  • Guide reference implementations and support adoption across shared services and cloud landing zones.
  • Assess risks, recommend controls, and document architectural decisions and trade-offs for deviations from standards.
  • Lead architecture reviews and threat modeling for new systems, integrations, migrations, and emerging technologies.
  • Review multi-cloud platforms, modern application stacks, and AI and agentic systems.
  • Track findings and translate them into practical recommendations.
  • Align stakeholders on security trade-offs and support through implementation.
  • Ensure reference architectures, implementations, and guardrails are continuously updated.
  • Build relationships across teams, mentor engineers, and improve architecture review methods and knowledge base.

  • Strong analytical skills and sound judgment when balancing security risks, engineering constraints, and business needs.
  • Passionate about sharing knowledge across teams, the broader security community and to mentoring others.
  • Strong understanding of cryptography concepts and key management, authentication and authorization, identity federation, network and operating system security, data protection, and detection and response at the system level, network layer or application layer.
  • Hands-on experience and deep understanding of at least one major cloud provider (AWS, Azure, or GCP), including identity and access management, networking, and shared platform services.
  • Experience leading security architecture reviews, threat modelling, and risk assessments across multiple products or platforms, and translating findings into prioritized engineering actions.
  • Ability to develop security requirements, reusable design patterns, and reference architectures, and guide their adoption.
  • Experience translating security frameworks, standards, and applicable regulatory requirements into controls, assessment methods, and practical engineering guidance.
  • Experience designing and implementing secure applications, APIs, and container platforms, with knowledge of Kubernetes and secure CI/CD practices.
