Senior Cloud Security Engineer
Sydney CBD | Hybrid, 3 days in office

- AWS, Azure, Terraform, Landing Zones, Networking & Security
- Senior hands-on IC role with genuine platform ownership
- 5-year growth program offering significant career progression

About the role
We’re looking for a Senior Cloud Infrastructure & Security Engineer to join a growing technology environment and take ownership across AWS, Azure, Infrastructure as Code, networking and cloud security.

This is a senior individual contributor role, ideal for someone with a strong infrastructure and networking background who has progressed into Cloud Engineering and wants to remain technically hands-on.

AWS is the primary focus, alongside Azure, with significant engineering work across Terraform, AWS Landing Zones, account creation and onboarding, cloud networking, IAM, security controls, governance and automation.

The organisation is entering a five-year hyper-growth program, creating significant opportunity to increase your technical ownership and progress towards Lead, Principal or Architecture-level responsibilities while remaining on the technical IC pathway.

What you’ll do

- Design, build and operate secure AWS infrastructure using Terraform and reusable IaC patterns.
- Support and improve Azure infrastructure within a multi-cloud environment.
- Build and evolve multi-account AWS environments.
- Manage AWS account creation, onboarding, governance and guardrails.
- Design and improve AWS Landing Zones, including AWS Organisations, Control Tower or equivalent.
- Drive the adoption of Terraform and Infrastructure as Code across the environment.
- Design and support cloud networking across AWS and Azure,



including centralised networking and connectivity.
- Implement IAM, network security, governance and automated cloud security controls.
- Build reusable Terraform modules, patterns and engineering standards.
- Develop automated infrastructure deployment through Git and CI/CD.
- Troubleshoot complex production infrastructure and cloud issues.
- Work closely with Infrastructure, Cyber Security and Data & AI teams.

The role combines hands-on AWS and Azure engineering with genuine ownership across IaC, networking, security and platform standards.

What you’ll bring

- Robust hands-on AWS engineering experience.
- Advanced Terraform / Infrastructure as Code capability.
- Experience designing and supporting multi-account AWS environments.
- Experience with AWS Landing Zones, ideally AWS Organizations, Control Tower, Landing Zone Accelerator or equivalent.
- Practical experience supporting Azure infrastructure.
- A strong background in infrastructure engineering.
- Strong networking knowledge, including routing, connectivity and centralised cloud networking.
- Good understanding of network security, IAM, cloud security and governance.
- Experience implementing security controls and guardrails through automation and IaC.
- Experience with Git, CI/CD and automated infrastructure delivery.




- Strong production troubleshooting and problem-solving skills.
- The ability to influence technical direction and establish engineering standards while remaining hands-on.

Advanced Terraform, AWS infrastructure, Azure, networking, security, IAM and cloud governance are central to the technical requirements of the role.

Why join?
This is an opportunity to own and improve a cloud platform rather than simply maintain one.

You’ll have significant hands-on involvement across AWS, Azure, Terraform, Landing Zones, account creation, infrastructure, networking and security, with the autonomy to improve engineering standards and influence how the environment develops.

Most importantly, this is a senior IC opportunity with genuine progression. The organisation is embarking on a major five-year growth program, meaning the scale and complexity of the technology environment will continue to increase.

For someone who wants to stay technical, take on greater ownership and eventually progress towards Lead, Principal or Architecture-level responsibilities, there is significant runway to grow with the business.
