About the role

Key responsibilities & impact
  • You will own the security architecture, guardrails, and automation patterns, while partnering with platform and infrastructure teams on implementation.
  • Own and evolve Cloud Security Posture Management (CSPM) capabilities, including policies, guardrails, and automated remediation.
  • Engineer and maintain cloud network security controls, including network segmentation and isolation, cloud-native firewalls and security groups, Application Gateway / WAF configurations, and secure ingress and egress patterns.
  • Define and enforce security best practices for Kubernetes environments (AKS/EKS), including RBAC, network policies, workload isolation, and cluster hardening.
  • Partner with engineering teams on architecture reviews for new services, platforms, and major changes, helping teams design secure, compliant, and practical solutions.
  • Engineer and maintain identity and access security controls for cloud and production environments, including least privilege, workload identity, service principals, and conditional access.
  • Apply a security lens to FinOps, defining guardrails that balance cost optimization with security and compliance.
  • Develop tooling, automation, and self-service workflows that reduce manual effort and improve consistency across security programs.
  • Communicate complex security risks and technical recommendations clearly to engineering teams, leadership, and cross-functional stakeholders.
  • Mentor junior engineers and contribute to raising the overall security maturity of the organization.

Requirements

What you’ll need
  • 6+ years of experience in cloud security, security engineering, or cloud platform engineering roles.
  • Deep hands-on security experience in Azure or AWS is required; experience across both is strongly preferred.
  • Hands-on experience securing production AKS/EKS environments, including RBAC, network policies, workload identity, admission controls, image/runtime controls, and cluster hardening.
  • Proven experience with cloud network security, including firewalls, WAFs, network segmentation, and secure connectivity patterns.
  • Strong understanding of cloud security architecture, including shared responsibility models, secure service design, and defense-in-depth.
  • Experience with preventative security controls, including CSPM, policy enforcement, and secure cloud baselines.
  • Cloud automation experience using Infrastructure as Code tools such as Terraform, Bicep, or CloudFormation, plus scripting with Python, PowerShell, Bash, or similar languages.
  • Ability to operate independently, own complex problem spaces, and deliver practical, scalable solutions.
  • Strong communication skills and comfort providing architecture-level guidance to engineering teams.
  • Experience working in regulated environments.
