- Develop and maintain cloud security standards, patterns, guardrails and reference architectures.
- Configure and manage cloud-native security services including IAM, encryption, logging, network security and threat detection capabilities.
- Lead security reviews,



threat modelling and risk assessments for cloud-hosted applications and platforms.
- Implement and optimise cloud security controls across IaaS, PaaS, container and serverless environments.
- Partner with engineering teams to embed security into CI/CD pipelines and Infrastructure as Code (IaC) deployments.
- Build and maintain security controls aligned with Zero Trust principles.
- Support cloud migration and modernisation initiatives from a security architecture perspective.
- Drive remediation of cloud security findings identified through security assessments and posture management tools.
- Ensure compliance with banking and regulatory requirements including APRA CPS 234 and relevant security frameworks.
- Provide technical leadership and guidance to engineering teams on cloud security best practices.

Qualifications:

- 7+ years' experience in Cyber Security, Cloud Security, Security Engineering or Security Architecture.
- Strong hands-on experience securing AWS environments.
- Demonstrated experience across GCP and Azure security services and controls.
- Experience working within highly regulated environments such as banking, financial services, insurance or government.
- Proven experience implementing cloud security controls rather than solely providing advisory services.
- Strong understanding of cloud networking, identity, encryption and security monitoring across multi-cloud environments.
- Experience engaging with engineering, platform and DevOps teams in Agile delivery environments.
