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 Collaboration & Communication Communicate findings, risks, and recommendations clearly to both technical and non-technical stakeholders Translate technical observations into business-relevant impact Demonstrate strong active listening and the ability to incorporate differing perspectives Maintain a collaborative, solutions-oriented approach while providing clear recommendations and direction On-Call & Operational Support Participate in on-call rotation for after-hours response Respond to security incidents and production-impacting issues in a timely and structured manner Education and Experience: Bachelor’s degree in Computer Science, Computer Engineering, Information Technology or related field. Minimum five (8) years of experience in information security, network security or infrastructure security.
