I'm representing a growing, seed-stage Australian healthtech company that builds AI-powered software, and they're looking for their second Senior Platform Engineer to own the infrastructure, security, and platform engineering end to end. From day-to-day reliability through to the automation and AI-agent tooling that makes the rest of the team faster.
This is a hands-on senior IC role for someone who wants genuine breadth: not just DevOps, not just SRE, but someone comfortable owning solutions design, security compliance, and the guardrails that let AI agents safely take on real engineering work.

You're balancing build-fast, seed-stage pace against real security and compliance stakes, given the platform handles sensitive clinical data. The platform is built to support global expansion, so the infrastructure and compliance foundations you put in place now will need to scale well beyond Australia

What the role involves:
Designing and building the "harness" AI agents operate within; the tools, permissions, and guardrails that let them safely execute real infrastructure and automation tasks
Writing and maintaining production-quality code for internal tooling and automation, with proper version control, testing, and code review




Building and maintaining CI/CD pipelines and infrastructure-as-code
Owning reliability, observability, and cost across a multi-cloud setting (GCP, AWS, Azure) - Running Kubernetes and container platforms
Leading solutions design for recent systems and integrations
Maintaining compliance against frameworks like ISO 27001, the Essential Eight, and Australian privacy standards
Taking part in a shared on-call roster
Acting as senior escalation point for internal support

What they're looking for:
Some hands-on experience with agentic engineering or AI-assisted operations tooling you don't need to be a deep expert, but you've used it for real work
Senior Engineers with Platform, DevOps, or SRE experience with genuine breadth across systems, cloud, and security
Solid software engineering fundamentals at least one language (e.g. Python, Go), git-based workflows, automated testing
Kubernetes and container runtime experience
Multi-cloud experience across GCP, AWS, and/or Azure
Exposure to security compliance frameworks (ISO 27001, Essential Eight, or similar)
