• Set architectural standards for CoreWeave's lakehouse, including data organization, schemas, metadata, governance, and serving patterns.
• Design scalable frameworks for data quality, lineage, observability, access control, and policy enforcement.
• Lead the architecture of complex, cross-domain data systems spanning operational, financial, product, people, and infrastructure data.
• Establish durable data contracts, system boundaries, and reusable engineering patterns across teams.
• Identify and resolve systemic performance, reliability, and scalability constraints across the data ecosystem.
• Lead architecture reviews for high-impact initiatives and ensure alignment with the broader platform strategy.
• Evaluate and standardize core data technologies across processing, orchestration, cataloging, modeling, and metadata management.
• Mentor senior engineers and raise the quality of system design and technical decision-making across the organization.

Who You Are:

• 10+ years of experience in data engineering, software engineering, distributed systems, or data architecture roles.
• Demonstrated experience setting technical direction for data systems spanning multiple teams, business domains, or platforms.
• Deep expertise in enterprise analytical modeling, including dimensional, Data Vault, semantic modeling, and governed metrics.
• Experience designing and operating large-scale lakehouse or streamhouse architectures using technologies such as Apache Iceberg, Delta Lake, Apache Hudi, Apache Paimon, or Apache Fluss.
• Advanced knowledge of distributed OLAP, query, processing, and ingestion systems such as StarRocks, ClickHouse, Trino, Spark, Flink, or Kafka.
• Expert-level SQL and strong programming expertise in Python, Scala, Java, or Rust, with experience building production-grade data systems.
• Demonstrated experience implementing governance capabilities such as lineage, profiling, metadata management, data quality controls, access policies, or auditability.
• Demonstrated ability to independently turn ambiguous problem statements into clear technical direction and execution plans.
• Track record of leading cross-cutting architecture and establishing standards adopted across multiple engineering teams.

Preferred:

• Experience designing data systems that support compliance programs such as SOX, GDPR, MNPI, and PII controls.
• Experience operating event-driven architectures using Kafka, AutoMQ, Pulsar, or similar streaming platforms.
• Experience running data-intensive workloads on Kubernetes.
• Experience in high-growth cloud, infrastructure, or distributed-systems organizations.
