibilities Data Lakehouse Architecture & Strategy: Design, build, and optimize modern data lakehouse architecture from cloud native technologies, ensuring efficient separation of compute and storage. Developer Enablement (Platform as a Product): Build self-service tools, CI/CD pipelines, and infrastructure-as-code (IaC) templates that empower Data Engineers to deploy, test, and manage their pipelines autonomously with minimal friction. Data Platform Operations: Oversee the reliability, observability, security, and scaling of the core data platform. Implement robust monitoring and automated remediation for infrastructure bottlenecks. Complex Problem Solving: Deconstruct deep technical challenges related to high-volume data processing, distributed compute limits, and query optimization into manageable, algorithmic solutions. Technical Mentorship & SME Leadership: Serve as the definitive technical guide for the data organization. Evaluate new open-source or commercial technologies, design proofs-of-concept, and mentor engineers on platform best practices. Cross-Functional Collaboration: Partner directly with Data Engineering, Cybersecurity Engineering, Product teams to gather requirements, understand their daily friction points, and co-design infrastructure that supports their roadmaps. Cost Governance & Capacity Planning: Proactively monitor, alert, and optimize AWS data spend. Perform capacity planning to ensure the platform scales seamlessly with data volume growth. About You Basic Qualifications Experience: 5+ years in data platform engineering, DevOps, or Data Infrastructure, with at least 2 years operating in a senior or lead capacity. Lakehouse Expertise: 3+ years of hands-on experience building or migrating to modern data lakehouse architectures (Databricks, Snowflake, Delta Lake, Apache Iceberg) AWS Cloud Native Data Infrastructure: 3+ years of production-level experience across the AWS data stack, specifically AWS EMR (Spark/Presto/Trino tuning), AWS Athena, S3 infrastructure, and AWS Lake Formation. Infrastructure as Code (IaC): 3+ years of experience writing, deploying, and maintaining infrastructure using Terraform or CloudFormation in production environments. Data Warehousing Foundations: 3+ years of experience designing, administering, and optimizing modern cloud data warehouses (Snowflake, Databricks, or AWS Redshift) and cluster sizing/workload management experience is a plus Other Qualifications Languages: Advanced proficiency in SQL (performance tuning, query optimization) and Python or Bash for infrastructure automation. Experience setting up multi-region data lakes, cross-account data sharing, or data mesh architectures. Experience with open-source query engines like Trino or StarRocks.

Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in-office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote "home office" roles also have the opportunity to come together in our offices for important moments that matter.
