Sr. Infrastructure Security Engineer

How you'll make an impact

• Own cloud security across Google Cloud Platform (GCP) and Microsoft Azure, driving initiatives from design through execution
• Reduce real risk by operationalizing CNAPP tooling like Wiz - cutting noise, prioritizing high-impact issues, and ensuring remediation lands
• Embed security into infrastructure using Terraform and CI/CD, making controls scalable, consistent, and developer-friendly
• Lead vulnerability management end-to-end, from triage to remediation tracking, partnering with engineering to ship fixes quickly
• Strengthen data and endpoint security (DLP, EDR, identity, device posture) and reduce exposure across cloud environments
• Improve detection and response by building and tuning detections in Google Chronicle and supporting incident response
• Proactively identify and fix cloud misconfigurations (IAM, networking, firewalls, encryption) before they become incidents
• Define practical security standards and runbooks that engineers can easily adopt
• Act as a senior escalation point during security incidents, driving effective triage and resolution
• Leverage AI tools responsibly to accelerate code review, triage, and security analysis while maintaining strong security guardrails
• Mentor engineers and raise the overall security bar through collaboration and clear risk communication
