As a senior Cyber Threat Hunter in the Cyber Security Operations team, you will develop behavior-based detection capabilities that identify adversary activity before incidents occur by leveraging enterprise telemetry and AI-enabled workflows. Your day-to-day responsibilities include translating attacker techniques into durable detection logic using Python for data analysis and machine learning to enhance precision and operational actionability. You will collaborate closely with security operations, incident response, and detection engineering teams in a cloud environment to ensure detections are validated and integrated effectively. The role requires expertise in digital forensics, malware analysis, and statistical modeling, along with proficiency in Python, Git, CI/CD pipelines, and AI-assisted development tools. Experience with Google SecOps or Chronicle is beneficial for working on large-scale enterprise telemetry and signal engineering tasks.
