About the Opportunity

We’re looking for an AWS DevSecOps Engineer to join a consulting team building a new enterprise AI platform for a major Australian organisation.

This is a greenfield environment designed to give teams a secure, self-service way to build and deploy AI solutions on AWS.

Rather than security being something checked at the end, the focus is on building security, governance and automated controls directly into the platform from day one.

The Role

You’ll work as part of a small engineering squad responsible for building the underlying cloud and security foundations of the AI platform.

Your role will bring the security lens to the team — understanding what controls need to exist, identifying gaps within AWS environments, and then helping translate those requirements into automated, scalable engineering solutions.

Day to day, you’ll be involved in:

• Reviewing AWS environments and identifying required security controls
• Building and automating cloud security controls using Terraform / Infrastructure as Code
• Embedding security into CI/CD and self-service deployment workflows
• Working with IAM, authentication, credentials and access controls
• Translating security requirements into technical controls and Policy as Code
• Working with AWS Service Control Policies (SCPs)
• Supporting secure provisioning through GitHub Actions and/or Azure DevOps
• Reviewing new AI services and determining how they should be securely deployed
• Working alongside platform, SRE/observability and DevSecOps engineers
• Advising the wider squad on security considerations as new capabilities are built

What we're looking for

You don’t need to tick every box.

The strongest candidates will likely come from cloud security, DevSecOps or security engineering and have enough cloud engineering experience to be genuinely hands-on.

Ideally, you’ll bring:

• Strong commercial AWS experience
• DevSecOps or cloud security experience
• Terraform / Infrastructure as Code
• CI/CD experience
• AWS IAM and cloud access/security controls
• Security automation experience
• Understanding of AWS SCPs and/or Policy as Code
• GitHub Actions and/or Azure DevOps
• Scripting capability
• Ability to assess an environment, identify security requirements and help implement the solution
• Strong communication skills and the ability to work within a client-facing consulting environment

Experience with AWS landing zones would be advantageous.

What about AI experience?

You don't need years of AI experience.

You do need to be curious about it.

The platform will support enterprise AI workloads, with the initial engagement involving AWS AI services including Amazon Bedrock and AgentCore.

We’d love to speak with engineers who are already exploring these technologies — whether commercially, through side projects, labs or their own learning — and who are interested in the emerging challenge of securing AI infrastructure and services at enterprise scale.

Why consider it?

This isn't a traditional security role focused on reviewing controls after something has already been built.

You'll be joining at the beginning of a new AI platform build, working alongside engineers to determine how security should be designed into the environment from the outset.

The consultancy is also building this capability for the longer term, with similar cloud, security and AI skillsets expected to be required across future client engagements.

If your background sits somewhere between AWS engineering, cloud security and DevSecOps, we'd be keen to hear from you — even if you don't match every technology listed above.
