Security Monitoring - SIEM Engineer

The Opportunity

Today's world is fueled by vast amounts of information, making data more valuable - and more vulnerable - than ever. As a SIEM Engineer at the Senior Analyst level within our Global Delivery Services (GDS) center in India, you will become a key contributor to the Security Technology Services (STS) group. You will support the engineering lifecycle - deployment, configuration, integration, and ongoing maintenance - of our Microsoft Sentinel-based SIEM platform and related security monitoring technologies across cloud and on-premises environments. This is a hands-on engineering role where you will grow your technical capabilities while contributing to how EY detects and responds to threats at enterprise scale. You will collaborate with Security Architects, Cloud Engineers, Security Operations, and SOC Analysts across time zones, supporting SIEM and security monitoring services under the guidance of senior engineers.

• Assist in building and maintaining Logic Apps and Azure Functions for automated response workflows.
• Support Azure RBAC management as it applies to Microsoft Sentinel and Log Analytics Workspaces.
• Assist with data transformation and optimization - normalization, parsing of raw logs, and basic tuning of ingestion volumes and retention policies.
• Support external cloud vendor log ingestion pipelines (AWS, GCP, Zscaler, etc.) under senior engineer guidance.
• Serve as a technical escalation point for SOC analysts on SIEM-related queries and investigations.
• Contribute to technical documentation: runbooks, configuration guides, and engineering standards.
