The Department: Platform Security

The Platform Security team secures Gemini’s infrastructure through service hardening and by developing and supporting a suite of foundational tools. We provide secure-by-default infrastructure, consumable security services, and expert consultation to engineering teams for secure cloud and non-cloud infrastructure.

The Role: Staff Platform Security Engineer (Cloud/K8S)

The Platform Security team builds and delivers zero-trust foundations and paved paths so every Gemini team can ship safely on supported cloud platforms. As a Staff Cloud and Kubernetes Security Engineer, you will partner closely with engineering teams to enable rapid, secure delivery while maintaining zero standing privilege and least-privilege access models.

You'll design and build security platforms that scale across our engineering organization. This role requires deep technical expertise in cloud security, strong Terraform proficiency, and strong software development skills to build production services. This is a hands-on engineering role where you'll write production code daily, not just infrastructure-as-code.

Design and implement security controls for AWS and Kubernetes environments using infrastructure-as-code

Create reusable libraries, frameworks, and platforms that enable secure-by-default patterns

Partner with engineering teams on architecture decisions and provide security consultation

Participate in on-call rotation for critical security incidents and infrastructure issues

Minimum Qualifications

Strong software development skills in Python or Go with experience building production services

Strong experience securing AWS environments including IAM, VPC, KMS, and native security services

Deep Terraform expertise including module development, CI/CD gates, policy testing, remote state management, and zero-downtime deployments

Proven expertise with Kubernetes security including admission controls, RBAC, network policies, and runtime protection

Experience with distributed systems, cloud-native architectures, and SRE principles

Demonstrated ability to build, deploy, and maintain security tools and services in production

Preferred Qualifications

Experience with GCP security services and multi-cloud environments including Azure

Knowledge of policy-as-code tools such as Open Policy Agent, Sentinel, or similar

Experience with container security scanning, image signing, and supply chain security

Background in incident response for cloud and container environments

Experience with service mesh technologies and zero-trust networking

Contributions to open source security tools or cloud security communities
