Software Engineer, Data Platform
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
- check_circle 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.
- check_circle 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.
- check_circle 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.
- check_circle 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.
- check_circle Drive reliability and observability Raise the operational bar for our data stack: improve on-call experience, debugging, and alerting for data jobs and services.
- check_circle 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)
- check_circle Shape the platform roadmap Empower product and infrastructure engineering teams reliable, scalable data infrastructure to enable novel large volume, agentic use cases.
- check_circle Experience: 2+ years building and operating data platforms or large-scale infrastructure for SaaS or similar environments.
- check_circle Programming: Strong skills in at least one of Python, Scala, or Typescript; comfortable working with SQL for analytics and data modeling.
- check_circle Distributed data systems: Hands-on experience with Spark or similar distributed processing systems, including debugging and performance tuning.
- check_circle Streaming & ingestion: Experience with Kafka or equivalent streaming systems; familiarity with CDC/ingestion patterns (e.g., Debezium, Fivetran, custom connectors).
- check_circle Lakehouse / storage: Experience with data lakes and table formats (Iceberg, Hudi, or Delta) and/or data catalogs and schema evolution.
- check_circle Operations: Comfortable owning services and pipelines in production, including on-call, incident response, and reliability improvements.
- check_circle 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.
- check_circle 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.
- check_circle Experience designing or improving observability for data platforms (e.g., Honeycomb, OpenTelemetry, metrics/trace-heavy debugging).
