Develop automation for alert enrichment, investigation, and incident response.
Perform root-cause analysis and drive remediation following security incidents.
Work closely with Engineering, DevOps, Platform, and Security teams to strengthen our overall security posture.

Desired Candidate Profile:

5–7 years of experience in Security Operations, Detection Engineering, Incident Response, Threat Hunting, or Security Engineering.
