Qualifications

• Relevant experience in threat detection, security operations, or threat hunting.
• Hands on, day to day experience with SIEM, EDR, and NDR platforms, including writing and tuning detection logic.
• Working knowledge of a scripting language for automation, at the level needed to build useful internal tooling.
• Demonstrated ability to investigate suspicious activity end to end: read the logs, form a conclusion, and communicate it clearly.
• Familiarity with the MITRE ATT&CK framework and the ability to reason about adversary tradecraft rather than only indicators.
• Solid understanding of operating system internals, networking, and authentication as they appear in security telemetry.
• University degree in Engineering, MIS, CIS, or related discipline; or equivalent years of experience

Responsibilities

• Detection Engineering - Design, build, test, and maintain detection content across SIEM, EDR, and NDR platforms, and document the intent, data source, and expected behavior of each detection
• Detection Tuning and Health - Own false positive rates, alert volume, and rule health for assigned detection areas, including retiring logic that no longer earns its place
• Detection Coverage - Map detection coverage to the MITRE ATT&CK framework, identify gaps, and propose the telemetry or logic needed to close them
• Threat Intelligence Integration - Convert threat intelligence reporting into prioritized detection and hunting work, so coverage follows the adversaries and techniques most relevant to the sector rather than whatever arrived most recently
• Proactive Threat Hunting - Develop and execute focused hunts to discover threats that evade existing controls, and promote successful hunt outcomes into durable production detections
• Red Team Gap Remediation - Take ownership of detection gaps reported through red team and purple team exercises; track each gap to closure, build or amend the detection, and validate that the exercise activity is caught on retest
• Log Source Health - Validate the health and completeness of security log sources, detect collection failures and silent feeds, and onboard or update SIEM log sources in a timely manner
• Automation and Tooling - Apply a developer and problem-solving mindset to the work, using scripting to build internal tooling, process and normalize data, and remove repetitive manual effort wherever it appears
