Description

  • Take ownership of cloud security across GCP and Azure from design through day-to-day execution, partnering with infrastructure, platform, data, and application teams.
  • Run data security and vulnerability management programs, including DLP, sensitive data discovery, prioritization, remediation tracking, and reporting.
  • Build and maintain security automation using Infrastructure as Code (Terraform) and CI/CD pipelines to enforce consistent, auditable security controls.
  • Own and tune cloud security posture tooling (Wiz or similar), reduce noise, investigate real risks, and drive remediation efforts.
  • Regularly review cloud configurations, identify and remediate gaps before they become incidents, and maintain infrastructure security controls tied to PCI and SOC 1/2 compliance.
  • Write and maintain clear cloud security standards, runbooks, and playbooks that are practical and actionable for engineering teams.
  • Develop detections and response playbooks in Chronicle SIEM and act as a senior escalation point during cloud security incidents, helping teams triage, contain, and resolve issues.
  • Mentor and raise the skill level of other engineers, and lead or independently drive end-to-end security projects without creating silos.

Requirements

  • Minimum 8 years related experience with a Bachelor’s degree, or 6 years with a Master’s degree.
  • Hands-on production cloud/infrastructure security experience in both Google Cloud Platform (GCP) and Microsoft Azure.
  • Experience with security assessments, security design reviews, or threat modeling.
  • Strong understanding of cloud fundamentals including IAM, networking, logging, monitoring, and encryption and how failures occur in cloud environments.
  • Proven experience building security automation with Python for integrations and automation tasks.
  • Practical experience with Terraform and security-as-code, including integrating security checks into CI/CD pipelines.
  • Hands-on experience with Wiz or similar CNAPP tools and the ability to distinguish real risk from noise and drive remediation.
  • Experience writing or tuning detections in Chronicle SIEM and understanding how cloud threats appear in logs.
  • Background in vulnerability management and remediation tracking, plus familiarity with penetration testing and using findings to improve systems.

Benefits

  • Salary range $138,000–$190,000 annually plus bonus and generous benefits.
  • Flexible time off and paid parental leave.
  • Comprehensive health coverage and other wellness benefits.
  • Ability to work remotely within the United States (remote-friendly).
