Platform Security Engineer, NZ

## About the role The Platform Security Engineer will own Partly's security posture while contributing to platform reliability, reporting to Platform Lead. This role combines infrastructure security with platform reliability - someone who can harden our systems while keeping them running.

Respond to enterprise customer security questionnaires. Maintain and communicate the risk register to engineering and leadership. - Harden our infrastructure. Implement principle of least privilege across the stack - PostgreSQL roles for applications, Kubernetes RBAC refinement, ensuring applications only get the secrets they need. Drive network segmentation and zero-trust progress using Cilium network policies and Kyverno admission policies. Make production access read-only by default for developers. - Manage vulnerabilities systematically. Implement and operate our vulnerability scanning pipeline using Trivy, Renovate, and Falco. Own the vulnerability triage process - severity assessment, prioritization, tracking to resolution.
