Sr. Information Security Engineer- Platform Engineer

Essential Functions:

Platform Engineering & Optimization

• Configure, maintain, and optimize assigned security platforms across endpoint, network, web, and identity domains
• Continuously refine policies, detection logic, and configurations to improve signal quality, reduce false positives, and enhance visibility
• Apply platform capabilities to develop and improve detection coverage (e.g., IOA, behavioral detection)
• Ensure platform health, telemetry integrity, and effective coverage across environments
• Evaluate and implement enhancements that improve effectiveness of existing tools before recommending new solutions

Alert Analysis & Investigation

• Analyze alerts and raw telemetry generated by security platforms and determine appropriate action based on context and risk
• Investigate suspicious activity using available data sources, including logs, network traffic, and endpoint behavior
• Apply independent judgment to distinguish between benign, anomalous, and malicious activity
• Perform triage and root cause analysis, escalating when broader coordination is required

• Contribute to incident response through multi-platform analysis and insight

Operational Support & Issue Resolution

• Troubleshoot and resolve issues related to security controls, including access disruptions, false positives, and policy conflicts
• Apply practical, risk-based decisions when adjusting controls to balance security and operational needs
• Collaborate with IT, engineering, and business teams to diagnose and resolve issues efficiently

Cross-Platform Contribution

• Develop working knowledge across multiple security domains to support team resiliency
• Serve as a secondary resource across platforms (endpoint, email, vulnerability, cloud)
• Collaborate with peers to ensure continuity of coverage and reduce single points of failure

Continuous Improvement

• Identify gaps in detection, visibility, and control effectiveness based on operational experience
• Improve detection quality, reduce noise, and enhance response effectiveness (MTTD/MTTR)
• Contribute to development of playbooks and processes, while remaining effective in situations where such guidance is incomplete
• Implement automation or scripting where appropriate to improve efficiency
