As a Senior SIEM Engineer, you will
Own and improve end-to-end log ingestion into Google SecOps (formerly Chronicle)—from source onboarding through reliable shipment—so downstream teams can power search, alerting, enrichment, and investigations.
Design and deliver scalable improvements to ingestion pipelines, integrations, and data validation, including feed health signals, shipment validations, and other meta-attributes that ensure end-to-end feed reliability.
Partner with and build strong working relationships across Threat Management Engineering, Threat Detection & Operations, Cyber Threat Intelligence, and CSIRT to deliver high-quality, backward-compatible changes to large-volume, high-criticality data feeds and SecOps integrations.
Lead troubleshooting and root-cause analysis across log pipelines and SIEM integrations (including other SIEM platforms) as part of a shared 24/7 on-call rotation; implement preventative mechanisms through monitoring, runbooks, and automation.
Build and enhance ingestion integrations and operational tooling using Python and regular expressions for parsing, validation, transformations, and schema evolution across standard and non-standard formats (e.g., JSON, Syslog, CEF, CSV/TSV).
Develop monitoring and alerting aligned to platform SLOs/SLAs, improving completeness, timeliness, and quality while reducing incident recurrence and MTTR.
Collaborate across teams to prioritize work, unblock partners, and continuously improve telemetry quality and platform performance.
In this role, you are a technical contributor responsible for designing, building, and operating reliable log ingestion capabilities that enable the core cybersecurity mission at Target. You bring strong troubleshooting and systems thinking, developing deep understanding of the platform’s architecture, interfaces, and failure modes to drive scalable improvements across ingestion pipelines, integrations, feed health, and shipment validation. You lead investigations from signal to root cause, communicate clearly during incidents, and follow through with durable preventative fixes via observability, runbooks, and automation. You take broad end-to-end ownership—raising operational readiness so the platform can rapidly pivot to meet shifting cybersecurity landscape, priorities, and incident demands. You consistently produce high-quality code and operational changes, and you collaborate across teams to align on standards, unblock delivery, and continuously improve telemetry quality and platform performance.
