- Experience with PowerShell or Python, work in multi-account MSSP settings, and familiarity with Asia-Pacific threat actors are advantageous.
Responsibilities
- You will function as the technical account owner and main liaison for the security team.
- You will facilitate periodic security meetings to address notable events and strategic upgrades, while handling technical escalations.
- You will perform threat hunting based on intelligence and detection coverage gaps, converting threat indicators into usable detection logic.
- You will consistently monitor and calibrate detection rules to reduce false positives and uncover risks like Active Directory flaws or misconfigurations.
- You will guide major incident investigations by correlating telemetry, building timelines, and performing root-cause analysis.
