Role overview
Join Notion’s Data Platform team as we build out the data infrastructure for Notion's next phase of large enterprise customers and novel agentic data use cases. You’ll help design and build the core data platform that powers Notion’s AI, analytics, and search while meeting stringent security, privacy, and compliance requirements. This role focuses on the data platform layer (storage, compute, pipelines, governance) and partners closely with Infrastructure, Security, Search Platform, AI, and Data Engineering.
Responsibilities
- Design and evolve the data lakehouse Build and operate core lakehouse components (e.g., Iceberg/Hudi/Delta tables, catalogs, schema management) that serve as the source of truth for analytics, AI, and search.
- Own critical data pipelines and services Design, implement, and harden batch and streaming pipelines (Spark, Kafka, etc.) that move and transform data reliably across regions.
- Advance EKM and encryption-by-design Work with Security and platform teams to integrate Enterprise Key Management (EKM) into data workflows, including file- and record-level encryption and safe key handling in Spark and storage systems.
- Improve data access, auditability, and residency Build primitives for fine-grained access control, auditing, and data residency so customers can see who accessed what, where, and under which guarantees.
- Drive reliability and observability Raise the operational bar for our data stack: improve on-call experience, debugging, and alerting for data jobs and services.
- Optimize large-scale performance and cost Tackle performance and cost challenges across Kafka, Spark, and storage for very large workspaces (20k+ users, multi-cell deployments)
- Shape the platform roadmap Empower product and infrastructure engineering teams reliable, scalable data infrastructure to enable novel large volume, agentic use cases.
- Experience: 2+ years building and operating data platforms or large-scale infrastructure for SaaS or similar environments.
- Programming: Strong skills in at least one of Python, Scala, or Typescript; comfortable working with SQL for analytics and data modeling.
- Distributed data systems: Hands-on experience with Spark or similar distributed processing systems, including debugging and performance tuning.
- Streaming & ingestion: Experience with Kafka or equivalent streaming systems; familiarity with CDC/ingestion patterns (e.g., Debezium, Fivetran, custom connectors).
- Lakehouse / storage: Experience with data lakes and table formats (Iceberg, Hudi, or Delta) and/or data catalogs and schema evolution.
- Operations: Comfortable owning services and pipelines in production, including on-call, incident response, and reliability improvements.
- Experience working in an applied data platform setting, such as Trust and Safety, and/or directly with enterprise customers or on features like data residency, analytics product, EKM, or compliance-driven auditing.
- Security & governance: Practical understanding of access control, encryption at rest/in transit, and auditing as they apply to data platforms. Prior work on Databricks, Unity Catalog, Lake Formation, or similar catalog/governance systems.
- Experience designing or improving observability for data platforms (e.g., Honeycomb, OpenTelemetry, metrics/trace-heavy debugging).
