- Implement and optimize both batch and real-time streaming data processing systems to support detection and prevention workflows
- Ensure data quality, reliability, and availability across all security data platforms and services
- Build and maintain data storage solutions optimized for high-volume security telemetry and fast query performance
- Collaborate with security researchers and product teams to understand data requirements and deliver reliable data services
- Monitor and troubleshoot data pipeline performance, implementing automated alerting and recovery systems
- Establish data governance processes and implement security controls for sensitive threat data
- Optimize data infrastructure costs while maintaining performance and reliability standards
Required Skills and Qualifications:
5+ years of experience in data engineering, with a focus on large-scale data systems and operations
Strong proficiency in Python, SQL, and distributed data processing frameworks (Spark, Kafka, etc.)
Proven experience building and maintaining production data pipelines that handle high-volume, high-velocity data
Expertise with cloud data platforms (AWS, GCP, or Azure) and infrastructure-as-code practices
Experience with data storage solutions, including data lakes, warehouses, and more
Strong understanding of data quality, monitoring, and operational best practices
Familiarity with containerization (Docker, Kubernetes) and CI/CD practices
Cybersecurity domain knowledge
Bonus Skills and Qualifications:
- Experience with security data formats and sources (SIEM, EDR, network logs, threat feeds)
- Familiarity with Elastic/OpenSearch and other data platforms
- Background in stream processing frameworks (Kafka Streams, Apache Flink, etc.)
- Experience with modern data architecture patterns
- Knowledge of compliance requirements for security data handling
