Sr. Information Security Engineer- Platform Engineer (Lucknow)

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
