The role: As a Senior Cloud Security Engineer, you will act as a technical leader in safeguarding our core cloud infrastructure. You will take ownership of maintaining the highest standards of security controls for our critical systems within Google Cloud Platform (GCP). We're looking for someone who thrives in complex environments, can solve infrastructure security problems where no established patterns exist, and isn't afraid to get their hands dirty. You won't just advise; you will actively build, configure, and fix security controls. You'll leverage your expert understanding of cloud services, infrastructure-as-code, and container security to architect robust security measures and drive systemic improvements across the organization. What you’ll do: Architect and Lead GCP Security: Take end-to-end ownership of designing and implementing security architectures for our GCP infrastructure. You will look beyond immediate fixes to architect long-term, scalable solutions for networking, compute, storage, and GKE. Hands-on Remediation & Engineering: You don't just identify risks; you fix them. You will actively write code, create Pull Requests, and apply configurations to resolve security issues, harden infrastructure, and deploy tooling (e.g., EDR, Identity proxies) in production environments. Drive Systemic Risk Reduction: Identify repeating classes of vulnerabilities or systemic risks (e.g., data exfiltration paths) and drive organizational change to eliminate them, rather than just patching individual issues. Manage GCP Security Posture: Utilize GCP-native tools (e.g., Security Command Center, Cloud Armor, VPC Service Controls, IAM) to continuously monitor, assess, and improve the security posture of our cloud environment. Advanced Network & Container Security: Design complex network security controls and Kubernetes (GKE) hardening strategies, balancing strict security requirements with operational velocity. Mentorship and Technical Sparring: Act as a technical mentor and sparring partner to other engineers. You will elevate engineering standards by guiding colleagues on advanced security concepts and architecture. Automate Security Ope...
