Platform Security Operations Manager

AI FactoryOS Operations
AI FactoryOS is Firmus' proprietary operating system for the AI Factory. It governs GPU telemetry, cooling, power and grid interaction as one integrated layer, so that every Firmus site can be optimised and monitored as a single system.
AI FactoryOS Operations runs that platform in production and owns the 24/7 reliability of AI FactoryOS, Firmus AI Cloud and the platforms built on them, together with the service levels the estate is measured against.
The remit is an engineering one. The function builds the guarded automation, remediation and operational tooling that turn manual response into a software-defined capability, and builds and operates the shared services the estate's own operation depends on. The function works closely with the engineering teams that build the platform, supplying the production evidence that shapes what they fix and what they build next.
Platform Security Operations Manager
Location : Sydney or Melbourne or Singapore with travel to Australian AI Factory sites as required.
Role Summary
Firmus runs large-scale, state-of-the-art AI infrastructure built on the latest generation of GPU rack-scale systems and operated as one estate to power the next generation of AI innovation. The Platform Security Operations Manager leads the Platform Security team and is the manager of the AI Factory's Computer Security Incident Response Team (CSIRT): the team that detects, responds to and recovers from security incidents across AI FactoryOS, Firmus AI Cloud, the platforms built on them and the tenant workloads they carry, and that operates the security controls which keep the AI Factory defensible as it grows.
This is a hands-on security leadership role. The role manages the AI Factory's security incident response capability: the 24/7 security on-call roster, the incident response plan and playbooks, the exercises that prove they work, and the coordination with incident command and with Cyber Security and Operations leadership when an incident is live. It also manages the operational security the team delivers in production: runtime detection and enforcement, the security gates in the delivery pipeline, the security content of the multi-tenant Kubernetes estate, the security exception register and the independent monitoring of privileged activity.
Key Responsibilities
Lead and manage the Platform Security team, including hiring, onboarding, performance, development and wellbeing across regions.
Manage the AI Factory's CSIRT and its 24/7 security on-call roster, so the team is ready to respond at any hour.
Manage the AI Factory security incident response plan: severity classification aligned to the function's severity model, and clear escalation paths from the operations and engineering teams.
