EYSIEM Security Engineer
About this role
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.
Your Key Responsibilities
- Support the deployment, configuration, and management of SIEM solutions across On-Premises, Hybrid, and Cloud Based environments following EY standards.
- Assist in the deployment and management of Azure Monitor Agent (AMA) and Azure ARC for connected machines.
- Support data pipeline operations: onboarding new log sources using out-of-the-box connectors, Syslog/CEF ingestion, and stream processing tools.
- 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.
- Develop professional skills through collaboration with senior engineers and architects.
Skills and Attributes for Success
- Good understanding of SIEM platforms and their role within enterprise security operations.
- Foundational knowledge of Microsoft Sentinel: data connectors, Analytic Rules, Workbooks, and Watchlists.
- Familiarity with data pipeline concepts: log normalization, CEF/Syslog, and log ingestion strategies.
- Basic awareness of SOAR concepts (Logic Apps or equivalent) and automation workflows.
- Understanding of compliance and vulnerability management frameworks and how they relate to security monitoring.
- Effective communicator in English (written and verbal) — able to convey technical concepts clearly.
- Eager to learn and improve; continuous-improvement mindset with an interest in automation.
To Qualify for the Role, You Must Have
- 3–5 years of experience in IT Security or a related technical field, with growing exposure to SIEM engineering.
- Hands-on experience with Microsoft Sentinel or a comparable SIEM platform
- Basic proficiency with KQL or similar query languages for log investigation and rule creation.
- Foundational knowledge of cloud environments: Azure (primary), with awareness of AWS and/or GCP.
- Basic scripting skills in Python, PowerShell, or Bash for task automation.
- Understanding of security event sources: Windows Event Logs, Syslog, firewalls, and endpoint agents.
Ideally, You Will Also Have
- Bachelor’s degree in computer science, Engineering, IT, Mathematics, or equivalent work experience.
- Cloud or security certification: Microsoft SC-200 / AZ-500, CompTIA Security+, Splunk Core Certified User, or equivalent.
- Exposure to SOAR platforms (Logic Apps, Cortex XSOAR, or equivalent).
- Familiarity with the MITRE ATT&CK framework and its use in detection engineering.
- Experience working in a SOC or security monitoring environment.
