• Triage escalated alerts to determine whether a security incident is occurring or may occur imminently.
• Respond to security incidents, whether as an incident commander or as an incident responder
• Make us more efficient through building tools and automations that eliminate repetitive processes
• Help us improve our overall security posture through post-incident reviews, tabletop and purple team exercises, and process/runbook improvements.
• Participate in a light on-call rotation.

 

Who You Are:

• You have at least 5 years of experience in security incident response, threat hunting, security operations, cloud security, or other operational security domains.
• You’ve worked with at least one public cloud platform (AWS, GCP, or Azure) and cloud-native technologies like Kubernetes, Docker, or Terraform.

• You’ve used a wide range of technologies and datasets to detect threats in cloud and enterprise environments
