Monitoring, Logging, and Incident Response - configure Cloud Audit Logs, SIEM exports, and custom alerts for critical security events; lead root-cause investigations, build detection logic, and develop runbooks for cloud-wide incidents.

Requirements :

5+ years driving security and compliance in dynamic, regulated environments- securing cloud-native platforms and hybrid infrastructures, with deep familiarity in fintech and portfolio-management standards, and best practices for supporting distributed, remote teams.

Deep expertise with GCP security (IAM, KMS, VPC Service Controls, Cloud Logging / Audit, WAF, SecOps) and Kubernetes application hardening.

Strong Infrastructure-as-Code skills (Terraform or equivalent) and GitOps experience (ArgoCD, Flux).
