• Design, engineer, and implement security detection initiatives under the cybersecurity team lead. • Develop new detection logic for SIEM (Microsoft Sentinel) and network security platforms (Cisco FirePower, IDS/IPS), incorporating AI-driven tooling where applicable. • Write and optimize KQL queries for Sentinel to improve detection fidelity and reduce false positives. • Tune detection sets to raise security-relevant events for triage and response teams. • Maintain version control of detection logic using Git and GitHub workflows for collaborative development and auditability. • Bridge the gap between network engineering and cybersecurity teams to advocate for secure network designs and maximize security device capabilities. • Conduct technical briefings to enhance team awareness of network architecture and detection strategies. • Collaborate with operations and management to recommend improvements to security posture and ensure compliance with industry and federal standards (e.g., NIST, CISA).
