The Staff Data Engineer will design and evolve core components of the company's lakehouse and data platform, ensuring data is structured and governed effectively for analytics and AI systems.

Responsibilities:

• Design and evolve the Iceberg-based lakehouse architecture to balance scalability, cost, performance, and maintainability
• Define and promote standards for table design, partitioning, schema evolution, optimization, and data layout
• Lead architectural efforts spanning batch, streaming, and event-driven data processing where they deliver business value
• Drive the design and delivery of complex, cross-team initiatives, enabling teams to move independently within established architectural guidance
• Build vs. Buy: Evaluate and integrate technologies
• Define how datasets, pipelines, features, and models are described, related, and governed using shared metadata
• Lead the adoption and integration of open-source metadata and catalog tools (e.g., OpenMetadata or similar ecosystems)
• Establish metadata standards that enable self-service analytics, governance, and AI readiness
• Partner with BI and Analytics to ensure domain models are clearly documented and aligned to business language
• Collaborate with Data Science to ensure model inputs, features, and outputs are traceable, explainable, and reusable
• Design and evolve security and access-control models for Apache Iceberg, including table-, column-, and row-level controls
• Partner with Security and Platform teams to embed policy enforcement directly into data access paths
• Drive metadata-driven authorization patterns that scale across tools and user groups
• Ensure privacy, compliance, and regulatory requirements are incorporated into platform design
• Balance strong security guarantees with usability to support safe self-service
• Build and maintain automation for compaction, retention, lifecycle management, and cost controls
• Establish observability standards that connect pipeline health, data quality, and reliability metrics
• Provide architectural oversight during critical incidents and drive long-term 'Keep the Lights On' (KTLO) reduction
• Recommend tooling and process improvements based on industry standards and operational experience
• Align technical work with business priorities by understanding how data supports onX products and customer outcomes
• Communicate complex technical concepts clearly to engineers, product partners, and leadership
• Lead and participate in architecture and design reviews, setting a high bar for technical rigor
• Foster strong cross-team collaboration across Data Engineering, Platform, Security, Analytics, and Data Science
• Mentor senior and mid-level engineers, raising the technical bar across the team

Requirements:

• Bachelor's degree in Computer Science or equivalent experience
• Deep industry experience (typically 12+ years) building and operating large-scale data systems
• Deep expertise in distributed data systems and data architecture
• Strong experience with Apache Iceberg and similar table formats (Delta Lake, Hudi)
• Proven experience designing secure and governed data platforms
• Expertise in Python, SQL, and orchestration patterns (e.g., Airflow)
• Experience working with data ecosystems, including metadata, catalog, or governance tooling
• Strong written and verbal communication skills
• Permanent U.S. work authorization
• Deep experience in at least one major cloud environment (GCP, AWS, or Azure)
• Familiarity with cloud-native data services such as query engines, stream/batch processing systems, and object storage–based lakehouses
• Comfort with infrastructure-as-code and automated platform management
