Work You'll Do
As a Security Data Engineer, on the Enterprise Security team, you will be responsible for: o Design, write, and deploy high-fidelity detection rules using SQL, Sigma, YARA-L, or Python targeting network-based attack techniques (e.g., C2 beaconing, data exfiltration, and lateral movement).
o Continuously tune network detections to reduce false-positive rates while maintaining a high signal-to-noise ratio.
o Identify telemetry required to support network monitoring, threat hunting, incident response, and custom detection engineering.
o Map detection requirements to underlying data sources and identify visibility gaps across hybrid cloud and on-premises environments
o Design and maintain pipelines that ingest security telemetry from network, endpoint, identity, cloud, application, OT, and security infrastructure.
o Ensure telemetry is delivered reliably to SIEM, data lake, analytics, and detection platforms; troubleshoot ingestion, parsing, latency, and data-quality issues.
o Evaluate whether packet, flow, session, DNS, proxy, authentication, endpoint, and application telemetry is sufficient for specific detection requirements.
o Support custom detection development through data discovery, enrichment, normalization, and validation.
o Identify opportunities to move detections from low-level indicators toward higher-level behavioral and tradecraft-based detection using the Detection Stack.
o Work with network engineering teams to evaluate technologies such as network sensors, NetFlow/IPFIX, DNS telemetry, proxy telemetry, firewall logs, IDS/IPS, packet capture, Zeek/network metadata, and NDR platforms.
o Establish telemetry health metrics, dashboards, and automated checks for missing, delayed, or malformed data.
o Assess network visibility across data centers, cloud environments, remote networks, and segmented environments.
o Optimize telemetry architectures and ingestion pipelines for performance, scalability, reliability, and cost
