Staff Security Engineer Data Science Engineering

You will build and operate security-data pipelines across endpoint, identity, cloud, network, vulnerability, SaaS, and internal-platform telemetry. You will measure data quality, detect collection gaps, create behavioral and cross-source detections, support incident investigations, and prepare governed datasets for AI-assisted analysis.

Responsibilities

• Own the inventory of security-relevant data sources and document ownership, collection, freshness, coverage, and gaps.
• Build and operate idempotent batch and streaming collection pipelines from APIs, event streams, object stores, and internal systems.
• Monitor data freshness, volume, completeness, duplicates, schema drift, and cross-source consistency.
• Make pipeline failures visible and support backfill and replay.
• Build and evaluate behavioral baselines, anomaly detection, and cross-source correlations.
• Support major incidents with scoping, timelines, and pattern analysis.
• Prepare curated and documented datasets for AI-assisted analysis with audited access and provenance.
• Coordinate access, schemas, and collection cadences with source-system owners.

Requirements

• 8+ years of experience in data engineering, data science, detection engineering, security analytics, or a related technical field, including significant security-data work.
• Experience building and operating security data pipelines, including API and event-source collection, idempotent loads, partitioning, backfill, replay, and schema evolution.
• Experience with a cloud warehouse and streaming system, such as BigQuery and Kafka.
• Knowledge of security telemetry across identity, endpoint, cloud, network, vulnerability, and SaaS audit logs.
• Ability to apply statistical or machine-learning methods to security analysis and translate results into usable detections.
• Ability to communicate coverage gaps and uncertain findings clearly.
