The primary responsibilities of the Security Infrastructure Engineer Sentinel:

Functional Responsibilities:

Data Ingestion and Normalization Pipeline Management: Architect and maintain the ingestion of telemetry from multi-cloud (GCP, AWS, Azure) and on-premises environments using Bind Plane Forwarders, Cloud-to-Cloud (C2C) connectors, and Webhooks.

Parser Development: Design, build, and troubleshoot custom parsers (CBN) to ensure non-standard log sources are correctly normalized into the Unified Data Model (UDM).

Data Health Monitoring: Build dashboards to monitor ingestion rates, latency, and data drops to ensure the SIEM is always receiving high-quality, actionable data.

SOAR & Automation Engineering

Playbook Development: Design and code automated incident response playbooks in Sentinel SOAR using Python and visual builders.

Connector Engineering: Build and maintain API integrations between Sentinel SOAR and third-party tools (Firewalls, EDR, IAM, Ticketing systems).

Workflow Optimization: Automate repetitive manual tasks such as artifact enrichment, evidence gathering, and initial containment actions.

Case Management Configuration: Tailoring the SOAR environment to fit the SOC s operational needs, including custom fields, stages, and SLA tracking.

Platform Administration and Optimization

System Health Monitoring: Monitoring the ingestion health to ensure no data is dropped and that latency stays within acceptable limits.

Access Control: Managing Role-Based Access Control (RBAC) to ensure analysts have the correct level of access to sensitive data.

Threat Intel Ingestion: Managing the integration of Mandiant, Virus Total, and other third-party threat intelligence feeds to ensure detections are always up to date with the latest global threats.

Collaboration with SOC Team

Feedback Loops: Collaborating with Tier 1 and Tier 2 analysts to tune YARA-L rules based on real-world alert performance and noise levels.

Requirements Gathering: Interviewing incident responders to understand their manual workflows, then translating those into Sentinel SOAR playbooks.

Training & Enablement: Conducting knowledge transfer sessions on how to use UDM Search and the MS Sentinel interface to speed up investigations.

Alignment with Infrastructure Team

Data Ingestion Strategy: Working with GCP/AWS/Azure Architects to ensure that Cloud Logging and Pub/Sub are configured correctly for seamless export to Google SecOps platform.

Agent Deployment: Coordinating with IT Infrastructure teams to deploy and maintain Bind Plane Forwarders on on-premises servers and virtual machines.

Troubleshooting: Collaborating with Network Engineers to resolve connectivity issues or firewall blocks that prevent telemetry from reaching the Google SecOps platform.

Desired Candidate Profile

Academic & Professional Qualifications:

Bachelor s degree in computer science, IT, Cybersecurity, or equivalent.

Frameworks: MITRE ATT&CK, NIST Cybersecurity Framework.

Tools: Git (Version Control), Terraform (Infrastructure as Code), Docker/Kubernetes (Containerization).

Data Standards: Deep knowledge of JSON, Protobuf, and Regex for log parsing and normalization.

Soft Skills:

Strong analytical thinking and problem-solving capability.

Excellent communication skills, able to explain technical findings to non-technical stakeholders.

Ability to work independently, manage multiple priorities, and meet deadlines.

Attention to detail and a structured, documentation-driven mindset.
