Data ArchitectLocation: Menlo Park, CA (Remote)Note: Education M.S./Ph.D. in Computer Science (Formal Methods/Logic) or Computational Mathematics.Role Overview: We are seeking a visionary to architect a Self-Healing, Autonomous Data Fabric. You will replace legacy ETL with a "nervous system" where metadata is active, governance is computational, and data sharing is zero-copy.Mandatory Skills:Active Metadata: Experience building closed-loop automation (e.g., metadata-triggered autonomous schema repair).Semantic Engineering: Mastery of RDF, OWL, and SHACL for ontology-first modeling and SPARQL reasoning.Production-level Open Policy Agent (OPA)/ Policy-as-Code (Zero-Trust) for dynamic, context-aware access control.Other Technical Skills:Advanced Privacy: Implementation of Homomorphic Encryption (FHE) or SMPC for analytics on encrypted PII.Zero-Copy Architecture: Expertise in Delta Sharing for cross-cloud analytics without egress.Compute: Trino (GraalVM), StarRocks, DuckDB (WASM).Orchestration: Dagster, Airflow (Provider-level).Semantic Layer: Stardog, Apache Jena, GraphQL Federation.System Languages: Rust, Clojure, or Java.
