• Position Summary
• The Principal Threat Detection Engineer serves as a senior, highly technical individual contributor responsible for the design, implementation, and continuous evolution of advanced threat detection capabilities across the enterprise.

This role owns the development and optimization of detection logic leveraging Microsoft Security tooling, CrowdStrike, Splunk Cloud, Cribl, and related SOC platforms to identify sophisticated adversary activity spanning endpoint, network, and cloud environments. A core focus of the role is proactive threat hunting and the identification of behavioral indicators that improve visibility into novel and emerging attack techniques. In this capacity, the Principal Threat Detection Engineer leads detection engineering strategy and execution, building, tuning, and automating high‑fidelity alerts using SIEM and analytics platforms such as Splunk Cloud, Microsoft Sentinel, and Cribl. The role applies deep knowledge of query languages (including KQL) and custom detection logic to reduce noise, improve precision, and increase analyst efficiency. Detection capabilities are continuously iterated based on adversary tradecraft, environmental changes, and lessons learned from active investigations and simulations. The role operates at the intersection of offensive and defensive security, collaborating closely with threat hunting, incident response, and purple team partners to translate adversary emulation and penetration testing findings into actionable detection improvements aligned to the

MITRE ATT&CK

framework. The position integrates threat intelligence and supports active incident investigations by providing insight into attacker behavior and detection blind spots. Through continuous innovation and a strong understanding of regulatory and compliance considerations (e.g., PCI-DSS, HIPAA, NIST, ISO 27001), the Principal Threat Detection Engineer strengthens the organization's overall detection maturity and cyber resilience.
