Job description

Australia has the talent to build world-class AI infrastructure. We have always exported it.

We are done with that. If you have built at the highest level and you are ready to build something sovereign, something ours, this is the moment.

We have completed our PoC and are now scaling our sovereign cluster, this is hands-on infrastructure work from day one, not monitoring dashboards.

The platform we are building can run cancer research, scientific computing, and the AI workloads that actually matter for this country.

We are not building another SaaS tool. We are building infrastructure that changes what Australia can do.

If that is the kind of work you have been waiting for, come talk to us.

We are an early-stage Australian startup growing our DevOps team and hiring a DevOps and Cloud Engineer to help own the infrastructure layer reporting to the Director of DevOps.

This is a full-time role, Sydney based, with full working rights or permanent residency required.

What you will do

Own and operate our AWS environment: EC2 (including GPU instances), RDS, S3, IAM, CloudWatch, VPC and supporting services

Build a fully scripted teardown and startup cycle to control overnight and idle infrastructure costs

Build and maintain the provider integration layer that connects our orchestration engine across multiple compute environments

Stand up and maintain CI/CD pipelines and infrastructure-as-code for the whole platform

Configure performance reporting so it reflects real user-facing behaviour, excluding synthetic monitoring, health checks and internal test traffic Track infrastructure spend weekly and maintain a runbook and architecture summary suitable for technical and investor review.

What you will need

Strong hands-on AWS across EC2, RDS, S3, IAM, CloudWatch and VPC Proven infrastructure-as-code (Terraform, CDK or equivalent)

Experience building CI/CD pipelines for multi-service backends Containerised workload deployment and GPU instance management Monitoring and observability tooling (CloudWatch, Datadog or similar)

A genuinely cost-conscious mindset. You know what cloud costs and you manage it actively.

The infrastructure is not a support function here. It is the product. You will own it, and your work will directly shape whether this company succeeds.
