THE ROLE Rogo is hiring a Staff Security Engineer to lead the design and implementation of cloud security architecture across AWS and GCP. This is a deeply hands-on role for an engineer who has built and operated secure cloud platforms at scale and prefers solving security problems through code, systems design, and automation rather than policy alone. You will own the technical direction of cloud security at Rogo: designing secure primitives, authoring Terraform at scale, shaping identity and network architecture, and embedding security into the core platform. You will operate as a senior technical leader while remaining highly tactical, writing production code, reviewing infrastructure changes, and unblocking teams with pragmatic security solutions. WHAT YOU WILL OWN - Architect and implement cloud security foundations across AWS and GCP, including account/project structure, IAM models, network segmentation, and secure service-to-service communication. - Own and author Terraform-based security architecture, including: - Reusable, opinionated Terraform modules for IAM, networking, logging, and encryption - Policy enforcement and guardrails that prevent insecure infrastructure from being deployed - Secure defaults embedded directly into infrastructure primitives - Design and operate cloud identity systems at scale, including workload identity, service accounts, role assumption, and cross-cloud access patterns. - Lead the security design of cloud networking, including VPC architecture, private connectivity, egress control, firewalling, and isolation boundaries. - Build and maintain security automation across CI/CD and cloud environments, eliminating manual processes and reducing operational risk. - Own Kubernetes and container security for production workloads (GKE/EKS), including cluster hardening, RBAC, workload identity, image security, and runtime controls. - Define and implement logging, monitoring, and detection pipelines that provide high-signal visibility into cloud security posture and incidents. - Perform threat modeling and architectural reviews for new infrastructure and platform changes, driving security decisions with technical authority. - Act as a technical multiplier: reviewing critical infrastructure changes, mentoring engineers, and raising the overall security bar across the organization. GREAT CANDIDATES OFTEN: - Have built cloud security platforms or foundational infrastructure in AWS and GCP, not just consumed managed services. - Are deeply fluent in Terraform, including large-scale state management, module design, and safe rollout strategies. - Think in terms of secure systems and primitives, not one-off controls or point solutions. - Have strong opinions on cloud IAM and networking design, informed by real-world failures and incident response. - Are comfortable operating in ambiguous environments and defining long-term technical direction. - Prefer automation, code, and guardrails over documentation and manual review. - Can influence architecture through technical depth rather than organizational authority.
