This role centers on the security of the cloud foundation, data platform, AI/ML infrastructure, and internal developer platform that the product depends on. This is a deeply technical, infrastructure-focused role. You'll work closely with Platform Engineering, DevOps, Data Engineering, and AI/MLOps teams to ensure that the systems, pipelines, and environments underpinning our product are designed, built, and operated securely. What You'll Do... Cloud Infrastructure Security * Own the end-to-end security infrastructure architecture of our Azure environment, including landing zone design, management group and subscription structure, network topology, and resource governance. * Enforce and continuously improve guardrails using Azure Policy, Cloud security posture management (CSPM), and infrastructure-as-code (IaC) security scanning (Checkov, tfsec, or equivalent). * Manage and mature the Azure network security model: hub-and-spoke topology, NSG and Azure Firewall rule governance, Private Endpoints, and DDoS protection controls. * Lead cloud infrastructure security posture reviews, drive down misconfigurations, and own the organization's Secure Score improvement roadmap. * Maintain and harden Azure landing zones, ensuring new workloads are provisioned into a secure-by-default environment. Identity, Access, and Secrets Management * Drive the organization's cloud identity and access management strategy, including Entra ID tenant configuration, Privileged Identity Management (PIM), Conditional Access policies, and workload identity (managed identities, federated credentials, service principals). * Enforce least-privilege IAM across all Azure subscriptions and resources; conduct regular access reviews and entitlement hygiene campaigns. * Architect and operate the enterprise secrets management program using Azure Key Vault with HSM-backed keys, including key rotation automation, certificate lifecycle management, and developer-facing secrets injection patterns. * Define and enforce policies for human and non-human identities across CI/CD systems, internal tooling, and AI/ML workloads. Kubernetes and Container Platform Security * Secure the Azure Kubernetes Service (AKS) platform: cluster hardening, node pool configuration, admission control (OPA/Gatekeeper, Kyverno), runtime security, and network policy enforcement. * Own container security standards: base image governance, image signing and provenance (Notary, Cosign), container registry security (Azure Container Registry), and vulnerability scanning integration in the build pipeline. * Maintain and improve Pod Security Standards, workload identity binding (Azure Workload Identity), and namespace-level security isolation. * Collaborate with Platform Engineering on the internal developer platform (IDP) to ensure that developer self-service pathways are built with security guardrails as first-class controls. AI and Data Platform Security * Secure the data and AI/ML infrastructure layer. * Define and enforce data security controls including storage encryption (CMK), data classification enforcement, network isolation for data services, and access boundary policies between training, staging, and production AI environments. * Establish security controls for AI/ML pipelines: training data provenance and integrity, model artifact signing, inference endpoint hardening, and isolation of multi-tenant AI workloads. * Work with Data Engineering and MLOps teams to ensure AI infrastructure changes go through security review and that data access patterns are auditable and compliant. Detection, Response, and Vulnerability Management * Own the cloud-native detection and monitoring stack * Develop and maintain detection rules and analytic content tuned to cloud infrastructure and AI platform threats (e.g., credential abuse, lateral movement, data exfiltration from AI workloads). * Lead the infrastructure vulnerability management program: agent-based and agentless scanning across Azure VMs, AKS nodes, and container images; SLA-based remediation tracking; and patch compliance reporting. * Own cloud incident response runbooks for infrastructure-layer security events and serve as the technical lead for cloud-scoped security incidents. Security Automation and Platform Hardening * Build and maintain policy-as-code frameworks that enforce security standards across IaC templates (Terraform, Bicep) before resources are provisioned. * Develop internal security automation for drift detection, misconfiguration remediation, and continuous compliance validation against CIS Azure Foundations Benchmark and equivalent baselines. * Partner with DevOps and Platform Engineering to embed security gates into infrastructure CI/CD pipelines, ensuring that insecure infrastructure changes cannot reach production. * Maintain the platform security baseline documentation and runbooks, enabling the broader engineering organization to build a well-understood, secure foundation. ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [The Private AI Platform: Why Agentic Apps Need a Private Application Platform](https://www.wearedevelopers.com/videos/100162-the-private-ai-platform-why-agentic-apps-need-a-private-application-platform) - [Back(end) to the Future: Embracing the continuous Evolution of Infrastructure and Code](https://www.wearedevelopers.com/videos/440-back-end-to-the-future-embracing-the-continuous-evolution-of-infrastructure-and-code) - [Get started with securing your cloud-native Java microservices applications](https://www.wearedevelopers.com/videos/123-get-started-with-securing-your-cloud-native-java-microservices-applications) - [The New AI Security Stack: Observe, Detect, Protect](https://www.wearedevelopers.com/videos/100302-the-new-ai-security-stack-observe-detect-protect) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Stephan Gillich - Bringing AI Everywhere](https://www.wearedevelopers.com/magazine/489-stephan-gillich-bringing-ai-everywhere) - [Got AI ideas but no money?
