• Review, monitor, and evaluate SOC alerts and investigation outputs based on predefined scenarios and criteria.
• Distinguish true positives from false positives by validating investigative evidence and alert context.
• Perform end-to-end security investigations when required, including log analysis, entity pivoting, timeline reconstruction, and evidence correlation.
• Assess the correctness, completeness, and quality of SOC investigations produced by automated or human workflows.
• Apply consistent investigative judgment while recognizing that multiple valid investigation paths may exist for the same alert.
• Make clear binary determinations (e.g., ACCEPT / PASS) while also producing detailed ground-truth investigations when required.
• Use Splunk extensively to pivot across logs, entities, and timelines, including reading and reasoning about SPL queries.
• Maintain clear and accurate documentation of investigative steps, assumptions, evidence, and conclusions.
• Collaborate with program leads and other expert annotators to uphold high-quality investigation and annotation standards.
• Mentor or support other analysts where applicable, particularly in long-term or lead annotator roles.

• Proven ability to evaluate SOC investigations and determine whether conclusions are valid, incomplete, or incorrect.
• Strong investigative judgment and comfort making decisive evaluations.
• Fluent English (written and spoken) with strong documentation and communication skills.

• Experience with Endpoint Detection & Response (EDR) tools such as CrowdStrike Falcon, Microsoft Defender for Endpoint, or SentinelOne.
• Experience analyzing cloud security logs and signals from AWS (CloudTrail, GuardDuty), Azure (Activity Log, Defender for Cloud), or GCP (Cloud Audit Logs).
